Class XLinkedHashMap.Entry<K,V>

java.lang.Object
  com.neeve.lang.XLinkedHashMap.Entry<K,V>

All Implemented Interfaces:

XCollection.Record, Map.Entry<K,V>

Enclosing class:

XLinkedHashMap<K,V>

public static class XLinkedHashMap.Entry<K,V>
extends Object
implements Map.Entry<K,V>, XCollection.Record

This class represents a XLinkedHashMap entry. Custom XLinkedHashMap may use a derived implementation. For example:[code] static class MyMap extends XLinkedHashMap { protected MyEntry newEntry() { return new MyEntry(); } class MyEntry extends Entry { X xxx; // Additional entry field (e.g. cross references). } }[/code]

Field Summary

static XLinkedHashMap.Entry<?,?>

NULL Holds NULL entries (to fill empty hole).
