public static class Int2CharMaps.Singleton
extends Int2CharFunctions.Singleton
implements Int2CharMap, Serializable, Cloneable

An immutable class representing a type-specific singleton map.

This class may be useful to implement your own in case you subclass a type-specific map.

Method Detail

containsValue

public boolean containsValue(char v)

Specified by:

containsValue in interface Int2CharMap

See Also:

Map.containsValue(Object)

containsValue

public boolean containsValue(Object ov)

Specified by:

containsValue in interface Map<Integer,Character>

putAll

public void putAll(Map<? extends Integer,? extends Character> m)

Specified by:

putAll in interface Map<Integer,Character>

int2CharEntrySet

public ObjectSet<Int2CharMap.Entry> int2CharEntrySet()

Description copied from interface: Int2CharMap

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 Int2CharMap.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).

Specified by:

int2CharEntrySet in interface Int2CharMap

Returns:

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

See Also:

Int2CharMap.entrySet()

keySet

public IntSet keySet()

Description copied from interface: Int2CharMap

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 Int2CharMap

Specified by:

keySet in interface Map<Integer,Character>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public CharCollection values()

Description copied from interface: Int2CharMap

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 Int2CharMap

Specified by:

values in interface Map<Integer,Character>

Returns:

a set view of the values contained in this map.

See Also:

Map.values()

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Map<Integer,Character>

entrySet

public ObjectSet<Map.Entry<Integer,Character>> entrySet()

Description copied from interface: Int2CharMap

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 Int2CharMap

Specified by:

entrySet in interface Map<Integer,Character>

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

hashCode

public int hashCode()

Specified by:

hashCode in interface Map<Integer,Character>

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Specified by:

equals in interface Map<Integer,Character>

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
