Member Function Documentation

CurveCount()

virtual int CRhRdkCurveGraphEvaluator::CurveCount ( void  ) const

virtual

Returns

The number of curves available to the evaluator.

EVF()

virtual void* CRhRdkCurveGraphEvaluator::EVF ( const wchar_t *  wszFunc, void *  pvData  )

virtual

Emergency virtual function for future expansion.

GetCurveY()

virtual double CRhRdkCurveGraphEvaluator::GetCurveY ( int  iCurveIndex, double  dX  ) const

virtual

Calculates the Y coordinate of a curve at the given X coordinate.

Parameters

iCurveIndex	is the curve index of one of the curves on the graph.
dX	is the X value to get the Y value for.

Returns

The Y coordinate at the given X coordinate or ON_UNSET_VALUE if the curve index is invalid.
