Class IInstanceVariableVisitor

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

All Implemented Interfaces:

NodeVisitor

public class IInstanceVariableVisitor
extends NoopVisitor

To use this visitor pass in the root of the scope you want to search for instance variables. This will not enter into contained classes/modules/singleton-classes so it should not see same-named ivars in a nested class. If you want those as well it is up to you to realize the ivars in those nested objects refer to the same instance variables and you need to visit them separately.

Constructor Summary

IInstanceVariableVisitor(Node root, String name)

Method Summary

static List<IInstanceVariable>	findOccurrencesIn(Node root, String name) This helper method uses Node instead of IModuleScope so that you can do more localized searching (e.g.
List<IInstanceVariable>	getVariableList()
void	run()
Object	visitClassNode(ClassNode iVisited)
Object	visitInstAsgnNode(InstAsgnNode iVisited)
Object	visitInstVarNode(InstVarNode iVisited)
Object	visitModuleNode(ModuleNode iVisited)
Object	visitSClassNode(SClassNode iVisited)

Constructor Detail

IInstanceVariableVisitor

public IInstanceVariableVisitor(Node root,
                                String name)

Method Detail

findOccurrencesIn

public static List<IInstanceVariable> findOccurrencesIn(Node root,
                                                        String name)

This helper method uses Node instead of IModuleScope so that you can do more localized searching (e.g. all instance variables in a method).
