Detailed Description

A triangle in the topology.

Implements the abstract methods from the parent classes to query the children, the vertices and the edges of the triangle.

Every edge can have two different orientations in the triangle, this orientation is stored in the array rho.

Examples: meshes.cc.

Constructor & Destructor Documentation

◆ Triangle() [1/2]

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

Constructor.

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

Parameters

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

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 Triangle* concepts::Triangle::child ( uint i ) const

virtual

Implements concepts::Connector2.

◆ child() [2/2]

virtual Triangle* concepts::Triangle::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). The triangle is cut into four new triangles by joining the midpoints of its edges.

Parameters

i	Index of the child to be returned.
mode	mode = 1: No children are created mode = 0: If no children exist, four new children are created.

Implements concepts::Connector2.

◆ clone()

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

inline

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

Definition at line 258 of file topology.hh.

◆ edge()

Edge* concepts::Triangle::edge ( uint i ) const

inlinevirtual

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.

Definition at line 224 of file topology.hh.

◆ info()

virtual std::ostream& concepts::Triangle::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

◆ rho()

Z2 concepts::Triangle::rho ( int i ) const

inline

Returns the orientation of an edge.

Parameters

i	Index of the edge.

Definition at line 230 of file topology.hh.

◆ setAttrib()

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

inlineinherited

Definition at line 111 of file connector.hh.

◆ vertex()

Vertex* concepts::Triangle::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.
