Class AtomRef

java.lang.Object
  org.prorefactor.refactor.source.AtomRef

All Implemented Interfaces:

IAtom

public class AtomRef
extends java.lang.Object
implements IAtom

A reference to an Atom. When doing macro expansion, we often need a chain of atoms which is a bunch of fragmented sections from original source file(s). Rather than copy the atoms for macro expansion, we create references to the original atoms. To this end, we only need an object with a reference to the original atom, and this object's own next/prev attributes. All other attributes can come from the original Atom. Next and Prev must be other AtomRef objects - they cannot be Atom objects.
