#include <dune/pdelab/gridoperator/onestep/localassembler.hh>

Public Types
typedef LA0	LocalAssemblerDT0
	The types of the local assemblers of order one and zero.

typedef Dune::PDELab::LocalAssemblerBase< typename GO::Traits::MatrixBackend, typename GO::Traits::TrialGridFunctionSpaceConstraints, typename GO::Traits::TestGridFunctionSpaceConstraints >	Base
	The base class.

typedef Traits::RangeField	Real
	The local operators type for real numbers e.g. time.

typedef Dune::PDELab::TimeSteppingParameterInterface< Real >	OneStepParameters
	The type of the one step parameter object.

Public Member Functions
	OneStepLocalAssembler (LA0 &la0_, LA1 &la1_, typename Traits::Residual &const_residual_)
	Constructor with empty constraints.

void	preStep (Real time_, Real dt_, int stages_)

void	setMethod (const OneStepParameters &method_)
	Set the one step method parameters.

void	setStage (int stage_)
	Set the current stage of the one step scheme.

void	setDTAssemblingMode (DTAssemblingMode dt_mode_)

Real	timeAtStage (int stage_) const
	Access time at given stage.

Real	timeAtStage () const
	Access time at given stage.

const GO::Traits::TrialGridFunctionSpaceConstraints &	trialConstraints () const
	get the constraints on the trial grid function space

const GO::Traits::TestGridFunctionSpaceConstraints &	testConstraints () const
	get the constraints on the test grid function space

std::enable_if< AlwaysTrue< X >::value &&!std::is_same< GO::Traits::TestGridFunctionSpaceConstraints, EmptyTransformation >::value >::type	forwardtransform (X &x, const bool postrestrict=false) const
	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.

std::enable_if< AlwaysTrue< X >::value &&!std::is_same< GO::Traits::TestGridFunctionSpaceConstraints, EmptyTransformation >::value >::type	backtransform (X &x, const bool prerestrict=false) const
	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.
