addTo

public double addTo(long key,
                    double value)

Description copied from interface: Long2DoubleMap

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.

remLong

public double remLong(long key)

Description copied from interface: Long2DoubleMap

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

remLongOrDefault

public double remLongOrDefault(long key,
                               double defaultValue)

Description copied from interface: Long2DoubleMap

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(long key,
                      double value)

Description copied from interface: Long2DoubleMap

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)
