GetBufferSpecs()

HDST_API void GetBufferSpecs ( HdBufferSpecVector *  specs ) const

overridevirtual

Add the buffer spec for this computation into given bufferspec vector.

Caller has to allocate the destination buffer with respect to the BufferSpecs, and passes the range when registering the computation.

Implements HdStComputation.

GetNumOutputElements()

HDST_API int GetNumOutputElements ( ) const

overridevirtual

Returns the size of its destination buffer (located by range argument of Execute()).

This function will be called after all HdBufferSources have been resolved and commited, so it can use the result of those buffer source results. Returning 0 means it doesn't need to resize.

Implements HdStComputation.
