Method Detail

create

<K,V> ConcurrentMap<K,V> create()

This method creates a new Map instance.
It is explicitly typed and respects the generic key and value type of the map. Therefore the type of the Map can NOT be bound to the generic type <MAP> because of limitations in Java's generic type system. You need to work on the actual sub-interface (e.g. SortedMapFactory) to get a more specific result type.

Specified by:

create in interface MapFactory<ConcurrentMap>

Type Parameters:

K - the type of keys maintained by the map.

V - the type of mapped values.

Returns:

the new map instance.

create

<K,V> ConcurrentMap<K,V> create(int capacity)

This method creates a new Map instance with the given capacity. For a regular map this will be the initial capacity while a cache may never grow beyond this capacity limit and if reached force out entries last recently of frequently used.

Specified by:

create in interface MapFactory<ConcurrentMap>

Type Parameters:

K - the type of keys maintained by the map.

V - the type of mapped values.

Parameters:

capacity - is the capacity of the map to create.

Returns:

the new map instance.
