	Transforms a vector \( \boldsymbol{x} \) from \( V\) to \( V'\). If postrestrict == true then \(\boldsymbol{R}^T_{\boldsymbol{\tilde U}', \boldsymbol{U}'} \boldsymbol{S}_{\boldsymbol{\tilde V}}\) is applied instead of the full transformation.

	Transforms a vector \( \boldsymbol{x} \) from \( V'\) to \( V\). If prerestrict == true then \(\boldsymbol{S}^T_{\boldsymbol{\tilde U}}\) is applied instead of the full transformation.

Detailed Description

template<typename B, typename CU = EmptyTransformation, typename CV = EmptyTransformation>
class Dune::PDELab::LocalAssemblerBase< B, CU, CV >

Base class for local assembler.

This class provides some generic behavior required for local assembler implementations. This includes the access of the global vectors and matrices via local indices and local function spaces with regard to the constraint mappings.

Template Parameters

B	The matrix backend
CU	Constraints maps for the individual dofs (trial space)
CV	Constraints maps for the individual dofs (test space)
