Field Detail

EMPTY_FUNCTION

public static final Char2ObjectFunctions.EmptyFunction EMPTY_FUNCTION

An empty type-specific function (immutable). It is serializable and cloneable.

Method Detail

singleton

public static <V> Char2ObjectFunction<V> singleton(char key,
                                                   V value)

Returns a type-specific immutable function containing only the specified pair. The returned function is serializable and cloneable.

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

Parameters:

key - the only key of the returned function.

value - the only value of the returned function.

Returns:

a type-specific immutable function containing just the pair <key,value>.

singleton

public static <V> Char2ObjectFunction<V> singleton(Character key,
                                                   V value)

Returns a type-specific immutable function containing only the specified pair. The returned function is serializable and cloneable.

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

Parameters:

key - the only key of the returned function.

value - the only value of the returned function.

Returns:

a type-specific immutable function containing just the pair <key,value>.

synchronize

public static <V> Char2ObjectFunction<V> synchronize(Char2ObjectFunction<V> f)

Returns a synchronized type-specific function backed by the given type-specific function.

Parameters:

f - the function to be wrapped in a synchronized function.

Returns:

a synchronized view of the specified function.

Collections.synchronizedMap(java.util.Map)

synchronize

public static <V> Char2ObjectFunction<V> synchronize(Char2ObjectFunction<V> f,
                                                     Object sync)

Returns a synchronized type-specific function backed by the given type-specific function, using an assigned object to synchronize.

Parameters:

f - the function to be wrapped in a synchronized function.

sync - an object that will be used to synchronize the access to the function.

Returns:

a synchronized view of the specified function.

See Also:

Collections.synchronizedMap(java.util.Map)

unmodifiable

public static <V> Char2ObjectFunction<V> unmodifiable(Char2ObjectFunction<V> f)

Returns an unmodifiable type-specific function backed by the given type-specific function.

Parameters:

f - the function to be wrapped in an unmodifiable function.

Returns:

an unmodifiable view of the specified function.
