void mfem::DivDivIntegrator::AddMultPA	(	const Vector &	x,
		Vector &	y
	)		const

protectedvirtual

Method for partially assembled action.

Perform the action of integrator on the input x and add the result to the output y. Both x and y are E-vectors, i.e. they represent the element-wise discontinuous version of the FE space.

This method can be called only after the method AssemblePA() has been called.

Reimplemented from mfem::BilinearFormIntegrator.
