const [virtual]

Virtual copy constructor.

Implements concepts::MappingEdge2d.

virtual Real concepts::MappingEdge2d::curvature	(	const Real	t,
		uint	n = 0
	)		const [virtual, inherited]

Returns the n-th derivative of the curvature.

It's implemented in general for n = 0,1 and works with curved edges. Can be overwritten in derived classes for performance reasons.

Reimplemented in concepts::InverseMappingEdge2d, concepts::MappingStraightEdge2d, concepts::CircleMappingEdge2d, and concepts::MappingParallelEdge2d.

virtual Real2d concepts::EllipseMappingEdge2d::derivative	(	const Real	t,
		const uint	n = 1
	)		const [virtual]

Returns the n-th derivative.

Implements concepts::MappingEdge2d.

virtual std::ostream& concepts::EllipseMappingEdge2d::info

(

std::ostream &

os

)

const [protected, virtual]

Returns information in an output stream.

Reimplemented from concepts::MappingEdge2d.

virtual EllipseMappingEdge2d* concepts::EllipseMappingEdge2d::inverse

const [virtual]

Returns the mapping of the edge in inverse direction.

Reimplemented from concepts::MappingEdge2d.

Implements concepts::MappingEdge2d.

EllipseMappingEdge2d* concepts::EllipseMappingEdge2d::part	(	const Real	t0,
		const Real	t1
	)		const [virtual]

Returns a new object of an element map for a rectangular part of the reference cell defined by the two points.
