Member Function Documentation

virtual const VtValue& GetInputValue ( const TfToken & name ) const

pure virtual

Obtains the value of an named input to the computation.

The code will issue a coding error and return a empty array if the input is missing or of a different type.

virtual const VtValue* GetOptionalInputValuePtr ( const TfToken & name ) const

pure virtual

Obtains the value of an named input to the computation.

If the input isn't present or of a different type nullptr will be returned.

virtual void RaiseComputationError ( )

pure virtual

Called to indicate an error occurred while executing a computation so that its output are invalid.

virtual void SetOutputValue	(	const TfToken &	name,
		const VtValue &	output
	)

pure virtual

Set the value of the specified output.
