Field Detail

EMPTY_MAP

public static final Byte2FloatMaps.EmptyMap EMPTY_MAP
An empty type-specific map (immutable). It is serializable and cloneable.

Method Detail

singleton

public static Byte2FloatMap singleton(byte key,
                                      float value)
Returns a type-specific immutable map containing only the specified pair. The returned map is serializable and cloneable.

Note that albeit the returned map is immutable, its default return value may be changed.

Parameters:
key - the only key of the returned map.
value - the only value of the returned map.
Returns:
a type-specific immutable map containing just the pair <key,value>.

singleton

public static Byte2FloatMap singleton(java.lang.Byte key,
                                      java.lang.Float value)
Returns a type-specific immutable map containing only the specified pair. The returned map is serializable and cloneable.

Note that albeit the returned map is immutable, its default return value may be changed.

Parameters:
key - the only key of the returned map.
value - the only value of the returned map.
Returns:
a type-specific immutable map containing just the pair <key,value>.

synchronize

public static Byte2FloatMap synchronize(Byte2FloatMap m)
Returns a synchronized type-specific map backed by the given type-specific map.

Parameters:
m - the map to be wrapped in a synchronized map.
Returns:
a synchronized view of the specified map.

Collections.synchronizedMap(Map)

synchronize

public static Byte2FloatMap synchronize(Byte2FloatMap m,
                                        java.lang.Object sync)
Returns a synchronized type-specific map backed by the given type-specific map, using an assigned object to synchronize.

Parameters:
m - the map to be wrapped in a synchronized map.
sync - an object that will be used to synchronize the access to the map.
Returns:
a synchronized view of the specified map.
See Also:
Collections.synchronizedMap(Map)

unmodifiable

public static Byte2FloatMap unmodifiable(Byte2FloatMap m)
Returns an unmodifiable type-specific map backed by the given type-specific map.

Parameters:
m - the map to be wrapped in an unmodifiable map.
Returns:
an unmodifiable view of the specified map.
