Class IdentityHashMap.IdentityIterator

java.lang.Object
  java.util.IdentityHashMap.IdentityIterator

All Implemented Interfaces:: Iterator

Enclosing class:: IdentityHashMap

private class IdentityHashMap.IdentityIterator
extends java.lang.Object
implements Iterator

This class allows parameterized iteration over IdentityHashMaps. Based on its construction, it returns the key or value of a mapping, or creates the appropriate Map.Entry object with the correct fail-fast semantics and identity comparisons.

Field Summary

(package private) int count
          The number of elements remaining to be returned by next().

(package private) int knownMod
          The number of modifications to the backing Map that we know about.

(package private) int loc
          Location in the table.

(package private) int type
          The type of this Iterator: AbstractMap.KEYS 55 , AbstractMap.VALUES 55 , or AbstractMap.ENTRIES 55 .

Constructor Summary

(package private) IdentityHashMap.IdentityIterator(int type)
          Construct a new Iterator with the supplied type.

Method Summary

boolean hasNext()
          Returns true if the Iterator has more elements.

java.lang.Object next()
          Returns the next element in the Iterator's sequential view.

void remove()
          Removes from the backing Map the last element which was fetched with the next() method.
