Re: Re: how to get the name of a local variable

Thank you.
But for the source code:
     Node node = new Node();
     node.key = data;
I can use the next code to get the name of "data".

     List locVars = mn.localVariables;
     ... ...
     LocalVariableNode locVar = (LocalVariableNode)locVars.get(var);
     String name = locVar.name;

but how about "node.key", now I can only get "key" from "GRTFIELD"
instruction.

Perhaps frame is useful, but how to get the current frame?
