How to gain access to "this" variable in INRIA-SPOON

Question

I'm working with INRIA Spoon.

I have some dynamic methods invocations like the following one:

a.doSomething();

I can obtain to the variable access a using the getTarget() method of the CtInvocation instance. My task is to generate code to store a into file. To do so, I need the type and source position (class name, line, etc) of a so I can generate code like logger.logSerializable(a, "My.Class:21") or like logger.logDoubleArrayList(a, "My.otherClass:23)".

So far so good, I managed to do this just fine by acquiring the result of the getTarget method of a CtInvocation instance. However, when the invocation's target is equal this, like for example:

doSomething(); // equivalent to -> this.doSomething();

the getTarget returns null.

How can I get the this variable access one given CtInvocation is targeting?

Answer 1

By looking for targets (getTarget) instance of CtThisAccess or by directly processing CtThisAccess
