Class ILocalVariableVisitor

java.lang.Object
  org.jrubyparser.util.NoopVisitor
      org.jrubyparser.util.ILocalVariableVisitor

All Implemented Interfaces:

NodeVisitor

public class ILocalVariableVisitor
extends NoopVisitor

Find all ILocalVariables for a particular scope. The implementation will walk all children until it runs into a nested scope which cannot possibly be in the current scope (e.g. a def in a def). IterNode is the lone IScope which can capture external ILocalVariables so we let the visitor enter into them. Restricting this walking is meant as an optimization since our logic will only allow variables of the same scope to be added to the list.
