Re: [jdt-dev] get name of the anonymous class

[Alex Lovkov <charmik1994@xxxxxxxxx>]

I just tried all methods which return something:) 

I read in docs: that if I don't use java-plugin, I can specify ASTParser by unitName and Environment, but it didn't help me at all. .getJavaElement returns null anyway, from your code. So how can I get real name of anonymous class? Like Main$1$2 for example? Is it really possible? Thanks!

I am surprised it returned non null for a source file. I thought the getBinaryName() will return
anything meaningful only for elements loaded as binaries.

I got name of the anonymous class by this: 
@Override
public boolean visit(AnonymousClassDeclaration node) {
ITypeBinding resolveBinding = node.resolveBinding();
String binaryName = resolveBinding.getBinaryName();
return true;
}
but it gives me wrong name for inner anonymous classes, example:
new Serializable() {
void x() {
new Serializable() {
};
}
};
it prints Main$1 Main$2, but it should be Main$1 and Main$1$1.
I get .getJavaElement()=null anyway. Can I fix it without ecpilse plugin? Thanks!

One way of achieving that is by using Java model elements, like below:

@Override
public boolean visit(AnonymousClassDeclaration node) {
ITypeBinding resolveBinding = node.resolveBinding();
IType javaElement = (IType) resolveBinding.getJavaElement();
System.out.println(javaElement.getFullyQualifiedName());
return true;
}

Hello, I was wondering how can I get the name of the anonymous class (exactly "$1", or Main$1) from AST, after I parse my source file?
If I try to get the name of the class going recursive to the root from the variable, I don't get FieldDeclaration -> TypeDeclaration as in normal (Z) class, I get the next one: FieldDeclaration -> AnonymousClassDeclaration -> ClassInstanceCreation
and AnonymousClassDeclaration doesn't have any getName() methods. 
So how can I get "$1" by AnonymousClassDeclaration/ClassInstanceCreation? thanks!

example:
public class Main {
void f() {
new Serializable() {
public static final String T1 = "T1";
};
}
private class Z implements Serializable {
public static final String T2 = "T2";
}
}
ASTParser parser = ASTParser.newParser(AST.JLS11);
parser.setKind(ASTParser.K_COMPILATION_UNIT);
parser.setSource(new String(Files.readAllBytes(Paths.get(
"src/main/java/Main.java"))).toCharArray());
CompilationUnit unit = (CompilationUnit) parser.createAST(new NullProgressMonitor());

ArrayList<FieldDeclaration> fields = new ArrayList<>();
unit.accept(new ASTVisitor() {
@Override
public boolean visit(final FieldDeclaration node) {
fields.add(node);
return super.visit(node);
}
});
FieldDeclaration fieldDeclaration_T1 = fields.get(0);
FieldDeclaration fieldDeclaration_T2 = fields.get(1);
ASTNode T1parent = fieldDeclaration_T1.getParent(); //AnonymousClassDeclaration here (can't get $1)
ASTNode T2parent = fieldDeclaration_T2.getParent(); //TypeDeclaration here. can use .getName() to get a name of nested class) cl
