Identifying Unused public Methods in an Application

Is there any other open source that identifes the unused public methods? I have come across many open source that identifies and removes the unused public methods. But, I need only to identify and report it. If anyone knew about any of the open source package that does it, please let me know.

Hi Epesh,
I have found an Open Source Package named PMD from SourceForge that identifies the Unused Private methods,Unused Formal parameters and Reports them.
So if u know any Open Source Package which identifies the Unused Public Methods and reports them,please let me Know.
thanks & regards

Lint Tool to detect unused public methods?

I'm looking for a java lint tool that will point out public methods that
are unused within my codebase. All of the tools I've reviewed to date
have only detected unused private methods. Does such a tool exist?
If so, can you point me in the right direction?

I don't think such a tool can exist, because the tool wouldn't know whether your writing an API or an end user application.
Also, in any program you might end up with public methods that do nothing, but need to be there to complete an interface implementation.
Presumably, the goal with finding the unused public methods is to remove them and to improve performance somehow. I don't think this is a worthwhile exercise as the compiler does a pretty good job of this optimisation already.

Identifying non-public methods

Is there any way for an object to idenify its own non-public methods (getMethods() returns only those methods that are declared public)?

getDeclaredMethods() - I believe this might do what you want. It throws a SecurityException, but I'm not sure exactly under what circumstances! Oh, and it doesn't return methods defined on any superclasses.

Problem with local class, static private attribute and public method

Hello SDN,
Consider the following situation:
1) I have defined a LOCAL class airplane.
2) This class has a private static attribute "type table of ref to" airplane (array of airplanes)
3) A public method should return the private static table attribute
Problems:
a) The table cannot be given as an EXPORTING parameter in the method because TYPE TABLE OF... is not supported and I get syntax errors. I also cannot define a dictionary table type because it is a local class.
b) The table cannot be given as a TABLES parameter in the method because TABLES is not supported in the OO context.
c) The table cannot be given as an EXPORTING parameter in the method defined as LIKE myStaticAttribute because my method is PUBLIC and my attribute is PRIVATE. ABAP syntax requires that all PUBLIC statements are defined before PRIVATE ones, therefore it cannot find the attribute to reference to with LIKE.
I see only 2 solutions:
a) Never ever use local classes and always use global classes so that I might define a dictionary table type of my class which I can then use in my class.
b) Make the attribute public, but this goes against OO principles, and isn't really an option.
Am I missing anything here, or is this simply overlooked so far?

Hello Niels
Since your class is local and, thus, only know to the "surrounding" application is does not really make sense to make it public to any other application.
However, if you require to store instances of your local classes in internal tables simply use the most generic reference type possible, i.e. OBJECT.
The following sample report shows how to do that. Furthermore, I believe it also shows that there are no serious inconsistency in the ABAP language.

Including External LVOOP Public Methods in Executable

Hello,
I have an application which on the top level must 'talk' to several different instruments; a LabJack UE9 (USB) , a Newport Motion Controller (USB-Serial), etc.    When I wrote the drivers for these instruments in LV, I used the LVOOP functionality and created individual Classes with public methods for each of the different devices I need to communicate with. Sounds logical to me, anyway.
In my top-level application, I call the public methods (and must include local instances of the LVOOP classes) for those independant instrument-specific classes. In the development mode, everything works peachy.   However, when I go to build the application executable (build), I get some weird behavior;
Firstly, with the default setting in 'Additional Exclusions' in the Build Properties of 'Remove as much as possible', I get errors when the builder gets to my independent classes. I get the message:
"An error occurred while building the following file:
C:\Documents and Settings\Wes Ramm\My Documents\Projects\RDT\LabJack\Class\Common Methods\Get DO Line State.vi
The VI became broken after disconnecting type definitions. Open the Build Specification and choose a different option on the Additional Exclusions page."
Ok, it seems that the class object is not linking, but I can get around that by selecting the second option in 'Additional Exclusions' ; 'Remove unreferenced project library members'. BUT, when the build is done, I get a couple of subdirectories with vi's named for all the different class methods for each independent that I am calling. There is no front panel or block diagram for the vis, so it looks like they are correctly 'included' in the build, but it seems cumbersome to include these subdirectories.
I even tried to 'add' the independant classes to the project by 'Add Folder', but got the same behavior.
The classes that I made are not a part of the top level VI, and the top Leve VI is not a member of any of the classes, so this I think is the crux of the matter. However, I am instantiating only the public methods, and the problems only pop up when I try to build the executable.
Am I missing something? Is there a more elegant way to do this? Any advise / tutorials / knowledgebase articles you can point me to?
The tree for the directory structure for my build looks like this (for reference)
\\Application Directory\
                         Executable
                         \Config
                                  \ Class One.lvclass (first external class that I am calling in my top-level vi)
                                      \ Method 1
                                      \ Method 2
                                      \ Method 3
                                     \ etc
                                  \ Class Two.lvclass
                                        \Method 1
                                        \Method 2
                                        \Method 3

Hello Wes Ramm,
It's better late than never! Hence I'm going to address some of the issues that you've brought up.
1) Which version of LabVIEW are you using? LabVIEW 8.5 has fixed a lot of issues that occured between the Application Builder and LV Classes. If you were using LV 8.2, I would suggest changing to LV 8.5 or at least LV 8.2.1
2) Apart from setting "Do not disconnect type definitions or remove unreferenced members" in the Additional Exclusions page, I would suggest also checking the box against "Enable Debugging" on the Advanced Page.
The following forum post has discussed many of the problems that have come up when building an executable which uses LVOOP classes. Hope this helps.

Public pages in authenticated application (NTLM)

I've been using a custome authentication method based on the NTLM Authentication method documented in the [white paper|http://www.oracle.com/technology/products/database/application_express/pdf/apex_ntlm_authentication_wp.pdf] for a while now with no problems.
This basically does the following 2 steps:
1) Standard NTLM Auth
2) Check returned user ID exists in a seperate table containing valid users
I've recently been working on an application where the bulk of the application is restricted to users with relevant permissions to edit the data. However there needs to be a public search facility open to anyone.
I was assuming that I'd be able to do this by just setting the authentication of the relevant page to "Page is Public", however this has presented a problem.
When I run the app as a user which passes both steps above (ie. auth succeeds), everything works fine.
However when I run as a user which fails step 2 above (auth fails) the public page loads fine, but whenever anything is posted I get an error like
Expecting p_company or wwv_flow_company cookie to contain security group id of application owner.
Error ERR-7621 Could not determine workspace for application (:) on application accept. Also this problem only rears it's head in IE (tried in 7&8), everything works fine in Firefox.
Also I've created a seperate application with just the public page (and the application set to use the DATABASE auth (i.e. no auth)) and this works fine.
This is fine as a workaround in this one instance, but i suspect there is likely to be call for similar public pages in other applications, and I don't want to have to create seperate apps for these unless I really have to.
Anyone any ideas about what the cause of the problem may be, or even pointers about where to look?

Try Page properties, Security tab, Authentication setting. It has values: Page requires authentication (default) / page is public. Havent tried though..
Just tried. it works. i manually changed page address in address line like http://something.lt:7777/pls/htmldb/f?p=103:19:3411287399936455. The user connected is "nobody". Public page is page 19.

Delegate class to access non-public methods during testing?

In the following video, towards the end, someone asked that FlexUnit assumes functions and methods are to be public when tested.
http://tv.adobe.com/watch/max-2008-develop/testing-your-flex-applications-by-michael-labri ola/
The speaker replied (@ 52:25), to use Delegate classes, which are linked in when being tested.
Can someone show me an example of this? Thanks.

Mike, thanks for the reply!
As I am new to unit testing, things are still solidifying. I do understand that Unit Testing, “tests the smallest functional unit of code”, which are methods and functions. However, I incorrectly assumed that *every* method needed to be tested *directly*. Hence, I thought all methods would have to be public. So that would have blown encapsulation out of the water. Now I understand from your reply, that private methods get tested indirectly from public methods. And that seems more ideal.
Thanks again.

Starting Public Worflows Within An Application

The documentation for starting a public workflow within an application is ambiguous.
At the following location: http://e-docs.bea.com/wlintegration/v2_0/collaborate/workflow/start.htm#1331638
you state that a workflow instance is retrieved using the startWorkflow method.
Unfortunately, this is a custom method that must be written and there is no suggested
implementation.
In terms of creating a workflow instance:
For the WorkflowInstance class, there is only one documented constructor (although,
there are 2 constructors). This constructor indicates that a Hashtable Array of
Party properties is a parameter. The documentation doesn't tell us specifically
what goes in these Hashtables, though. And as for the second constructor, we have
no documentation and there is no mention in the API, but I do know that it takes
3 Strings as its parameters.
How do I start a public workflow within an application?
Thanks in advance,
Mark

Replace:
WorkflowInstance wi = startWorkflow();
with:
Hashtable[] array = new Hashtable[2];
Hashtable party1 = new Hashtable();
Hashtable party2 = new Hashtable();
party1.put(WorkflowInstance.PARTYNAME_KEY, PARTY_SOURCE);
party2.put(WorkflowInstance.PARTYNAME_KEY, PARTY_DEST);
array[0] = party1;
array[1] = party2;
WorkflowInstance wi = new WorkflowInstance(BUSINESS_PROCESS_NAME,
BUSINESS_PROCESS_MAJOR,
BUSINESS_PROCESS_MINOR,
BUSINESS_PROCESS_ROLE,
array);

Question on "How-to invoke a method once upon application start"

Hello everyone.
I'm trying to implement what the article "How-to invoke a method once upon application start" by Frank suggests.
https://blogs.oracle.com/jdevotnharvest/entry/how_to_invoke_a_method
Suppose that I'm having a single point of entry, so in my login.jpsx I have the below:
<f:view beforePhase="#{login.onBeforePhase}">In the method "onBeforePhase" I have to pass the phaseEvent, since the signature is the following:
public void onBeforePhase(PhaseEvent phaseEvent)but how do I know the phaseEvent when calling the login.onBeforePhase? How the call should be?
Thanks a lot!
ps. I'm using jDev 11.1.2.1.0

You need not pass anything to this method , this method will get called before every Phase except ReStore View
Just write the logic as Frank suggested for the phase in which you want the code to execute. You can get the PhaseId's like
PhaseId.RENDER_RESPONSE
public void onBeforePhase(PhaseEvent phaseEvent) {// from Frank's doc
//render response is called on an initial page request
if(phaseEvent.getPhaseId() == PhaseId.RENDER_RESPONSE){
... etc

Hi,
Call that method by instance of Subclass. OR
SUPER-->method.
Read very useful document
Constructors
Constructors are special methods that cannot be called using CALL METHOD. Instead, they are called automatically by the system to set the starting state of a new object or class. There are two types of constructors - instance constructors and static constructors. Constructors are methods with a predefined name. To use them, you must declare them explicitly in the class.
The instance constructor of a class is the predefined instance method CONSTRUCTOR. You declare it in the public section as follows:
METHODS CONSTRUCTOR
 IMPORTING.. [VALUE(]<ii>[)] TYPE type [OPTIONAL]..
 EXCEPTIONS.. <ei>.
and implement it in the implementation section like any other method. The system calls the instance constructor once for each instance of the class, directly after the object has been created in the CREATE OBJECT statement. You can pass the input parameters of the instance constructor and handle its exceptions using the EXPORTING and EXCEPTIONS additions in the CREATE OBJECT statement.
The static constructor of a class is the predefined static method CLASS_CONSTRUCTOR. You declare it in the public section as follows:
CLASS-METHODS CLASS_CONSTRUCTOR.
and implement it in the implementation section like any other method. The static constructor has no parameters. The system calls the static constructor once for each class, before the class is accessed for the first time. The static constructor cannot therefore access the components of its own class.
Pls. reward if useful....

Error while accessing a public method of applet from javascript.

Hi,
I am getting "Object doesn't support this property or method" error
when accessing a public method of applet from javascript in IE 6 using

The same is working in IE 7.
Thanks in advance.

I don't know why it happens, but this works for me in both versions:

Error when calling a Webservice's public method in Forms10g

Hi,
I'm getting the following error when calling a webservice's public method, i'm using Forms10g 10.1.2.3
java.rmi.RemoteException; nested exception is: HTTP transport error javax.xml.soap.SOAPException
java.security.PrivilegedActionException javax.xml.soap.SOAPException
Message send failed javax.net.ssl.SSLException SSL handshake failed X509CertChI have added the Jar containing the client proxy in both Classpaths(system variable and default.env), the jar has been made with jdk 1.4
I also have tested the client proxy from jDeveloper and it's working there, but in Forms i'm getting this error.
I guess my problem might be that i'm calling a webservice that is secured since the url starts with https
what should i do to fix this ??
Regards
Carlos

I understand, so i have a doubt, why the webservice works on jDeveloper ??Not just JDeveloper even soapUI and Neatbeans have a way of working without a client certificate installed.
I do not know how they achieve it. I know that they work without a client DC.
Cheers,
PS: See this http://stackoverflow.com/questions/8887434/webservices-ssl-https, it offers a clue.
The java programs run unhindered when one-way authentication is being used. These products ship with a digital certificate that is in the path of most popular CAs.
Corollary, if the Web Server is configured for mutual authentication then you need to install and configure the client certificate in the tools.

Calling Public Method in OOP.

Hello All,
How to call a Public method in one using the object of the other class.

Got the solution.

Accessing a private variable from a public method of the same class

can anyone please tell me how to access a private variable, declared in a private method from a public method of the same class?
here is the code, i'm trying to get the variable int[][][] grids.
public static int[][] generateS(boolean[][] constraints)
private static int[][][] sudokuGrids()
    int[][][] grids; // array of arrays!
    grids = new int[][][]
    {

Are you sure that you want to have everything static here? You're possibly throwing away all the object-oriented goodness that java has to offer.
Anyway, it seems to me that you can't get to that variable because it is buried within a method -- think scoping rules. I think that if you want to get at that variable your program design may be under the weather and may benefit from a significant refactoring in an OOP-manner.
If you need more specific help, then ask away, but give us more information please about what you are trying to accomplish here and how you want to do this. Good luck.
