Re: [aspectj-dev] [ajdt structures]

[Adrian Colyer <adrian_colyer@xxxxxxxxxx>]

What you have here is a snippet that
uses the DOM to manipulate Java code. As explained in my previous post,
AspectJ only extends the core compilation AST at the moment, not the DOM,
so we don't support programmatic construction of AspectJ types in this
way yet. What features is your plugin implementing? There might be a way
we can help you to get what you need from the current code base...

(The ASTParser in your snippet below
is the org.eclipse.jdt.core.*dom*.ASTParser type - ie. it really is a DOM
type, the two trees use identical (unqualified) type names in many places
which can be very confusing at times...)

Subject	[aspectj-dev] [ajdt structures]

Hello everybody,
  I found in eclipse help (JDT Core > Manipulating Java Code) an
example of how to create an AST from scratch. The example is something
like the one below:

//------------------------------------------------
IDocument doc = new Document("import java.util.List;");
ASTParser parser = ASTParser.newParser(AST.JLS2);
parser.setSource(doc.get().toCharArray());
CompilationUnit cU = (CompilationUnit) parser.createAST(null);
cU.recordModifications();
AST ast = cU.getAST();
                
PackageDeclaration packageDeclaration = ast.newPackageDeclaration();
packageDeclaration.setName(ast.newSimpleName("exemplo"));
cU.setPackage(packageDeclaration);

TypeDeclaration type = ast.newTypeDeclaration();
type.setInterface(false);
type.setModifiers(Modifier.PUBLIC);
type.setName(ast.newSimpleName("HelloWorld"));
cU.types().add(type);

TextEdit edits = cU.rewrite(doc, null);
edits.apply(doc);
//------------------------------------------------

I´d like to do the same thing with the ajdt structures. Any thoughts?

Thanks!

Alexandre

}
}
//-----------------------

where cu is a CompilationUnit and the .java where the plugin runs is:

//-----------------------
public class HelloChild {
                
public void print(int x) {
                
                 System.out.println("Hello!
I´m a child! My number is: "+ x);        
                 
       
                
}
}

aspect World1 {
}
//-----------------------

I did it because the AspectDeclaration extends the TypeDeclaration
from jdt.core.dom. So, I supposed that I could get this element from a
.java file. Is this correct? Any thoughts?! Please, tell me if I´m
doing something stupid! My only itention is to get aspectj elements
from an open file editor.

Best regards!
