Detailed Description

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

Standard implementation of an elementary local operator.

This class provides an implementation of the interface defined by ElementaryLocalOperator that is sufficient for most purposes. The constructor takes three functor objects representing the three elements of the operator's weak form: collections of test and trial basis function transformations and the weak form integrand. These functors are used to construct instances of appropriate instantiations of DefaultCollectionOfShapesetTransformations and DefaultTestKernelTrialIntegral. These objects are stored as private member variables and are returned by the implementations of the virtual methods testTransformations(), trialTransformations() and integral().

Template Parameters

BasisFunctionType_	Type of the values of the (components of the) basis functions into which functions acted upon by the operator are expanded.
ResultType_	Type used to represent elements of the weak form of the operator.

All three template parameters can take the following values: float, double, std::complex<float> and std::complex<double>. All types must have the same precision: for instance, mixing float with std::complex<double> is not allowed. If either BasisFunctionType_ or KernelType_ is a complex type, then ResultType_ must be set to the same type.

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.
[in]	testTransformationsFunctor	A functor object to be used to evaluate the collection of test function transformations at a single point. The TestTransformationsFunctor class must provide the interface defined in the documentation of DefaultCollectionOfShapesetTransformations.
[in]	trialTransformationsFunctor	A functor object to be used to evaluate the collection of trial function transformations at a single point. The TrialTransformationsFunctor class must provide the interface defined in the documentation of DefaultCollectionOfShapesetTransformations.
[in]	integrandFunctor	A functor object to be used to evaluate the integrand of the weak form at a single point. The IntegrandFunctor class must provide the interface defined in the documentation of DefaultTestTrialIntegral.

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

The implementation of this constructor is contained in general_elementary_local_operator_imp.hpp. This header must be included in any file creating a new GeneralElementaryLocalOperator object.

template<typename BasisFunctionType_ , typename ResultType_ >

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

inlinevirtual

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.
