Interface BoundedMap<K,V>

Type Parameters:

K - the type of the keys in this map

V - the type of the values in this map

All Superinterfaces:

IterableMap<K,V>, Map<K,V>

All Known Implementing Classes:

LRUMap, LRUMap

public interface BoundedMap<K,V>
extends IterableMap<K,V>

Defines a map that is bounded in size.

The size of the map can vary, but it can never exceed a preset maximum number of elements. This interface allows the querying of details associated with the maximum number of elements.

Since:

3.0
