Class MapEntrySet<K,V>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractSet<E>

java.util.HashSet<E>

java.util.LinkedHashSet<Entry<K,V>>

de.tsl2.nano.collection.MapEntrySet<K,V>

All Implemented Interfaces:

Serializable, Cloneable, Iterable<Entry<K,V>>, Collection<Entry<K,V>>, Set<Entry<K,V>>

public class MapEntrySet<K,V>
extends LinkedHashSet<Entry<K,V>>

Combines the interfaces of List and Map. The underlying instance is a map - the list will hold the maps entries Map.entrySet().

Problem: It is not possible to create a class implementing both interfaces of List and Map. There is an interface name-clash on the remote(Object) method.
Errormessages: The return types are incompatible for the inherited methods Map.remove(Object), LinkedList>.remove(Object)

Map.Entry is not serializable!
