Constructor & Destructor Documentation

◆ Identity()

template<class F = Real>
hp1D::Identity< F >::Identity ( const concepts::ElementFormulaContainer< F >  frm = concepts::ElementFormulaContainer< F >())

Constructor.

Member Function Documentation

◆ clone() [1/2]

template<class F = Real>
virtual Identity<F>* hp1D::Identity< F >::clone ( ) const
virtual

Virtual constructor.

Returns a pointer to a copy of itself. The caller is responsible to destroy this copy.

Implements concepts::Cloneable.

◆ clone() [2/2]

virtual BilinearForm* concepts::BilinearForm< Real , Real >::clone ( ) const
pure virtualinherited

Virtual constructor.

Returns a pointer to a copy of itself. The caller is responsible to destroy this copy.

◆ info()

template<class F = Real>
virtual std::ostream& hp1D::Identity< F >::info ( std::ostream &  os) const
protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::BilinearForm< Real, Real >.

◆ operator()() [1/3]

template<class F = Real>
void hp1D::Identity< F >::operator() ( const concepts::Element< Real > &  elmX,
const concepts::Element< Real > &  elmY,
concepts::ElementMatrix< F > &  em 
) const

◆ operator()() [2/3]

virtual void concepts::BilinearForm< Real , Real >::operator() ( const Element< G > &  elmX,
const Element< G > &  elmY,
ElementMatrix< F > &  em 
) const
pure virtualinherited

Evaluates the bilinear form for all shape functions on elmX and elmY and stores the result in the matrix em.

Postcondition
The returned matrix em has the correct size.
Parameters
elmXLeft element (test functions)
elmYRight element (trial functions)
emReturn element matrix

◆ operator()() [3/3]

virtual void concepts::BilinearForm< Real , Real >::operator() ( const Element< G > &  elmX,
const Element< G > &  elmY,
ElementMatrix< F > &  em,
const ElementPair< G > &  ep 
) const
inlinevirtualinherited

Evaluates the bilinear form for all shape functions on elmX and elmY and stores the result in the matrix em.

If this method is not reimplemented in a derived class, the default behaviour is to call the application operator without ep.

Postcondition
The returned matrix em has the correct size.
Parameters
elmXLeft element
elmYRight element
emReturn element matrix
epElement pair holding more information on the pair elmX and elmY
