Method Detail

put

public double put(long key,
                  double value)

Description copied from interface: Long2DoubleMap

Type Specific method to reduce boxing/unboxing of values

Specified by:

put in interface Long2DoubleMap

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 double putIfAbsent(long key,
                          double value)

Description copied from interface: Long2DoubleMap

Type Specific method to reduce boxing/unboxing of values

Specified by:

putIfAbsent in interface Long2DoubleMap

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 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.

Specified by:

addTo in interface Long2DoubleMap

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 double subFrom(long key,
                      double value)

Description copied from interface: Long2DoubleMap

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 Long2DoubleMap.getDefaultReturnValue() If the fence is reached the element will be automaticall removed

Specified by:

key - that should be subtract from

Specified by:

removeOrDefault in interface Long2DoubleMap

Parameters:

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

Returns:

the value that was removed or default value
