Class DeterministicHashMap

java.lang.Object
  java.util.AbstractMap<K,V>
      java.util.HashMap
          soot.util.DeterministicHashMap

All Implemented Interfaces:

Serializable, Cloneable, Map

public class DeterministicHashMap
extends HashMap

Implementation of HashMap which guarantees a stable (between executions) order for its elements upon iteration. This is quite useful for maps of Locals, to avoid nondeterministic local-name drift.
