Javaparser: How do i get the wrapper node from resolvedType

[f71uday]

After resolving a Name expression
and Loging the resolved object in below code snippet , log shows there is a object named wrapperNode inside resolved Node , how can I access that wrapperNode.

I didnt found any method in ResolvedValueDeclaration class which can take me to wrapper Node and If I missed any thing please guide me

 ResolvedValueDeclaration resolved = nameExpr.resolve();
               LOG.info(resolved);

LOG: JavaParserSymbolDeclaration{name='cmd', wrappedNode=cmd = "mkdir " + folder}

@MysterAitch It would be a great pleasure , if you help me resolve this issue.

I'm on mobile so can't check, but have you tried getParentNode or similar?

[f71uday]

ResolvedValueDeclaration class does not have any method like getParentNode

[jlerbsc]

If the declaration is associated to an AST node method toAst() returns it, otherwise it returns empty.

[MysterAitch]

As @jlerbsc mentions, the correct method is toAst() (I was wrong above, sorry!).

An example of this is ResolvedFieldDeclaration which extends AssociableToAST<FieldDeclaration> (AssociableToAST gives the toAst() method)

Looking a bit more closely, I don't see anything similar for NameExpr speficially. The screenshot below shows some classes that do implement it. Are you able to make use of any of these @f71uday ?

[MysterAitch]

Sidenote: I'm not sure whether NameExpr _should_ be associable to the AST -- I don't immediately see why not (other than not having a wrappedNode field), but I've been away for a while and there might be a really obvious reason this is the case!

Edit: scratch that -- the NameExpr itself shouldn't have it.

Instead, the thing that the name expr represents should implement it (e.g. if it's a field, or an enum, or a declaration, or a class or a package, or whatever... THAT should implement it).

Consider the following example for how this works in practice:

    ResolvedValueDeclaration resolvedValueDeclaration = new NameExpr().resolve();
    if(resolvedValueDeclaration.isField()) {
        Optional<FieldDeclaration> fieldDeclaration = resolvedValueDeclaration.asField().toAst();
    } else if(resolvedValueDeclaration.isMethod()) {
        Optional<MethodDeclaration> methodDeclaration = resolvedValueDeclaration.asMethod().toAst();
    } else if(/*...*/) {
        /*...*/)
    }

@MysterAitch

i tried below code and it help me getting me wrapperNode
JavaParserParameterDeclaration resolvedType = (JavaParserParameterDeclaration)nameExpr.resolve(); Node a= resolvedType.getWrappedNode();

However i tried your solutions as well , both are working ,

Raising an issue and talking to community about the issue always helps gathering more knowledge.
Thank you @MysterAitch @jlerbsc .
