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>, java.util.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.
