public static class Double2LongMaps.Singleton

extends AbstractDouble2LongMap

implements 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

containsKey

public boolean containsKey(double k)

Description copied from class: AbstractDouble2LongMap

Checks whether the given value is contained in AbstractDouble2LongMap.keySet().

Specified by:

containsKey in interface Double2LongMap

Overrides:

containsKey in class AbstractDouble2LongMap

containsValue

public boolean containsValue(long v)

Description copied from class: AbstractDouble2LongMap

Checks whether the given value is contained in AbstractDouble2LongMap.values().

Specified by:

containsValue in interface Double2LongMap

Overrides:

containsValue in class AbstractDouble2LongMap

putAll

public void putAll(Map m)

Description copied from class: AbstractDouble2LongMap

Puts all pairs in the given map. If the map implements the interface of this map, it uses the faster iterators.

Specified by:

putAll in interface Map

Overrides:

putAll in class AbstractDouble2LongMap

Parameters:

m - a map.

entrySet

public Set entrySet()

Specified by:

entrySet in interface Map

keySet

public Set keySet()

Description copied from class: AbstractDouble2LongMap

Returns a type-specific-set view of the keys of this map.

The view is backed by the set returned by Map.entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.

Specified by:

keySet in interface Map

Overrides:

keySet in class AbstractDouble2LongMap

Returns:

a set view of the keys of this map; it may be safely cast to a type-specific interface.

values

public Collection values()

Description copied from class: AbstractDouble2LongMap

Returns a type-specific-set view of the values of this map.

The view is backed by the set returned by Map.entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.

Specified by:

values in interface Map

Overrides:

values in class AbstractDouble2LongMap

Returns:

a set view of the values of this map; it may be safely cast to a type-specific interface.

get

public long get(double k)

Description copied from interface: Double2LongMap

Returns the value to which the given key is mapped.

Specified by:

get in interface Double2LongMap

Parameters:

k - the key.

Returns:

the corresponding value, or the default return value if no value was present for the given key.

Map.get(Object)

size

public int size()

Specified by:

size in interface Map

clone

public Object clone()
