Member Function Documentation

◆ classID()

static const CClassID& IDOMSampledFunction::classID ( )

inlinestatic

Retrieves class id of IDOM.

Returns: CClassID class id of the element

◆ getBitsPerSample()

virtual uint8 IDOMSampledFunction::getBitsPerSample ( ) const

pure virtual

Get the bits per sample for the sample table.

Returns: bitsPerSample The bits per sample

◆ getInputEncode()

virtual void IDOMSampledFunction::getInputEncode	(	uint32	inputNum,
		float &	low,
		float &	high
	)		const

pure virtual

Get the input encode range for a given input to the function.

Parameters

inputNum	The 0-indexed input number
low	A reference to receive the low encode bound for the given inputNum
high	A reference to receive the high encode bound for the given inputNum

◆ getInterpolationMethod()

virtual eInterpolationMethod IDOMSampledFunction::getInterpolationMethod ( ) const

pure virtual

Get the interpolation method used for sample lookup.

Returns: eInterpolationMethod The interpolation method
