Interface FixedSizeMap<K,V>

All Superinterfaces:

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

public interface FixedSizeMap<K,V>
extends MutableMap<K,V>

A FixedSizeMap is a map that may be mutated, but cannot grow or shrink in size.

Method Summary

Modifier and Type	Method	Description
void	clear()
V	put(K key, V value)
void	putAll(Map<? extends K,? extends V> map)
V	remove(Object key)
boolean	removeAllKeys(Set<? extends K> keys)	Remove entries from the map at the specified keys.
boolean	removeIf(Predicate2<? super K,? super V> predicate)	Remove an entry from the map if the predicate evaluates to true.
V	removeKey(K key)	Remove an entry from the map at the specified key.
FixedSizeMap<K,V>	tap(Procedure<? super V> procedure)	Executes the Procedure for each value of the map and returns this.
default FixedSizeMap<K,V>	withMap(Map<? extends K,? extends V> map)	Similar to Map.putAll(Map), but returns this instead of void
