IMPORT_C void	SetMappingTableValues	(	TReal32	aStart,
			TReal32	aEnd,
			MAlfTableMappingFunctionDataProvider *	aFunction
		)

Calculates mapping table for given range using given mapping data provider function. This fucntion should be called at least once to initialize the mapping table values.

Parameters

TReal32 aStart	Start value for the mapping table
TReal32 aEnd	End value for the mapping table
MAlfTableMappingFunctionDataProvider * aFunction	Function that is used to calculate mapping table values.
