Method Detail

put

public int put(short key,
               int value)

Description copied from interface: Short2IntMap

Type Specific method to reduce boxing/unboxing of values

Parameters:

key - the key that should be inserted,

value - the value that should be inserted

Returns:

the last present value or default return value.

See Also:

Map.put(Object, Object)

putIfAbsent

public int putIfAbsent(short key,
                       int value)

Description copied from interface: Short2IntMap

Type Specific method to reduce boxing/unboxing of values

Parameters:

key - the key that should be inserted,

value - the value that should be inserted

Returns:

the last present value or default return value.

See Also:

Map.putIfAbsent(Object, Object)

addTo

public int addTo(short key,
                 int value)

Description copied from interface: Short2IntMap

A Helper method to add a primitives together. If key is not present then this functions as a put.

Parameters:

key - the key that should be inserted,

value - the value that should be inserted / added

Returns:

the last present value or default return value.

subFrom

public int subFrom(short key,
                   int value)

Description copied from interface: Short2IntMap

A Helper method to subtract from primitive from each other. If the key is not present it will just return the defaultValue How the implementation works is that it will subtract from the current value (if not present it will do nothing) and fence it to the Short2IntMap.getDefaultReturnValue() If the fence is reached the element will be automaticall removed

Parameters:

key - that should be subtract from

value - that should be subtract

Returns:

the last present or default return value

remove

public int remove(short key)

Description copied from interface: Short2IntMap

Type Specific remove function to reduce boxing/unboxing

Parameters:

key - the element that should be removed

Returns:

the value that was removed or default return value

removeOrDefault

public int removeOrDefault(short key,
                           int defaultValue)

Description copied from interface: Short2IntMap

Type-Specific Remove function with a default return value if wanted.

Parameters:

key - the element that should be removed

defaultValue - the value that should be returned if the entry doesn't exist

Returns:

the value that was removed or default value

See Also:

Map.remove(Object, Object)

remove

public boolean remove(short key,
                      int value)

Description copied from interface: Short2IntMap

Type Specific remove function to reduce boxing/unboxing

Parameters:

key - the element that should be removed

value - the expected value that should be found

Returns:

true if the key and value was found and removed

See Also:

Map.remove(Object, Object)

get

public int get(short key)

Description copied from interface: Short2IntMap

A Type Specific get method to reduce boxing/unboxing

Parameters:
