| class MHuiMappingFunction |
Mapping function interface. Timed values use this interface for mapping the return value of a timed value evaluation. Can be used to define custom interpolation functions for example timed values.

Perform the mapping. Defines a function y = f(x, mode).
Implement this method that calculates a output value for a timed value based on the input value and a component/mode parameter.
For example the aValue input could be an angle, and the aMode could be a X or Y component enumeration, then the MapValue could calculate return a x or y position on a curve path.
| IMPORT_C TBool | MappingFunctionChanged | ( | ) | const [virtual] |
Determines whether the mapping function has changed since the last call to MHuiMappingFunction::MappingFunctionClearChanged().
By default, mapping functions themselves are assumed to be constant (not changing over time).
| IMPORT_C void | MappingFunctionClearChanged | ( | ) | [virtual] |
Clears the change flags of the mapping function. This is called by the refresh loop after a frame has been fully drawn.
