Class ScopeHidingVariableRewriter

java.lang.Object

org.benf.cfr.reader.bytecode.analysis.opgraph.op4rewriters.ScopeHidingVariableRewriter

All Implemented Interfaces:

Op04Rewriter

public class ScopeHidingVariableRewriter
extends Object
implements Op04Rewriter

We may have deep inner classes, with references to each other.

So

this.Inner2.this.Inner1.this

But this is illegal. So remove the outer one, leaving

this.Inner1.this (the LHS this is still illegal, but will be removed later).
