I need to implement clone method in theAdvancedDataGrid class

I need to implement clone method in theAdvancedDataGrid class, to copy the object in its completeness Could anyone give me a helping hand.

Hi Nikos,
from youe question it's not clear what do you need to copy: data, parts of ADG (GUI) or something else?
If it's not a GUI - only data - you can use mx.utils.ObjectUtil.copy(value:Object):Object

Need help in compare method of Comparator class

I am writing a program that will display elements of a TreeMap in an order in which I want. By default the order is ascending. To change the order I need to override the compare method of the Comparator class.
I've done this in my code below.
I want to display keys with lower-case 1st and then those with upper-case.
Please help.
import java.util.*;
public class MyComparator implements Comparator {
public int compare(Object o1, Object o2) {
    String s1 = o1.toString();
    String s2 = o2.toString();
    return s1.compareTo(s2);
public static void main(String[] args) {
    Map names = new TreeMap(new MyComparator());
    names.put("a", new Integer(1435));
    names.put("b", new Integer(1110));
    names.put("A", new Integer(1425));
    names.put("B", new Integer(987));
    names.put("C", new Integer(1323));
    Set namesSet = names.keySet();
    Iterator iter = namesSet.iterator();
    while(iter.hasNext()) {
      String who = (String)iter.next();
      System.out.println(who + " => " +     names.get(who));
}

public int compare(Object o1, Object o2) {
    String s1 = o1.toString();
    String s2 = o2.toString();
    String ss1 = beginsWithLowerLetter(s1)? s1.toUpperCase() : s1.toLowerCase();
    String ss2 = beginsWithLowerLetter(s2)? s2.toUpperCase() : s2.toLowerCase();
    return ss1.compareTo(ss2);

WOW, Im not sure what you are trying to do.
What was the compiler error?
Just an observation,
Both of your getRandom() and getRandom2(), you pass in 7 parameters and do nothing with them. you really do not need to do this. Also both of those methods do exactly the same thing, the same way. Thats just redundant.
You could say something like:
     public static int newRandom(){
        return (int) (1 + Math.random() * 7);
    }Also check your method signature for the
public static double alcoholicCon(int o, int p,){I see your error, do you? Hint: too much punctuation...
Also, you should initialize your method variables to a value.
Darn too slow...

Implementing UIApplicationDelegate protocol methods in NSObject class not working.

Hi Everyone,
I am new bee in iphone developement. I want to implement UIApplicationDelegate protocol methods in one of my NSObject class, how can i implement that help me please.
I have mentioned the sample code what acutal i want to impelment.
.h file
@interface SmaplClass : NSObject <UIApplicationDelegate>
.m file
- (void)applicationWillResignActive:(UIApplication *)application
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
Want to implement the above methods is NSObject class to be implemented or used, its not working. Help me can do it.
Please help me
Thanks,

I complete the above discussion with saying that it is better to implement the notification handling methods in your app delegate. If there are good reasons to not to do so, you have to implement the methods in another class, instantiate the class, and call the methods from the actual UIApplicationDelegate protocol methods in the AppDelegate object. This way you can remove the actual notification handling code from AppDelegate class.
For example, suppose you implemented the methods in the class called Test. This is a sample code in the AppDelegate class:
@implementation AppDelegate
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
 Test *t = [[Test alloc] init];
 [t application: application didReceiveRemoteNotification: userInfo];
@end
Or you can create an association relationship between the AppDelegate and Test, so you do not have to create a new Test instance in each of the remote notification handling methods:
@interface AppDelegate {
 Test *test;
@end
@implementation AppDelegate
+ (id)init {
 if (self = [super init]) {
 test = [[Test alloc] init];
 return self;
- (void)dealloc {
 [test release];
 [super dealloc];
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
 // No need to create a Test instance. You just forward the call from AppDelegate instance to test // instance
 [test application: application didReceiveRemoteNotification: userInfo];
@end

Implementation of method

hi Frnds,
i have got a class which is having a interface method. I want to implement that method in that class only. but when i Double Click on it then it is showing that it is implementated in a different class.
how can i implement it in that class only.
Thanks
Rohit

Hi ROHIT,
when i double click on the interface it shows me that it is implemented in the superclass
As interface is always implemented in public section of a class, it is already implemented in all its subclasses. Therefore you already have the implementation done. As my predecessors said you cannot control were it is implemented (besides your implementation), but you can redefine it. It will then have a different implementation than it has in superclass. Without this your class cannot impelemnt it once again as name conflict would arise. This is because you already have one implementation of that interface method in you public section (made in supperclass).
Hope this is clear

How to implement clone() with Evolvable POF and maintain future data.

POF evolvable objects support backward compatibiliy by maintaining "futureData".
If my client needs to clone a POF Evolvable (i.e. one that extends com.tangosol.io.AbstractEvolvable) before changing it and then writing it back to the cache , how does one implement clone and maintain future data?
Cheers,
Neville.

Hi Rob -

Peace,
Cameron Purdy | Oracle CoherenceHi Cameron,
considering that PortableObjectSerializer writes the greater of implementation and data version as version id at serialization, it means that it assumes that an implementation from a later version than the data ALWAYS upgrades the data to the implementation version, it is correct that way.
On the other hand, if you wrote a serializer which does not make an assumption, but allows for optional and partial upgrades (to interim versions), you wouldn't be able to use AbstractEvolvable.getDataVersion() as a way of getting the old data version as it won't allow you to increase the data version once you upgraded the data with code in the data class called by the serializer. Ehh... it is a bit confusing as I wrote it down... An example:
You can't do this:
class A extends AbstractEvolvable {
    void upgradeState() {
        int dataVersion = getDataVersion();
       // initialize new attributes
        int newDataVersion = ...; // appropriate to what we upgraded
        // this triggers assertion failure
        setDataVersion(newDataVersion);
class ASerializer {
   Object deserialize(PofReader reader) {
      A newInstance = new A();
      a.setDataVersion(in.getVersionId());
      // set fields ...
      a.setFutureData(...);
      a.upgradeState();
      return newInstance;
}Instead, you have to do this (set the dataVersion to the instance AFTER upgrading the state, and therefore you have to pass the data version to the upgrade method):
class A extends AbstractEvolvable {
    int upgradeState(int dataVersion) {
       // initialize new attributes
        int newDataVersion = ...; // appropriate to what we upgraded
        return newDataVersion;
class ASerializer {
   Object deserialize(PofReader reader) {
      A newInstance = new A();
      int dataVersion = in.getVersionId();
      // set fields ...
      a.setFutureData(...);
      dataVersion = a.upgradeState(dataVersion);
      a.setDataVersion(dataVersion);
      return newInstance;
}Best regards,
Robert

Force Derived Class to Implement Static Method C#

So the situation is like, I have few classes, all of which have a standard CRUD methods but static. I want to create a base class which will be inherited so that it can force to implement this CRUD methods. But the problem is, the CRUD methods are static. So
I'm unable to create virtual methods with static (for obvious reasons). Is there anyway I can implement this without compromising on static.
Also, the signature of these CRUD methods are similar.
E.g. ClassA will have CRUD methods with these type of Signatures
public static List<ClassA> Get()
public static ClassA Get(int ID)
public static bool Insert(ClassA objA)
public static bool Update(int ID)
public static bool Delete(int ID)
ClassB will have CRUD signatures like
public static List<ClassB> Get()
public static ClassB Get(int ID)
public static bool Insert(ClassB objB)
public static bool Update(int ID)
public static bool Delete(int ID)
So I want to create a base class with exact similar signature, so that inherited derived methods will implement their own version.
For E.g. BaseClass will have CRUD methods like
public virtual static List<BaseClass> Get()
public virtual static BaseClassGet(int ID)
public virtual static bool Insert(BaseClass objBase)
public virtual static bool Update(int ID)
public virtual static bool Delete(int ID)
But the problem is I can't use virtual and static due to it's ovbious logic which will fail and have no meaning.
So is there any way out?
Also, I have few common variables (constants) which I want to declare in that base class so that I don't need to declare them on each derived class. That's why i can't go with interface also.
Anything that can be done with Abstract class?

Hi,
With static methods, this is absolutely useless.
Instead, you could use the "Singleton" pattern which restrict a class to have only one instance at a time.
To implement a class which has the singleton pattern principle, you make a sealed class with a private constructor, and the main instance which is to be accessed is a readonly static member.
For example :
sealed class Singleton
//Some methods
void Method1() { }
int Method2() { return 5; }
//The private constructor
private Singleton() { }
//And, most importantly, the only instance to be accessed
private static readonly _instance = new Singleton();
//The corresponding property for public access
public static Instance { get { return _instance; } }
And then you can access it this way :
Singleton.Instance.Method1();
Now, to have a "mold" for this, you could make an interface with the methods you want, and then implement it in a singleton class :
interface ICRUD<BaseClass>
List<BaseClass> GetList();
BaseClass Get(int ID);
bool Insert(BaseClass objB);
bool Update(int ID);
bool Delete(int ID);
And then an example of singleton class :
sealed class CRUDClassA : ICRUD<ClassA>
public List<ClassA> GetList()
//Make your own impl.
throw new NotImplementedException();
public ClassA Get(int ID)
//Make your own impl.
throw new NotImplementedException();
public bool Insert(ClassA objA)
//Make your own impl.
throw new NotImplementedException();
public bool Update(int ID)
//Make your own impl.
throw new NotImplementedException();
public bool Delete(int ID)
//Make your own impl.
throw new NotImplementedException();
private CRUDClassA() { }
private static readonly _instance = new CRUDClassA();
public static Instance { get { return _instance; } }
That should solve your problem, I think...

How to implement find methods in CMP?

As OC4J does not support EJB-QL, we need to implement the find methods by ourselves. But how? Here is my thought.
1) Still declare the find methods in EJB home, such as
public Collection findBySponsor(String sponsorGuid);
2) Do not add query part to ejb-jar.xml file;
3) In the bean class, implement the find method using JDBC code.
Does CMP allows explicit-implementation of finder methds?
Does CMP allows explicit-call to JDBC code?
Thanks,

Henry -- Why go to that trouble? For the near term I would suggest that you just modify the generated
orion-ejb-jar.xml descriptors which will include tags to allow you to either 1) enter a partial criteria or
2) enter a complete SQL statement. This is much less work and when EJB-QL is available with the product,
then you have to only add the EJB-QL to the ejb-jar.xml.
Thanks -- Jeff

When do we override our own clone method not the Object class clone method

Hi,
I have a confusion in overriding clone method.We can create clone object by writing Object.clone() but some times I have seen writing our own clone method ,when do we write this,also clone() is defined protected and when we write our own clone it is said to write it public,why?
Thanks
Sumit

protected methods can only be called in the same class and it subclass. You can make clone protected if this is all you need.
However if you need to clone() the object from another class, it need to be public.
This is the same for any method.
Also as Object.clone() is protected you cannot make it private or package-local (this is true of any protected method)

Why do we need get and set methods?

It is considered good design practice to keep all class data private and
provide get and set methods for accessing the data in a controlled
manner.
So, instead of directly accessing the class data, you use getter and setters.
I do not really feel the need to use get and set methods.
How does that achieve encapsulation when ultimately the class data is being exposed?

A couple of reasons why to use get and set:
1. For example you can set an int value for month, if a user sets this to somting
higher than 12 (or 11 if it's zero based) you want to handle that by either
throwing an exception or adding a year for every time it can be devided by 12.
If you dont do it in set you'll have a whole bunch of methods that might need to
correct the value before retreiving the eventual date.
2. If for some reason you have security set up for certain values you can
implement this in the get method. When this is done somewhere else you have
a whole bunch of methods retreiving the info in other classes that need to check
first. (a canGet method could allso be used). Another good reason to use get
is when the information needs to be converted depending on the consumer
calling the get method.
3. If any logic in 1 or 2 changes you'll have a bunch of code to change.
If you feel there is no need to implement any security, error handling (on
compiling because get and set might throw something) or validation when
setting/getting these values there is still the argument of readabillity.
Eclipse has a feature that will generate getters and setters for you so it's not
like there is a lot of extra typing involved.
Got interupted whyle typig so sorry to repeat any answer given before.

Implementing Business Add-Ins (BADI) 
The use of object orientated code within SAP has lead to new method of enhancing standard SAP code called
Business Add-Ins or BADI's for short. Although the implementation concept is based on classes, methods and
inheritance you do not really have to understand this fully to implement a BADI. Simply think of methods
as a function module with the same import and export parameters and follow the simple instructions below.
Steps:
1. Execute Business Add-In(BADI) transaction SE18
2. Enter BADI name i.e. HRPBSGB_HESA_NISR and press the display
 button
3. Select menu option Implementation->Create
4. Give implementation a name such as Z_HRPBSGB_HESA_NISR
5. You can now make any changes you require to the BADI within this
 implementation, for example choose the Interface tab
6. Double click on the method you want to change, you can now enter
 any code you require.
7. Please note to find out what import and export parameters a
 method has got return the original BADI definition
 (i.e. HRPBSGB_HESA_NISR) and double click on the method name
 for example within HRPBSGB_HESA_NISR contract is a method
8. When changes have been made activate the implementation

Need badi implementation

hi to all experts,
i need to implement sap predefined badi plz send me with screen shots how to implement predefined sap badis

Hi
Business Add-Ins
Business Add-Ins are a new SAP enhancement technique based on ABAP Objects. They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery. Since specific industries often require special functions, SAP allows you to predefine these points in your software.
As with customer exits (SMOD/CMOD [Page 40]), two different views are available:
In the definition view, an application programmer predefines exit points in a source that allow specific industry sectors, partners, and customers to attach additional software to standard SAP source code without having to modify the original object.
In the implementation view, the users of Business Add-Ins can customize the logic they need or use a standard logic if one is available.
In contrast to customer exits, Business Add-Ins no longer assume a two-system infrastructure (SAP and customers), but instead allow for multiple levels of software development (by SAP, partners, and customers, and as country versions, industry solutions, and the like). Definitions and implementations of Business Add-Ins can be created at each level within such a system infrastructure.
SAP guarantees the upward compatibility of all Business Add-In interfaces. Release upgrades do not affect enhancement calls from within the standard software nor do they affect the validity of call interfaces. You do not have to register Business Add-Ins in SSCR.
The Business Add-In enhancement technique differentiates between enhancements that can only be implemented once and enhancements that can be used actively by any number of customers at the same time.
In addition, Business Add-Ins can be defined according to filter values. This allows you to control add-in implementation and make it dependent on specific criteria (on a specific Country value, for example). All ABAP sources, screens, GUIs, and table interfaces created using this enhancement technique are defined in a manner that allows customers to include their own enhancements in the standard.
A single Business Add-In contains all of the interfaces necessary to implement a specific task. In Release 4.6A, program and menu enhancements can be made with Business Add-Ins. The actual program code is enhanced using ABAP Objects. In order to better understand the programming techniques behind the Business Add-In enhancement concept, SAP recommends reading the section on ABAP Objects

it_flights type table of sflight.
format color col_heading.
write:/ 'Flight info of:', i_carrid, i_connid.
format color col_normal.
select * from sflight
into corresponding fields of table it_flights
where carrid = i_carrid
and connid = i_connid.
loop at it_flights into wa_flights.
write:/ wa_flights-fldate,
wa_flights-planetype,
wa_flights-price currency wa_flights-currency,
wa_flights-seatsmax,
wa_flights-seatsocc.
endloop.
BBB

*Initialise the object of the interface.
data: exit_ref type ref to ZCL_IM_IM_LINESEL,
exit_ref1 type ref to ZIF_EX_BADISPFLI1.
selection-screen begin of block b1.
select-options: s_carr for spfli-carrid.
selection-screen end of block b1.
start-of-selection.
select * from spfli into corresponding fields of table it_spfli
where carrid in s_carr.
end-of-selection.
loop at it_spfli into wa_spfli.
write:/ wa_spfli-carrid,
wa_spfli-connid,
wa_spfli-cityfrom,
wa_spfli-deptime,
wa_spfli-arrtime.
hide: wa_spfli-carrid, wa_spfli-connid.
endloop.
at line-selection.
check not wa_spfli-carrid is initial.
create object exit_ref.
exit_ref1 = exit_ref.
call method exit_ref1->lineselection
EXPORTING

i_connid = wa_spfli-connid.
clear wa_spfli.
u can find BADI's in different ways...
1>First go to any transaction->iN THE menu bar SYSTEM->STATUS->Get the program name ->double click->u will go to the program attached to the tcode.Now search term will be CALL CL_EXITHANDLER.Now u will get list of BADI'S available..
2>Goto SE24->Give class name as CL_EXITHANDLER->Display->double click on get_instance mathod->Now u will go inside the method->Now put break point on the cl_exithandler.Now go to any transaction code and pass dat..U will see that it will be stopped on the break point which u set on the cl_exithandler...In the exit name u can find list of badi's attached to the tcode..
There are multiple ways of searching for BADI.
Finding BADI Using CL_EXITHANDLER=>GET_INSTANCE
Finding BADI Using SQL Trace (TCODE-ST05).
Finding BADI Using Repository Information System (TCODE- SE84).
1. Go to the Transaction, for which we want to find the BADI, take the example of Transaction VD02. Click on System->Status. Double click on the program name. Once inside the program search for CL_EXITHANDLER=>GET_INSTANCE.
Make sure the radio button In main program is checked. A list of all the programs with call to the BADIs will be listed.
The export parameter EXIT_NAME for the method GET_INSTANCE of class CL_EXITHANDLER will have the user exit assigned to it. The changing parameter INSTANCE will have the interface assigned to it. Double click on the method to enter the source code.Definition of Instance would give you the Interface name.
2. Start transaction ST05 (Performance Analysis).
Set flag field "Buffer trace"
Remark: We need to trace also the buffer calls, because BADI database tables are buffered. (Especially view V_EXT_IMP and V_EXT_ACT)
Push the button "Activate Trace". Start transaction VA02 in a new GUI session. Go back to the Performance trace session.
Push the button "Deactivate Trace".
Push the button "Display Trace".
The popup screen "Set Restrictions for Displaying Trace" appears.
Now, filter the trace on Objects:
V_EXT_IMP
V_EXT_ACT
Push button "Multiple selections" button behind field Objects
Fill: V_EXT_IMP and V_EXT_ACT
All the interface class names of view V_EXT_IMP start with IF_EX_. This is the standard SAP prefix for BADI class interfaces. The BADI name is after the IF_EX_.
So the BADI name of IF_EX_CUSTOMER_ADD_DATA is CUSTOMER_ADD_DATA
3. Go to Maintain Transaction (TCODE- SE93).
Enter the Transaction VD02 for which you want to find BADI.
Click on the Display push buttons.
Get the Package Name. (Package VS in this case)
Go to TCode: SE84->Enhancements->Business Add-inns->Definition
Enter the Package Name and Execute.
Here you get a list of all the Enhancement BADIs for the given package MB.
The simplese way for finding BADI is
1. chooes Tcode Program & package for that Tcode.
2. Go to Tcode se18
3. Press F4
4. search by package or by program.

Use VB Set keyword with Clone method?

I am using the TestStand API with Visual Basic 6.0 SP5. Is is necessary to use the Set keyword when calling the Clone method of a PropertyObject? i.e. which is correct:
Set thePropObj = existingPropObj.Clone("", 0)
or
thePropObj = existingPropObj.Clone("", 0)
Seems the Set keyword would be required, but I am
running into funny problems with this. I have a step
that I am trying to create a copy of. (The step contains a call to a LabVIEW VI.) If I omit the Set keyword, execution hangs at the call to Clone. If I include the Set keyword, all information present in the original PropertyObject doesn't seem to get copied to the new one. (Also, oddly enough, if I omit the set keyword, and the step calls a CVI function, everything seems to work
fine!)
Anyone have any advice?
Thanks in advance
D. LaFosse

Hello LaFosse,
You need to use the Set keyword before the clone method statement. However, I have a couple of comments about the code you sent.
This is the code you sent:
' Start up the testStand engine
Dim theTS As TS.Engine
Set theTS = New TS.Engine
' OK, load in the sequence file I
' created. This sequence file
' contains nothing more than a call
' to a VI in the main stepgroup of
' the MainSequence.
Dim seqFile As SequenceFile
Set seqFile =
theTS.GetSequenceFile()
' get a handle to the MainSequence
Dim seq As Sequence
Set seq = seqFile.GetSequenceByName
("MainSequence")
' Get a handle to the step that calls
' the VI, and a property object for
' the step
Dim theStep As Step
Set theStep =
seq.GetStep(0, StepGroup_Main)
Dim theStepProp As PropertyObject
Set theStepProp =
theStep.AsPropertyObject
' Create another step. We will attempt
' to use Clone to fill in the
' properties of this step.
Dim theOtherStep As Step
Dim theOtherStepProp As PropertyObject
Set theOtherStep = theTS.NewStep("",
TS.StepType_Action)
Set theOtherStepProp =
theOtherStep.AsPropertyObject
' Call clone...this step will hang.
theOtherStepProp =
theStepProp.Clone("", 0)
Basically the problem is that you are not loading the TypePallete after creating the engine. You shoud include right after the Set theTS = New TS.Engine:
theTS.LoadTypePaletteFiles
This should avoid the crash.
Some Additional comments:
1. With VB you don't need to create property objects from other objects. All the classes, except the Engine Class, inherit from the Property Object Class. The following Code does the same thing, but without creating propertyobjects directly:
Sub MySub()
'Variable Declaration
Dim theTS As TS.Engine
Dim seqFile As SequenceFile
Dim seq As Sequence
Dim theStep As Step
Dim theOtherStep As Step
'Create the Engine
Set theTS = New TS.Engine
'Load the Types
theTS.LoadTypePaletteFiles
'Get Sequence File
Set seqFile = theTS.GetSequenceFile()
'Get Sequence
Set seq = seqFile.GetSequenceByName("MainSequence")
'Get Step
Set theStep = seq.GetStep(0, StepGroup_Main)
'Clone the Step
Set theOtherStep = theStep.Clone("", 0)
'Using the inheritance functionality
'gets the Step Status
'Notice that theOtherStep is not a PropertyObject
'and you can use all the properties and methods that
'applies to the PropertyObject Class to a Step class
'in this example
'Also, in VB when you are typing the statement, you
'will not see the PropertyObject Class properties and
'and Methods automatically if the variable is not a
'PropertyObject type. However, you can still use them
'as mentioned before
MsgBox (theOtherStep.GetValString("Result.Status", 0))
End Sub
2. When you create or modify sequence files programatically be carefull not to break the license Agreement. You need the development lisence when modifying sequences.
3. This piece of code is not completed, and you will need to shutdown the engine by the end.
4. Since you are not handling UI Messages, you will need to be carefull when loading sequences that have the SequenceFileLoad Callback. The engine posts UI Messages when executing this callback. Also when you shutdown the engine, UI Messages are posted. For both operations (Load Sequence and Shuutdown) you may prevent the engine from posting the message (You may check the options parameter for this two methods in TS Programmer Help.)
5. If you want to run a sequence, again you will need to incorporate in your code the UIMessage Handler part. (You may check the TS Programmer Help->Writing an Application Using the API->UI Messages). Otherwise it may hang since the engine posts UI Messages eventually.

XmlBean usage and the clone() method.

I'm trying to use the XmlBean class as the superclass for all our business objects and we have an issue with the usage of the clone method.
Basically our business objects all throw the CloneNotSupportedException (as per Object.clone() signature) while XmlBean.clone() does not throw it. Introducing XmlBean into the hierarchy will cause quite a bit of effort to change clone() signatures for a lot of classes. So, we were wondering if there is any alternative to subclassing XmlBean while at the same time using the efficient caching that it gives us. I guess I'm looking for a "composition" approach rathe than an "inheritance" approach that might work.
Has anyone faced this issue and is there any other workaround?
Thanks,
--Das

The reason that I asked is that the exception is "old baggage" from a design flaw in the original JDK 1.0 .. it is a checked exception that can never happen on an object that implements Cloneable, so if you don't throw it, and you implement Cloneable, then it won't be thrown on clone().
