Hello Everyone,

I am working an a small project in which we are interested in collecting
information about the method being advised. I looked in sample codes where
ASM packages is used. But I have a problem, in code below:

// .. some code
String[] args = new String[files.length + 1];
args[0] = "-emacssym";
for (int i = 0; i < files.length; i++) {
args[i + 1] = files[i].getAbsolutePath();
}
runMain(args, false);
}

public void runMain(String[] args, boolean useSystemExit) {
super.runMain(args, useSystemExit);
IProgramElement hierarchyRoot =
AsmManager.getDefault().getHierarchy().getRoot();
hierarchyRoot.walk(new MyHierarchyWalker());
}
and then in class MyHierarchyWalker I have the follwing:

public class MyHierarchyWalker extends HierarchyWalker{

public void preProcess(IProgramElement p) {

if (p.getKind().equals(IProgramElement.Kind.METHOD)) {

List relationships = AsmManager.getDefault().getRelationshipMap().get(p);
if (relationships != null){
for (Iterator it = relationships.iterator(); it.hasNext(); ) {
IRelationship relation = (IRelationship)it.next();

// .. some code}
}}

The problem is that "relationships" is null so I cannot do anything with
it. I checked it with different case studies all in AspectJ examples
package. For space war example the "relationships" is null but for
"Tracing Example" and "Telecomm Example" it is working and it gives all
the methods being advised.
Can any one tell me why it is working for one example and not for the
other?

THANKS A LOT

We did a major refactoring of how the project model is stored and created
for AJDT 1.6.1. A by product of this refactoring is making AsmManager no
longer a singleton. This means AsmManager.getDefault() is no longer the
proper method to call if you are in a multi-project setting (eg- eclipse).

Instead, you access the Asm through the compiler object. Take a look at
the AJDT core class org.eclipse.ajdt.core.model.AJProjectModelFacade,
particularly the init() method:

AjCompiler compiler =
AspectJPlugin.getDefault().getCompilerFactory().getCompilerF orProject(project.getProject());
AsmManager existingState = compiler.getModel();
if (existingState != null) {
relationshipMap = existingState.getRelationshipMap();
structureModel = existingState.getHierarchy();
if (relationshipMap != null && structureModel != null) {
isInitialized = true;
}
}

Hope this helps,

Hi Andrew,

Thanks for your quick answer. I don't know how can I give the project as
project.getProject(). I did as follows:

IPath pa=new Path("D://eclipse//Workspace//SpacewarExample");
Workspace w=new Workspace();
IProject p=new Project(pa, w);
AspectJPlugin.getDefault().getCompilerFactory().getCompilerF orProject(p);

but it is not working. How can I give the project for which I need to get
information to method getCompilerForProject(Project).

Thanks a lot,

Laleh

Try

ResourcesPlugin.getWorkspace().getRoot().getProject("foo");

Note that the path that you pass in is workspace relative.

Hello Andrew,

I tried what you proposed, the fact is that I am not building a plugin, I
have simple AspectJ project. when I used:

ResourcesPlugin.getWorkspace().getRoot().getProject("SpacewarExample ");

I got this exception:

Exception in thread "main" java.lang.IllegalStateException: Workspace is
closed.
at
org.eclipse.core.resources.ResourcesPlugin.getWorkspace(Reso urcesPlugin.java:320)
at ASMProcessor.runMain(ASMProcessor.java:30)
at ASMProcessor.processFiles(ASMProcessor.java:25)
at MainClass.main(MainClass.java:26)

Would you please help to handle the problem.

THANKS A LOT,

Laleh

I had assumed that since you were posting on the ajdt list that you were
using a plugin.

So, the way to grab hold of the AsmManager depends on how you are calling
the compiler. For example, if you can get access to the AjBuildManager,
call getState().getStructureModel().
