Method Detail

put

public long put(int key,
                long value)

Description copied from interface: Int2LongMap

Type Specific method to reduce boxing/unboxing of values

Specified by:

put in interface Int2LongMap

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 long putIfAbsent(int key,
                        long value)

Description copied from interface: Int2LongMap

Type Specific method to reduce boxing/unboxing of values

Specified by:

putIfAbsent in interface Int2LongMap

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:

addTo

public long addTo(int key,
                  long value)

Description copied from interface: Int2LongMap

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

Specified by:

addTo in interface Int2LongMap

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 long subFrom(int key,
                    long value)

Description copied from interface: Int2LongMap

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 Int2LongMap.getDefaultReturnValue() If the fence is reached the element will be automaticall removed

Specified by:

Parameters:

key - that should be subtract from

value - that should be subtract

Returns:

the last present or default return value

Specified by:

removeOrDefault in interface Int2LongMap

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
