bool AssociateHungryDiffOpWithOperand::doTransform ( const RCP< ScalarExpr > &  left,
const RCP< ScalarExpr > &  right,
RCP< ScalarExpr > &  rtn 
) const [virtual]

Test whether the transform is applicable in this case, and if it is, apply it.

The return value is true is the transformation was applied, otherwise false. Returns by non-const reference the transformed expression.
