public static class Long2FloatMaps.Singleton
extends Long2FloatFunctions.Singleton
implements Long2FloatMap, 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(float v)

Specified by:

containsValue in interface Long2FloatMap

See Also:

Map.containsValue(Object)

containsValue

public boolean containsValue(Object ov)

Specified by:

containsValue in interface Map<Long,Float>

putAll

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

Specified by:

putAll in interface Map<Long,Float>

long2FloatEntrySet

public ObjectSet<Long2FloatMap.Entry> long2FloatEntrySet()

Description copied from interface: Long2FloatMap

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 Long2FloatMap.entrySet() so that it returns an ObjectSet of objects of type Long2FloatMap.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

long2FloatEntrySet in interface Long2FloatMap

Returns:

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

See Also:

Long2FloatMap.entrySet()

keySet

public LongSet keySet()

Description copied from interface: Long2FloatMap

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 Long2FloatMap

Specified by:

keySet in interface Map<Long,Float>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public FloatCollection values()

Description copied from interface: Long2FloatMap

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 Long2FloatMap

Specified by:

values in interface Map<Long,Float>

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<Long,Float>

entrySet

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

Description copied from interface: Long2FloatMap

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 Long2FloatMap

Specified by:

entrySet in interface Map<Long,Float>

Returns:

a set view of the mappings contained in this map.

Specified by:

hashCode in interface Map<Long,Float>

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Specified by:

equals in interface Map<Long,Float>

Overrides:

equals in class Object

toString

public String toString()

Overrides:
