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.

None of the shared pointers may be null and the spaces range and dualToRange must be defined on the same grid, otherwise an exception is thrown.

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_ >.

virtual const TestTrialIntegral& Bempp::ElementaryLocalOperator< BasisFunctionType_, ResultType_ >::integral ( ) const

privatepure virtual

Return an object representing the integral that is the weak form of this operator.

Subclasses of TestTrialIntegral implement functions that evaluate the integral using the data provided by a pair of CollectionOfShapesetTransformations objects representing the test and trial function transformations occurring in the integrand.

Implemented in Bempp::IdentityOperator< BasisFunctionType_, ResultType_ >, Bempp::GeneralElementaryLocalOperator< BasisFunctionType_, ResultType_ >, and Bempp::Maxwell3dIdentityOperator< BasisFunctionType_, ResultType_ >.
