Detailed Description

template<typename BasisFunctionType_, typename KernelType_, typename ResultType_>
class Bempp::GeneralHypersingularIntegralOperator< BasisFunctionType_, KernelType_, ResultType_ >

Standard implementation of a hypersingular singular integral operator.

This class provides an implementation of the interface defined by HypersingularIntegralOperator that is sufficient for most purposes. The constructor takes eight functor objects representing the four elements of the operator's weak form (collection of kernels, collections of test and trial function transformations, and the weak form integrand) for its two representations: one valid for all pairs of test and trial functions, the other necessarily valid only for test and trial functions with nonoverlapping support, but with a more restricted form (see the documentation of HypersingularIntegralOperator for more details). These functors are used to construct instances of appropriate instantiations of DefaultCollectionOfKernels, DefaultCollectionOfShapesetTransformations and DefaultTestKernelTrialIntegral. These objects are stored as private member variables and are returned by the implementations of the virtual methods kernels(), testTransformations(), trialTransformations(), integral(), offDiagonalKernels(), offDiagonalTestTransformations(), offDiagonalTrialTransformations() and offDiagonalIntegral().

Template Parameters

BasisFunctionType_	Type of the values of the (components of the) basis functions into which functions acted upon by the operator are expanded.
KernelType_	Type of the values of the (components of the) kernel functions occurring in the integrand of the operator.
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.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

This constructor takes the same arguments as the preceding one except for the integral and offDiagonalIntegral arguments, which should be shared pointers to instances of (a subclass of) Fiber::TestKernelTrialIntegral rather than functors.
