Detailed Description

A 2D element of the topology.

Base class for a face (a triangle or a quadrilateral). 2D elements of the topology are defined by 1D elements, ie. a triangle is defined by three edges.

On this level a unique counter for all 2D connectors is implemented. In addition to the interface prescribed by connector methods to query the 0D and 1D components of this connector are declared.

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::Connector2::child ( uint  i ) const

pure virtual

Implements concepts::Connector.

Implemented in concepts::SphericalSurface, concepts::InfiniteQuad, concepts::Quad, and concepts::Triangle.

child() [2/2]

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

pure virtual

Returns the ith child of the connector.

Parameters

i	Index of the child
mode	If mode = false(0) the child is created if it does not yet exist, if mode = true(1) no new children are created (ie. 0 is returned if no children exist).

Invariant

Either all children or no children exist.

Implements concepts::Connector.

Implemented in concepts::InfiniteQuad, concepts::Quad, concepts::Triangle, and concepts::SphericalSurface.

edge()

virtual Connector1* concepts::Connector2::edge ( uint  i ) const

pure 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

Implemented in concepts::SphericalSurface, concepts::InfiniteQuad, concepts::Quad, and concepts::Triangle.

info()

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

protectedvirtualinherited

Returns information in an output stream.

Reimplemented from concepts::OutputOperator.

Reimplemented in concepts::Sphere, concepts::SphericalSurface, concepts::Hexahedron, concepts::Tetrahedron, concepts::InfiniteQuad, concepts::Quad, concepts::Triangle, concepts::InfiniteEdge, concepts::Edge, and concepts::Vertex.

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()

virtual Connector0* concepts::Connector2::vertex ( uint  i ) const

pure virtual

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

Implemented in concepts::SphericalSurface, concepts::InfiniteQuad, concepts::Quad, and concepts::Triangle.
