Class SubstituteRefactor

java.lang.Object
  org.prorefactor.refactor.substitute.SubstituteRefactor

All Implemented Interfaces:

IConstants

public class SubstituteRefactor
extends java.lang.Object
implements IConstants

Given a handle to a PLUS node, where multiple PLUS and QSTRING nodes are used, changes the AST to use SUBSTITUTE, and synchronizes the scanner's token list.

Current implementation changes the AST, with no option to rollback the changes. (i.e. If the changes are rejected by the client, then the AST should be rebuilt (re-parse the compile unit) before using it for anything else.) See notes at top of SubstituteRefactor.java.
