Interface ConcurrentMutableMap<K,V>

All Superinterfaces:

java.lang.Cloneable, java.util.concurrent.ConcurrentMap<K,V>, InternalIterable<V>, java.lang.Iterable<V>, java.util.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>, java.util.concurrent.ConcurrentMap<K,V>

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

Method Detail

tap

ConcurrentMutableMap<K,V> tap(Procedure<? super V> procedure)

Description copied from interface: MapIterable

Executes the Procedure for each value of the map and returns this.

 return peopleByCity.tap(person -> LOGGER.info(person.getName()));

getOrDefault

default V getOrDefault(java.lang.Object key,
                       V defaultValue)

Specified by:

getOrDefault in interface java.util.concurrent.ConcurrentMap<K,V>

Specified by:

withMap

default ConcurrentMutableMap<K,V> withMap(java.util.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>

Specified by:

withMap in interface MutableMapIterable<K,V>

See Also:

Map.putAll(Map)

withMapIterable

default ConcurrentMutableMap<K,V> withMapIterable(MapIterable<? extends K,? extends V> mapIterable)

Specified by:

withMapIterable in interface MutableMap<K,V>

Specified by:

withMapIterable in interface MutableMapIterable<K,V>

forEach

default void forEach(java.util.function.BiConsumer<? super K,? super V> action)

Specified by:

forEach in interface java.util.concurrent.ConcurrentMap<K,V>

Specified by:

forEach in interface java.util.Map<K,V>

Specified by:

merge

V merge(K key,
        V value,
        java.util.function.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).
