Interface ConcurrentMutableMap<K,V>

All Superinterfaces:

Cloneable, ConcurrentMap<K,V>, InternalIterable<V>, Iterable<V>, Map<K,V>, MapIterable<K,V>, MutableMap<K,V>, MutableMapIterable<K,V>, RichIterable<V>, UnsortedMapIterable<K,V>

All Known Implementing Classes:

ConcurrentHashMap, ConcurrentHashMapUnsafe, ConcurrentMutableHashMap

public interface ConcurrentMutableMap<K,V>
extends MutableMap<K,V>, ConcurrentMap<K,V>

A ConcurrentMutableMap provides an api which combines and supports both MutableMap and ConcurrentMap.

Modifier and Type	Method	Description
default void	forEach(BiConsumer<? super K, ? super V> action)
default V	getOrDefault(Object key, V defaultValue)
V	merge(K key, V value, BiFunction<? super V, ? super V, ? extends V> remappingFunction)	A concurrent implementation of ConcurrentMap.merge(Object, Object, BiFunction) and Map.merge(Object, Object, BiFunction).
ConcurrentMutableMap<K,V>	tap(Procedure<? super V> procedure)	Executes the Procedure for each value of the map and returns this.
default ConcurrentMutableMap<K,V>	withMap(Map<? extends K, ? extends V> map)	Similar to Map.putAll(Map), but returns this instead of void

withMap

default ConcurrentMutableMap<K,V> withMap(Map<? extends K, ? extends V> map)

Description copied from interface: MutableMapIterable

Similar to Map.putAll(Map), but returns this instead of void

Specified by:

withMap in interface MutableMap<K,V>

merge

V merge(K key,
 V value,
 BiFunction<? super V, ? super V, ? extends V> remappingFunction)

A concurrent implementation of ConcurrentMap.merge(Object, Object, BiFunction) and Map.merge(Object, Object, BiFunction). In the implementing classes, it is possible for the remappingFunction to be called multiple times. It is also possible for the remappingFunction to be called one or more times, but the result is not used (because the old entry was concurrently removed).
