gsHDomainIterator< T, d > Class Template Reference

Detailed Description

template<typename T, unsigned d>
class gismo::gsHDomainIterator< T, d >

Re-implements gsDomainIterator for iteration over all boundary elements of a hierarchical parameter domain.

See gsDomainIterator for more detailed documentation and an example of the typical use!!!
Used, e.g., for basis of classes gsHTensorBasis or gsTHBSplineBasis.

Member Function Documentation

virtual void adjacent ( const gsVector< bool > &  , gsDomainIterator< T > &    )

inlinevirtualinherited

Updates other with and adjacent element

Todo:

upgrade to return adjacent range instead

const gsVector<T>& centerPoint ( ) const

inlineinherited

Returns the center of the current element.

The current element is a d-dimensional hypercube. The coordinates of its upper corner is returned as a gsVector of length d.

E.g., if the current two-dimensional element is defined by [a,b]x[c,d], then [b,d] is returned (see also lowerCorner()).

virtual const T getPerpendicularCellSize ( ) const

inlinevirtualinherited

Returns the perpendicular cell size of boundary iterator.

Only works for boundary iterators. Returns the length from the boundary side to the parallel side not on the boundary.

Reimplemented in gsTensorDomainBoundaryIterator< T, D, uiter >.

const gsVector<T>& lowerCorner ( ) const

inlinevirtual

Returns the lower corner of the current element.

The current element is a d-dimensional hypercube. The coordinates of its lower corner is returned as a gsVector of length d.

E.g., if the current two-dimensional element is defined by [a,b]x[c,d], then [a,c] is returned (see also upperCorner()).

Reimplemented from gsDomainIterator< T >.

bool next ( )

inlinevirtual

Proceeds to the next element.

The function returns true if there are still elements remaining that have not been treated.
For the typical usage of this function, see the example in the documentation of gsDomainIterator.

Implements gsDomainIterator< T >.

void reset ( )

inlinevirtual

Resets the iterator so that it can be used for another iteration through all boundary elements.

Reimplemented from gsDomainIterator< T >.

void updateElement ( )

inlineprivate

Computes lower, upper and center point of the current element, maps the reference quadrature nodes and weights to the current element, and computes the active functions.

void updateLeaf ( )

inlineprivate

Computes lower, upper and center point of the current element, maps the reference quadrature nodes and weights to the current element, and computes the active functions.

const gsVector<T>& upperCorner ( ) const

inlinevirtual

Returns the upper corner of the current element.

The current element is a d-dimensional hypercube. The coordinates of its upper corner is returned as a gsVector of length d.

E.g., if the current two-dimensional element is defined by [a,b]x[c,d], then [b,d] is returned (see also lowerCorner()).

Reimplemented from gsDomainIterator< T >.

Member Data Documentation

bool m_isGood

protectedinherited

Flag indicating whether the domain iterator is "good". If it is "good", the iterator can continue to the next element.
