public class AliasGroup

extends java.util.HashSet

This is the class that represents the set of HIR nodes which may be aliased to a given HIR node. Objects that elements of this set represent and the object the HIR node that owns this set represents possibly share some subspace in the memory space. A CONTENTS node with uninitialized pointer value operand is considered to represent an object that does not inhabit the memory space, so its associated AliasGroup object is empty (even does not contain the CONTENTS node itself).

Currently does not expose any public/protected fields/methods except the ones inherited from HashSet.
