public static class Short2FloatMaps.EmptyMap
extends Short2FloatFunctions.EmptyFunction
implements Short2FloatMap, Serializable, Cloneable

An immutable class representing an empty type-specific map.

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

Method Detail

containsValue

public boolean containsValue(float v)

Specified by:

containsValue in interface Short2FloatMap

See Also:

Map.containsValue(Object)

putAll

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

Specified by:

putAll in interface Map<Short,Float>

short2FloatEntrySet

public ObjectSet<Short2FloatMap.Entry> short2FloatEntrySet()

Description copied from interface: Short2FloatMap

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 Short2FloatMap.entrySet() so that it returns an ObjectSet of objects of type Short2FloatMap.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

short2FloatEntrySet in interface Short2FloatMap

Returns:

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

See Also:

Short2FloatMap.entrySet()

keySet

public ShortSet keySet()

Description copied from interface: Short2FloatMap

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 Short2FloatMap

Specified by:

keySet in interface Map<Short,Float>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public FloatCollection values()

Description copied from interface: Short2FloatMap

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 Short2FloatMap

Specified by:

values in interface Map<Short,Float>

Returns:

a set view of the values contained in this map.

See Also:

Map.values()

containsValue

public boolean containsValue(Object ov)

Specified by:

containsValue in interface Map<Short,Float>

clone

public Object clone()

Overrides:

clone in class Short2FloatFunctions.EmptyFunction

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Map<Short,Float>

entrySet

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

Description copied from interface: Short2FloatMap

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 Short2FloatMap

Specified by:

entrySet in interface Map<Short,Float>

Returns:

a set view of the mappings contained in this map.

Map.entrySet()

hashCode

public int hashCode()

Specified by:

hashCode in interface Map<Short,Float>

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Specified by:

equals in interface Map<Short,Float>

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
