Detailed Description

A infinite quadrilateral in the topology, which possess one Edge and two InfiniteEdges since one edge lies in the infinite. Implements the abstract methods from the parent classes to query the children, the vertices and the edges of the quadrilateral.

The finite edge can have two different orientations in the quadrilateral, this orientation is stored in rho.

The edges are : 0 - first infinite edge 1 - finite edge 2 - second infinite edge The vertices are : 0 - vertex of first infinite edge 1 - vertex of second infinite edge if rho == 0 0 - first vertex of finite edge 1 - second vertex of finite edge if rho == 1 vice versa

Constructor & Destructor Documentation

◆ InfiniteQuad()

concepts::InfiniteQuad::InfiniteQuad	(	InfiniteEdge &	edg0,
		Edge &	edg1,
		InfiniteEdge &	edg2,
		const Attribute	attrib = `Attribute()`
	)

Constructor. Creates a quadrilateral out of three edges. The edges must form an infinite quadrilateral: the 1st and the 2nd edge, the 2nd and the 3rd edge must have a common vertex. The Edge can have an arbitrary orientation, which is detected and stored in rho_.

Parameters

edg0	1st edge.
edg1	2nd edge.
edg2	3rd edge.
attrib	Attribute of the edge

Member Function Documentation

◆ attrib()

const Attribute & concepts::Connector::attrib ( ) const

inlineinherited

Returns the attribute of the connector.

Definition at line 108 of file connector.hh.

◆ child() [1/2]

virtual const Connector2 * concepts::InfiniteQuad::child ( uint i ) const

virtual

Implements concepts::Connector2.

◆ child() [2/2]

virtual Connector2 * concepts::InfiniteQuad::child	(	uint	i,
		bool	mode = `0`
	)

virtual

Returns a child.

If children are created, four new children are created (with the same attributes as this one). All edges of the quadrilateral are refined and four new edges introduced.

Parameters

i	Index of the child to be returned.
mode	mode = 1: No children are created mode = 0: If no childs exist, four new children are created. setStrategy() is called before creating the children.

Implements concepts::Connector2.

◆ children_()

Scan< Connector2 > * concepts::InfiniteQuad::children_ ( ) const

inlineprotected

Scanner over the children.

Definition at line 522 of file topology.hh.

◆ clone()

InfiniteQuad * concepts::InfiniteQuad::clone	(	InfiniteEdge &	edg0,
		Edge &	edg1,
		InfiniteEdge &	edg2
	)		const

inline

Returns the pointer of a new Quad with the same attribute, the same key and the same rho but NO children and sibling

Definition at line 530 of file topology.hh.

◆ edge()

Connector1 * concepts::InfiniteQuad::edge ( uint i ) const

virtual

Returns a 1D component: edge. A 2D element consists of 1D and 0D elements, the edges can be queried here.

Parameters

i	Index of the edge

Implements concepts::Connector2.

◆ getStrategy()

const InfQuadSubdivision * concepts::InfiniteQuad::getStrategy ( ) const

inline

Returns the subdivision strategy of this quad.

If you want to find check against another strategy use

quad.getStrategy() == QuadSubdiv2V::instance()

Definition at line 498 of file topology.hh.

◆ info()

virtual std::ostream & concepts::InfiniteQuad::info ( std::ostream & os ) const

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::Connector.

◆ key()

const Key & concepts::Connector::key ( ) const

inlineinherited

Returns the key of the connector.

Definition at line 105 of file connector.hh.

◆ numEdges()

int concepts::InfiniteQuad::numEdges ( ) const

inline

Definition at line 463 of file topology.hh.

◆ numVertices()

int concepts::InfiniteQuad::numVertices ( ) const

inline

Definition at line 459 of file topology.hh.

◆ operator==()

int concepts::Connector::operator== ( const Connector & cntr ) const

inlineinherited

Comparison operator.

Definition at line 102 of file connector.hh.

◆ related()

int concepts::Connector::related ( const Connector & conn ) const

inherited

Checks if this connector is related to conn. It is being checked if one of the two is an ancestor of the other.

Parameters

conn	Other connector

Returns: An integer i.
i=0 if there is no relationship or the connectors are identical
i>0 if conn is an ancestor of this connector
i<0 if conn is a descendant of this connector
|i| gives the number of generations between the connectors

◆ rho()

Z2 concepts::InfiniteQuad::rho ( ) const

inline

Returns the orientation of the finite edge.

rho = 0 : Edge is oriented counter-clockwise in the quadrilateral. rho = 1 : Edge is oriented clockwise in the quadrilateral.

Definition at line 472 of file topology.hh.

◆ setAttrib()

void concepts::Connector::setAttrib ( uint attrb )

inlineinherited

Definition at line 111 of file connector.hh.

◆ setStrategy()

void concepts::InfiniteQuad::setStrategy ( const InfQuadSubdivision * strategy = 0 )

Sets the subdivision strategy of this quad.

If the parameter is set to 0 (or if the method is called without parameter) the strategy is set to the default (if not already set). The default subdivision strategy is subdivision into 4 children.

  @param strategy Pointer to an instance of a subdivision strategy.

Exceptions

StrategyChange if the change is not allowed (the change is not allowed if there are children present)

◆ vertex()

Vertex * concepts::InfiniteQuad::vertex ( uint i ) const

inlinevirtual

Returns a 0D component: vertex A 2D element consists of 1D and 0D elements, the vertices can be queried here.

Parameters

i	Index of the vertex

Implements concepts::Connector2.
