Detailed Description

template<typename BasisFunctionType_, typename ResultType_>
class Bempp::NullOperator< BasisFunctionType_, ResultType_ >

Null operator.

This class represents an operator that always produces a zero function.

See AbstractBoundaryOperator for the documentation of the template parameters.

Use nullOperator() to create a BoundaryOperator object wrapping a null operator.

Constructor & Destructor Documentation

template<typename BasisFunctionType , typename ResultType >

Bempp::NullOperator< BasisFunctionType, ResultType >::NullOperator	(	const shared_ptr< const Space< BasisFunctionType > > &	domain,
		const shared_ptr< const Space< BasisFunctionType > > &	range,
		const shared_ptr< const Space< BasisFunctionType > > &	dualToRange,
		const std::string &	label = `""`,
		int	symmetry = `AUTO_SYMMETRY`
	)

Constructor.

Parameters

[in]	domain	Function space being the domain of the operator.
[in]	range	Function space being the range of the operator.
[in]	dualToRange	Function space dual to the the range of the operator.
[in]	label	Textual label of the operator. If empty, a unique label is generated automatically.
[in]	symmetry	Symmetry of the weak form of the operator. Can be any combination of the flags defined in the enumeration type Symmetry. If set to AUTO_SYMMETRY (default), the symmetry is determined automatically by checking whether its domain and space dual to its range are equal. If so, the operator is marked as symmetric and Hermitian.

Member Function Documentation

template<typename BasisFunctionType , typename ResultType >

shared_ptr< DiscreteBoundaryOperator< ResultType > > Bempp::NullOperator< BasisFunctionType, ResultType >::assembleWeakFormImpl ( const Context< BasisFunctionType, ResultType > & context ) const

protectedvirtual

Assemble and return the operator's weak form.

This virtual function is invoked by assembleWeakForm() to do the actual work.

Implements Bempp::AbstractBoundaryOperator< BasisFunctionType_, ResultType_ >.

template<typename BasisFunctionType , typename ResultType >

shared_ptr< const AbstractBoundaryOperatorId > Bempp::NullOperator< BasisFunctionType, ResultType >::id ( ) const

virtual

Return the identifier of this operator.

Null operators are treated as equivalent if they have the same domain, range and dual to range.

Deprecated:: This function is deprecated and will be removed in a future version of BEM++.

Reimplemented from Bempp::AbstractBoundaryOperator< BasisFunctionType_, ResultType_ >.

		const shared_ptr< const Space< BasisFunctionType > > &	dualToRange,
		const std::string &	label = `""`,
		int	symmetry = `AUTO_SYMMETRY`
	)

This convenience function constructs an abstract null operator and wraps it in a BoundaryOperator object.

Parameters

[in]	context	A Context object that will be used to build the weak form of the identity operator when necessary.
[in]	domain	Function space being the domain of the identity operator.
[in]	range	Function space being the range of the identity operator.
[in]	dualToRange	Function space dual to the the range of the identity operator.
[in]	label	Textual label of the operator (optional, used for debugging).
[in]	symmetry	Symmetry of the weak form of the operator. Can be any combination of the flags defined in the enumeration type Symmetry. If set to AUTO_SYMMETRY (default), the symmetry is determined automatically by checking whether its domain and space dual to its range are equal. If so, the operator is marked as symetric and Hermitian.
