# 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:
  `Get<K,V>`, `IterableGet<K,V>`, `IterableMap<K,V>`, `Map<K,V>`, `Put<K,V>`

All Known Implementing Classes:
  `FixedSizeMap`, `FixedSizeSortedMap`, `LRUMap`, `SingletonMap`

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:
