Class LruObjectMap<K,V>

java.lang.Object

org.mini2Dx.gdx.utils.ObjectMap<K,V>

org.mini2Dx.core.collections.LruObjectMap<K,V>

Type Parameters:

K - The key type

V - The value type

All Implemented Interfaces:

java.lang.Iterable<org.mini2Dx.gdx.utils.ObjectMap.Entry<K,V>>

Direct Known Subclasses:

ConcurrentLruObjectMap

public class LruObjectMap<K,V>
extends org.mini2Dx.gdx.utils.ObjectMap<K,V>

Extends ObjectMap to implement least-recently used capabilities. Once the specified maximum capacity is reached, the key that has been used the least is removed from the map.
