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

◆ child() [2/2]

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

Returns the ith child of the connector.

Parameters
iIndex of the child
modeIf 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
iIndex 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

◆ 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
connOther 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
iIndex of the vertex

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