Detailed Description

template<class DomainFunction, class RangeFunction = DomainFunction>
class Dune::Fem::Operator< DomainFunction, RangeFunction >

abstract operator

Operators map a discrete function onto another discrete function. Their interface is described by the abstract class Operator.

Template Parameters

DomainFunction	type of discrete function for the domain
RangeFunction	type of discrete function for the range (defaults to DomainFunction)

An interface class:

Member Function Documentation

finalize()

template<class DomainFunction , class RangeFunction = DomainFunction>

virtual void Dune::Fem::Operator< DomainFunction, RangeFunction >::finalize ( )

inlinevirtual

finalization of operator

Note

The default implementation is empty.

Reimplemented in Dune::Fem::SparseRowLinearOperator< DomainFunction, RangeFunction, Matrix >.

Referenced by Dune::Fem::Solver::CGInverseOperator< DiscreteFunction >::operator()().

nonlinear()

template<class DomainFunction , class RangeFunction = DomainFunction>

virtual bool Dune::Fem::Operator< DomainFunction, RangeFunction >::nonlinear ( ) const

inlinevirtual

Return true if the Operator is nonlinear and false otherwise (default is true).

Reimplemented in Dune::Fem::LinearOperator< DomainFunction, RangeFunction >, Dune::Fem::LinearOperator< DomainFunction, DomainFunction >, Dune::Fem::LinearOperator< AdaptiveDiscreteFunction< DiscreteFunctionSpace >, AdaptiveDiscreteFunction< DiscreteFunctionSpace > >, and Dune::Fem::LinearOperator< DomainFunction, RangeFunction >.

operator()()

template<class DomainFunction , class RangeFunction = DomainFunction>

virtual void Dune::Fem::Operator< DomainFunction, RangeFunction >::operator() ( const DomainFunctionType &  u, RangeFunctionType &  w  ) const

pure virtual

application operator

Parameters

[in]	u	argument discrete function
[out]	w	destination discrete function

Note

This method has to be implemented by all derived classes.
