Method Detail

containsValue

public boolean containsValue(short v)

Specified by:

containsValue in interface Char2ShortMap

See Also:

Map.containsValue(Object)

containsValue

public boolean containsValue(Object ov)

Specified by:

containsValue in interface Map<Character,Short>

putAll

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

putAll in interface Map<Character,Short>

char2ShortEntrySet

public ObjectSet<Char2ShortMap.Entry> char2ShortEntrySet()

Description copied from interface: Char2ShortMap

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 Char2ShortMap.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:

char2ShortEntrySet in interface Char2ShortMap

Returns:

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

See Also:

Char2ShortMap.entrySet()

keySet

public CharSet keySet()

Description copied from interface: Char2ShortMap

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 Char2ShortMap

Specified by:

keySet in interface Map<Character,Short>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public ShortCollection values()

Description copied from interface: Char2ShortMap

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 Char2ShortMap

Specified by:

values in interface Map<Character,Short>

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<Character,Short>

entrySet

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

Description copied from interface: Char2ShortMap

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 Char2ShortMap

Specified by:

entrySet in interface Map<Character,Short>

Returns:

a set view of the mappings contained in this map.

Map.entrySet()

hashCode

public int hashCode()

Specified by:

hashCode in interface Map<Character,Short>

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Specified by:

equals in interface Map<Character,Short>

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
