public static class Double2BooleanMaps.Singleton
extends Double2BooleanFunctions.Singleton
implements Double2BooleanMap, 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(boolean v)
Specified by:
containsValue in interface Double2BooleanMap
See Also:
Map.containsValue(Object)

containsValue

public boolean containsValue(Object ov)
Specified by:
containsValue in interface Map<Double,Boolean>

putAll

public void putAll(Map<? extends Double,? extends Boolean> m)
Specified by:
putAll in interface Map<Double,Boolean>

double2BooleanEntrySet

public ObjectSet<Double2BooleanMap.Entry> double2BooleanEntrySet()
Description copied from interface: Double2BooleanMap
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 Double2BooleanMap.entrySet() so that it returns an ObjectSet of objects of type Double2BooleanMap.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:
double2BooleanEntrySet in interface Double2BooleanMap
Returns:
a type-specific set view of the mappings contained in this map.
See Also:
Double2BooleanMap.entrySet()

keySet

public DoubleSet keySet()
Description copied from interface: Double2BooleanMap
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 Double2BooleanMap
Specified by:
keySet in interface Map<Double,Boolean>
Returns:
a set view of the keys contained in this map.
See Also:
Map.keySet()

values

public BooleanCollection values()
Description copied from interface: Double2BooleanMap
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 Double2BooleanMap
Specified by:
values in interface Map<Double,Boolean>
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<Double,Boolean>

entrySet

public ObjectSet<Map.Entry<Double,Boolean>> entrySet()
Description copied from interface: Double2BooleanMap
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 Double2BooleanMap
Specified by:
entrySet in interface Map<Double,Boolean>
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<Double,Boolean>
Overrides:
hashCode in class Object

equals

public boolean equals(Object o)
Specified by:
equals in interface Map<Double,Boolean>
Overrides:
equals in class Object

toString

public String toString()
Overrides:
toString in class Object
