Replace Vi's in Class (Member)

HI
What is the best way to replace a vi in a LVClass?
Urs Müller

Maybe I don't understand the question. From this I assume you want a new VI with the same name as an existing one. Just right click the old one and select remove from library. Now create your new vi and save it under the old name and select overwrite. You might want to first move the old one on disk if you think you will need it again. You need to use the library editor window. You cannot just use the OS file manager because that will not make the new VI a member of the class.

Pass C++ Class Member Function as a callable function in AIR Native Extension

I'm writing an ANE and I'd like to know if anyone has been able to pass a C++ class member function pointer as a callable function from AIR? I have tried this so far with a little bit of C++11 trickery and it's crashing. I've also statically linked the libstdc++ into my library, according to the documentation, in order to ensure that these features I use work correctly. I have code like so:
FakeWorld* world = new FakeWorld();
*numFunctions = 1;
memberFunctions = (FRENamedFunction*) malloc(sizeof(FRENamedFunction) * (*numFunctions));
ANEMemberFunction mCreateFakeBody = std::tr1::bind(&FakeWorld::createFakeBody, world, std::tr1::placeholders::_1, std::tr1::placeholders::_2, std::tr1::placeholders::_3, std::tr1::placeholders::_4);
ANEFunction* createFakeBody = mCreateFakeBody.target<ANEFunction>();
memberFunctions[0].name = (const uint8_t*) "createFakeBody";
memberFunctions[0].functionData = NULL;
memberFunctions[0].function = createFakeBody;
FRESetContextNativeData(ctx, (void*)world);
I just realized I'm using C here for allocating the member functions array.. silly me, but I don't think this is the cause of my issue. I refuse to believe that Adobe has built to the Native Extensions portion of the runtime in such a way that I have to cram every single function I want to create (natively) into a global, C formatted namespace (Especially since the documentation says that C is only required for the extenion and context initializing function interfacing and the rest of the code can be done in C++ or objective-C). So please let me know if and how this is possible and I thank you so much in advance for your time!P.
P.S. Currently when I run this code, I can do the object initialization just fine. As soon as I invoke the "createFakeBody" method on the native side, the runtime dies and simply says:

Thanks again for your assitance.

It's been a little while since i've dealt with C++ and not up to speed on tr1 or C++0x, so forgive me if i'm not helping.
The the examples of std::tr1::bind that i'm seeing out there seem to be either dereferencing the bound 'this' pointer when creating the bound method, i.e. in your case *world instead of world, or using std::tr1::ref(*world), therefore i believe that bind expects the bound parameters to be passed by reference.
Given that the result of std::tr1::bind is callable (basing that on http://stackoverflow.com/questions/3678884/virtual-member-functions-and-stdtr1function-how -does-this-work) could you simplify to the following:
memberFunctions[0].name = (const uint8_t*) "createFakeBody";
memberFunctions[0].functionData = NULL;
memberFunctions[0].function = std::tr1::bind(&FakeWorld::createFakeBody, *world, std::tr1::placeholders::_1, std::tr1::placeholders::_2, std::tr1::placeholders::_3, std::tr1::placeholders::_4);
Or for an even simpler starting point, creating a test member function 'helloWorld' in FakeWorld that takes no arguments and using:
memberFunctions[0].name = (const uint8_t*) "helloWorld";
memberFunctions[0].functionData = NULL;
memberFunctions[0].function = std::tr1::bind(&FakeWorld::helloWorld, *world);
Hope this helps.

Class/member variables usage in servlets and/or helper classes

I just started on a new dev team and I saw in some of their code where the HttpSession is stored as a class/member variable of a servlet helper class, and I was not sure if this was ok to do or not? Will there be problems when multiple users are accessing the same code?
To give some more detail, we are using WebLogic and using their Controller (.jpf) files as our servlet/action. Several helper files were created for the Controller file. In the Controller, the helper file (MyHelper.java) is instantiated, and then has a method invoked on it. One of the parameters to the method of the helper class is the HttpServletRequest object. In the method of the helper file, the very first line gets the session from the request object and assigns it to a class variable. Is this ok? If so, would it be better to pass in the instance of the HttpServletRequest object as a parameter to the constructor, which would set the class variable, or does it even matter? The class variable holding the session is used in several other methods, which are all invoked from the method that was invoked from the Controller.
In the Controller file:
MyHelper help = new MyHelper();
help.doIt(request);MyHelper.java
public class MyHelper {
    private HttpSession session;
    public void doIt(HttpServletRequest request) {
        session = request.getSession();
        String temp = test();
    private String test() {
        String s = session.getAttribute("test");
        return s;
}In the past when I have coded servlets, I just passed the request and/or session around to the other methods or classes that may have needed it. However, maybe I did not need to do that. I want to know if what is being done above will have any issues with the data getting "crossed" between users or anything of that sort.
If anyone has any thoughts/comments/ideas about this I would greatly appreciate it.

No thoughts from anyone?

I'm looking at the property bpm. It isn't a class variable. I'm confused why this is... does it still work like the other class variables? I see that the the getter and setter methods are implemented rather than synthesized... But I still don't understand why it isn't a class member...
Thanks.

First, in Objective-C there is no "class member", only instance variable (and no class variable).
Second, @property allows you to declare accessor methods without writing those :
- (void)setName:(NSString *)aName;
- (NSString *)name;
That's just some line economizing.
On the implementation side. @synthesize allows you to implement methods without writing those :
- (void)setName:(NSString *)aName {
if(name != aName)
[name release];
name = [aName retain];
- (NSString *)name {
return [[name retain] autorelease];
Here it economize code again... Nothing more.
@synthesize creates a default implementation for a specific property. However if you want to make specific modifications in your getter/setter you're forced to implement the methods yourself. In this case the reason is that there's no bpm ivar to link the properties to.
But it could be another possibility, like, for example, when the user set the name, you want a nick-name ivar to be set as well. Here you need to use a specific method implementation and @synthesize can't help you.
However, that are just implementation things... It doesn't change the behavior of the properties... And you can even use the dot-syntax on non-property methods if you want, it's just need to be KVC-compliant.

Toplink Unmapped class member in Entity

I am using Oracle Toplink
I would like to add an unmapped property (class member) to my entity, meaning I just want an entity class member that is not tied to the database. Doing so, toplink automatically defaults the mapping and throws an exception stating that no database column exists. I just want a simple class member that does not exist in the database.
Is it possible to tell toplink to ignore this class member so that it will not look for it in the database?
What are the alternatives?
Thanks for the help
Suzanne

You need to mark the field as transient using the JPA @Transient annotation.

Reference to Class Member Functions

Hello all.
I have a question about references to LV class member functions. I have a small example to demonstrate my problem.
My test class Base implements a reentrant public dynamic dispatch member function, doSomething.vi.
Another test class, Child, inherits Base and overrides the implementation of doSomething.vi.
Now say I have an array of Base objects (which could include any objects from classes that inherit Base). I want to run the doSomething methods for all the objects in the array in parallel.
In C++, I'd define a pointer to the virtual member function doSomething, and use it with each object in the array and the correct version of doSomething would be called.
In Labview, the only way I've found to do it is like this:
This is less than ideal, because it relies on every child class implementing doSomething, and relies on specific names for the inputs to the method.
Is there a better way to do this?
Thank you,
Zola

I still suspect you are over-working this code and not leting LVOOP do tis thing.
As I understand it you want to creae an active object but detemine its class at run time. The recent Architect summit touched on messaging for what they are calling a "worker Pool" pattern or what-not. YOu may want to search on the summit stuff. lacking that I'll share some images of where I did something similar ( I think). Note this is an older app and new stuff like the "Start Asyncronous call..." has been introduced making this even easier.
I want to create a new Active Object (thread running in the background) so I invoke a method to do so
It invokes the following that create some queues for talking to it and getting info back.
Time does not permit me doing a complete write-up but I have assembled the above images into a LVOOP Albumn found here.
When you click on one of those images you will get a large view as shown in this example.
Just below that image you will find a link to the original thread where I posted the image and talked about it.
I believe the best I can do for you at the moment is to urge you to browse my albumn and chase the links.
That agllery was assembled in an attmept to help you and other before you asked. I hope it is helpful.

In your lab05, replace instructor's Tokenizer class and MyStackQueue packag

Objective:
The objective of this lab is to get you some experience in processing strings character by
character and in implementing stacks and queues in a class package.
The programming assignment:
In your lab05, replace instructor’s Tokenizer class and MyStackQueue package with your own.
Requirements:
1. You must use an array to implement your queue.
2. You must use a linked list to implement your stack.
3. You must use the following frame work to implement your tokenizer.
class Tokenizer {
private char [] Buf;
private int cur;
Tokenizer(String infixExpression) {
Buf = infixExpression.toCharArray();
cur = 0;
Token nextToken() {
1. Skip blanks.
2. if (cur>=Buf.length) return null;
3. If the next character is a digit, keep reading until a non-digit is read.
Convert the string of digits into an integer.
String Digits = new String(Buf, start, len);
int num = Integer.valueOf(Digits).intValue();
Create and return an operand.
4. Otherwise, use the next character to create and return an operator.
class Tokenizer {
     private char[] Buf;
     private int cur;
     Tokenizer(String infixExpression) {
          Buf = infixExpression.toCharArray();

Static class member is beying destroyed inside a Controller - Why?

Hello,
I need to manage a certain BigDecimal class member in a Dynpro application which will not be destroyed. This class member represents a key in a database which from few reasons I would like to manage on my own.
In order to implement that, I have created a private static class member at the Controller and a get method in order for the other views to get it's value.
The get method checks if the value is null.
In case it is it queries the Database for the maximum value and return it + 1 to the requestor.
In case it is not null it simply increments the current value by 1 and returns it to the requestor.
According to my assumption, a DB query should happen only once since this member is static, yet when I monitor the application I see it queries the Database occasionally, which mean that the member has been destroyed.
I tried solving that by setting the expirationTime of the application to few hours but even inside this range the variable is being destroyed.
My questions are:
1. What am I missing here?
2. How and where should I manage a static variable in a Web dynpro application in order to assure it won't be destroyed during the lifetime of the application?

Hello Valery,
Here is the relevant code:
At the controller I declare this static member:
private static BigDecimal globalRequest = null;
And here is the method:
public java.lang.String getNewRequestNumber( java.sql.Statement statement )
    //@@begin getNewRequestNumber()
    try
          if (globalRequest == null)
               ResultSet rs = statement.executeQuery("SELECT MAX(record_number) AS maxRecord FROM COMMITTEES_REQUEST");
               if (rs.next())
                    BigDecimal maxRequest = rs.getBigDecimal("maxRecord");
                    globalRequest = maxRequest.add(new BigDecimal(1));
                    rs.close();
                    return (globalRequest.toString());
               else
                    rs.close();
                    return null;
          else
               globalRequest = globalRequest.add(new BigDecimal(1));
               return (globalRequest.toString());
    catch (SQLException e)
         return null;
    //@@end
Thank you in advance,
Roy

Dynamically start class member vi (non blocking)

Hi folks,
I've got a problem.
I thought about building a framework, where i can dynamically start modules based on one class.
The inherited classes representing the modules shold have a class member vi, that (containing a while loop) can be started dynamically.
All selectes modules should be started from a loop starting one module after the other. Thus the dynamically start needs to be non blocking.
I tried several ways, but allways reached the point, where the OOP approach limits the dynamically execution.
Has anyone done something similar and can tell me how/if this is possible?
Thanks in advance.
Best regards,
Balze

Have a look at this link:
http://lavag.org/topic/15035-lapdog-messaging-and-actor-framework/
Or this:
http://lavag.org/topic/14600-self-addressed-stamped-envelopes/
On lavag.org there are a lot of discussion on that type of framework. There are a whole section for OOP, try to see if anything help you.
Look for Actor Framework or LapDog.
Some talk alot on messages between loops, but that is to control free runing loops/vi's.
Hope this helps.

Binding function pointer to class member fnction

Creating a class member VI from a template locks the class library.

I have a LabVIEW (8.6.1) class where I need to create a number of very similar member VI's. In order to make this process more convenient, I created a couple of VI templates. However, I've found that creating a new VI from the template always locks the class library. The library then remains locked until I close and reopen the project.
When I select "Why is library locked?" from the context menu, I'm told:
"The library is locked because: This LabVIEW class is loaded in multiple application instances. Classes must be in only a single application instance to be edited. The containing library is locked."
I have the same problem if I create a new project (see attached ZIP file), add a class, and then add two templates. Everything seems OK if I have only one template.
Am I doing something wrong, is this a bug in LabVIEW, or do I misunderstand the expected/intended behavior of template VI's? Is there a way to "unlock" the class library without closing and reopening the project?
Thanks in advance,
Mark Moss

Accessing Class Member Vars From Flash?

Hi,
I'm writing an audio intensive application that requires a lot of data manipulation on the Alchemy side and I ran into a wall with my approach.
I'm using C++ to initialize a Class and populate its members in the "Alchemy-side" of the project. However, to keep things tidy and fast, I wish to write some audio data to a Float Array member of the class directly from Flash to avoid redundant copying.
If this seems strange, I have done it successfully for a Float Array defined in the main C (or C++) file and passed a pointer back to AS3 so that the "shared memory" could find the precise location in memory and read/write:
Setting up shared memory:
               var ns:Namespace = new Namespace("cmodule.cppPackage");
               cRAM = (ns::gstate).ds;
               libLoader = new CLibInit();
               lib = libLoader.init();
where cRAM is a byteArray I used and is associated with the shared memory. cRam,position = DataPtr would get me access to the data I want
However, this approach hasn't proven fruitful for Data Arrays located within a class. Here is a quick look at my class implementation:
class AudioChannel {
private:
     int fs, frameSize;
     bool fftComputed;
public:
     float *audioFrame, *fftFrame;
     int *intArr;
     int stuff;
     AudioChannel();                                             //default constructor
     ~AudioChannel();
     void initChannel(int fSize, int sampleRate);     //initializes the paramters
     int getSampleRate();
     int getFrameSize();
the audioFrame array is allocated and initialized in the "intiChannel" method, and it has public access. From the main .cpp file I simply return &(ch.audioFrame), (ch is the object instance) as an AS3_Ptr so I can use that to find the data.
The way in which I attempt to access the values in AS3 is as follows:
               cRAM.position = chAudPtr;
               for(var i:int = 0; i < 25; i++ ) {
                    cRAM.position = chAudPtr + sizeofFloat*i;
                    var tempVal:int = cRAM.readFloat();
                    trace('the tempVal is : ' + tempVal);
The problem is, that the function returns the wrong values. chAudPtr is the address for the "audioFrame" member in the C++ class I defined earlier and the initChannelMethod initialized the first 25 values to 0 through 24. I confirmed this with trace statements in the C code. Furthermore, when I try to write to this memory, I receive:
RangeError: Error #1506: The specified range is invalid
Is this some sort of limitation of Alchemy with data structures (classes, structs, etc)?. The strange thing is I can read and write the primitive members of the class with no issues (i.e. "stuff, fs, frameSize") using the above methods. But I can't seem to get it to work right with arrays in the object.
Any tips are appreciated, I'm trying to create something really clean and self-contained.
Thanks.

sorry about the &nbsp. you can ignore that...some weird formatting thing for the code-style formatting....

Assigning a value to a class member

I need to use reflection, and I cant set the value of an attribute of the class of type string;
Class Song{
string Author;
Class Test{
Song song = new Song();
String myAuthor= "Kim"
song.getClass().getDeclaredField().getName("Author").set?????(song, myAuthor);
Edited by: andromaque on Aug 13, 2008 6:10 AM

I should create getters/setters in the Song class. Example:
public class Song {
    String Author;
    public String getAuthor() {
        return Author;
    public void setAuthor(final String author) {
        Author = author;
    public static void main(final String[] args) {
        final Object o = new Song();
        final String author = "Kim";
        try {
            o.getClass().getMethod("setAuthor", String.class).invoke(o, author);
        } catch (final Exception e) {
            e.printStackTrace();
        // try if it succeed
        System.out.println("Author: " + ((Song) o).getAuthor());
}Output:
Author: Kim

Retrieving class member list out of source file.

Hi, all.
I got stuck to do this.
I want to retreive list of class members' name.
For example,
class Testing{
int var1;
List var2;
InnerTest var3;
void method1{ }
public void method2{ }
private int method3{}
class InnerTest{
int varInner1;
my expected out put:
class: Testing
instance vars: var1, var2, var3
method: method1, method2, method3
inner class: InnerTest
instatnce vars(Inner): varInner1
How can I do this? I don't have any idea yet.
source code can be any kinds of valid source code file.
If any one have any idea of this or any examples of this, please post it. It will be big help.
Thank you.

Thank you for the answer.
But, that's possible during run time.
I want to do it in Editing time.
It's like this;
when you editing your java source with editor tool like forte or JCreator.., the editor shows the list of class, methods and instance variables.
I want to know how this job is done.
Please answer, this is big stuck to me for my project.
Thank you.

AspectJ usage for compilation error on field/class Member type

Hello,
I have stuck up with impleamentation of functionality to achieve following-
I have class ABC and have multiple members in that. I want to give compiler error if the field type is List or non-primitive. I am trying this with AspectJ. But could not accomplish the task. Can somebody please suggest me some method or way to get this done ?
Thanks.

Can somebody please suggest me some method or way to get this done ?Yes, that kind of check pretty straightforward to implement with an annotation processor.
I suggest using JDK 6 and javac for this task. To get started, see the packages javax.annotation.processing and javax.lang.model.*; also the JDK comes with an example checker in
sample/javac/processing/src/CheckNameProcessor.java

Replace Vi's in Class (Member)
