Parameters:

key - the element that should be removed

Returns:

the value that was removed or default return value

remCharOrDefault

public double remCharOrDefault(char key,
                               double defaultValue)

Description copied from interface: Char2DoubleMap

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(char key,
                      double value)

Description copied from interface: Char2DoubleMap

Type Specific remove function to reduce boxing/unboxing

Parameters:

key - the element that should be removed

value - the expected value that should be found
