Public Member Functions inherited from GClasses::GIncrementalTransform
	GIncrementalTransform ()

	GIncrementalTransform (const GDomNode *pNode)

virtual	~GIncrementalTransform ()

const GRelation &	after () const
	Returns a relation object describing the data after it is transformed. More...

const GRelation &	before () const
	Returns a relation object describing the data before it is transformed. More...

GVec &	innerBuf ()
	Returns a buffer of sufficient size to store an inner (transformed) vector. The caller should not to delete the buffer. The same buffer will be returned each time. More...

virtual GMatrix *	reduce (const GMatrix &in)
	This calls train, then calls transformBatch, and returns the result. More...

void	setAfter (GRelation *pRel)
	Sets the after relation. Takes ownership of pRel. More...

void	setBefore (GRelation *pRel)
	Sets the before relation. Takes ownership of pRel. More...

void	train (const GMatrix &data)
	Trains the transform on the data in pData. (This method may be a no-op for transformations that always behave in the same manner.) More...

void	train (const GRelation &pRelation)
	"Trains" the transform without any data. More...

virtual GMatrix *	transformBatch (const GMatrix &in)
	This assumes that train has already been called, and transforms all the rows in in returning the resulting matrix. The caller is responsible for deleting the new matrix. More...

virtual std::unique_ptr< GMatrix >	untransformBatch (const GMatrix &in)
	This assumes train was previously called, and untransforms all the rows in pIn and returns the results. More...
