Detailed Description

An edge in the topology. Implements the abstract methods from the parent classes to query the children and the vertices of the edge.

Examples

meshes.cc.

Definition at line 73 of file topology.hh.

Constructor & Destructor Documentation

Edge()

concepts::Edge::Edge	(	Vertex &	vtx0,
		Vertex &	vtx1,
		const Attribute	attrib = Attribute()
	)

Constructor.

Parameters

vtx0	Starting vertex of this edge
vtx1	Ending vertex of this 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 Edge * concepts::Edge::child ( uint  i ) const

virtual

Implements concepts::Connector1.

child() [2/2]

virtual Edge * concepts::Edge::child ( uint  i, bool  mode = 0  )

virtual

Returns a child.

When creating new children, the starting vertex of the first edge is the child of the starting vertex of this edge, the ending Vertex is new. It is also the starting vertex for the second child. The ending vertex of the second child is the child of the ending Vertex of this edge.

Parameters

i	Index of the child to be returned.
mode	mode = 1: No children are created mode = 0: If no child exists, two new children are created (with the same attributes as this one).

Implements concepts::Connector1.

clone()

Edge * concepts::Edge::clone ( Vertex &  vtx0, Vertex &  vtx1  ) const

inline

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

Definition at line 132 of file topology.hh.

info()

virtual std::ostream & concepts::Edge::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.

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

setAttrib()

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

inlineinherited

Definition at line 111 of file connector.hh.

vertex()

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

inlinevirtual

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

Parameters

i	Index of the vertex

Implements concepts::Connector1.

Definition at line 103 of file topology.hh.
