Class SizeConstrainedMap<K,V>

java.lang.Object

net.lenni0451.commons.collections.maps.DelegateMap<K,V>

net.lenni0451.commons.collections.maps.SizeConstrainedMap<K,V>

Type Parameters:

K - The type of the keys in this map

V - The type of the values in this map

All Implemented Interfaces:

java.util.Map<K,V>

@NotThreadSafe
public class SizeConstrainedMap<K,V>
extends DelegateMap<K,V>

A map which is size constrained.
If more elements are added than the maximum size, the oldest elements will be removed.
This map is not thread safe.
