Detailed Description

This class grants special access to the raw VdfVector data associated with inputs and outputs on a VdfNode.

Note, that input and output data is typically accessed using the VdfContext. In some special cases, nodes may require type-agnostic access to the entire VdfVector stored for a specific input or output.

We do not want this class to be used in typical plugin code (mover, gprims, etc.), thus inputs and outputs are referred to using VdfInput and VdfOutput instances, rather than name tokens. Only classes derived from VdfNode will typically have access to these objects.

Member Function Documentation

VDF_API const VdfVector* VdfRawValueAccessor::GetInputVector	(	const VdfInput &	input,
		VdfMask *	mask = nullptr
	)		const

Returns the first VdfVector at the input for input. Returns nullptr if there is no connection on the supplied input or if the requested input does not exist.

Note, this method purposefully accepts a VdfInput instead of a TfToken, such that it can only be used where VdfInputs are available.

VDF_API void VdfRawValueAccessor::SetOutputVector	(	const VdfOutput &	output,
		const VdfMask &	mask,
		const VdfVector &	value
	)

Sets the output value to the given value using the passed in mask.

Note, this method purposefully accepts a VdfOutput instead of a TfToken, such that it can only be used where VdfOutputs are available.

VDF_API void VdfRawValueAccessor::SetOutputVector	(	const VdfOutput &	output,
		const VdfMask &	mask,
		VdfVector &&	value
	)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
