Interface Char2ObjectMap<V>

All Superinterfaces:

Char2ObjectFunction<V>, Function<Character,V>, Map<Character,V>

All Known Implementing Classes:

AbstractChar2ObjectMap, Char2ObjectOpenHashMap

public interface Char2ObjectMap<V>
extends Char2ObjectFunction<V>, Map<Character,V>

A type-specific Map; provides some additional methods that use polymorphism to avoid (un)boxing, and handling of a default return value.

Besides extending the corresponding type-specific function, this interface strengthens entrySet(), keySet() and values(). Maps returning entry sets of type Char2ObjectMap.FastEntrySet support also fast iteration.

A submap or subset may or may not have an independent default return value (which however must be initialized to the default return value of the originator).

Method Detail

entrySet

ObjectSet<Map.Entry<Character,V>> entrySet()

Returns a set view of the mappings contained in this map.

Note that this specification strengthens the one given in Map.entrySet().

Specified by:

entrySet in interface Map<Character,V>

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

char2ObjectEntrySet

ObjectSet<Char2ObjectMap.Entry<V>> char2ObjectEntrySet()

Returns a type-specific set view of the mappings contained in this map.

This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen entrySet() so that it returns an ObjectSet of objects of type Map.Entry (the latter makes it possible to access keys and values with type-specific methods).

Returns:

a type-specific set view of the mappings contained in this map.

See Also:

entrySet()

keySet

CharSet keySet()

Returns a set view of the keys contained in this map.

Note that this specification strengthens the one given in Map.keySet().

Specified by:

keySet in interface Map<Character,V>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

ObjectCollection<V> values()

Returns a set view of the values contained in this map.

Note that this specification strengthens the one given in Map.values().

Specified by:

values in interface Map<Character,V>

Returns:

a set view of the values contained in this map.

Map.values()
