                  double value)

Description copied from interface: Float2DoubleMap

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.

putIfAbsent

public double putIfAbsent(float key,
                          double value)

Description copied from interface: Float2DoubleMap

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:

addTo

public double addTo(float key,
                    double value)

Description copied from interface: Float2DoubleMap

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.

remFloat

public double remFloat(float key)

Description copied from interface: Float2DoubleMap

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

remFloatOrDefault

public double remFloatOrDefault(float key,
                                double defaultValue)

Description copied from interface: Float2DoubleMap

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(float key,
                      double value)

Description copied from interface: Float2DoubleMap

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)

public double getDouble(float key)

Description copied from interface: Float2DoubleMap

A Type Specific get method to reduce boxing/unboxing

Parameters:
