Detailed Description

Triangle of a mesh, defined by three vertices.

Definition at line 24 of file Triangle.hpp.

Member Typedef Documentation

◆ const_iterator

using precice::mesh::Triangle::const_iterator = IndexRangeIterator<const Triangle, const Vertex::RawCoords>

Type of the read-only const random-access iterator over Vertex coords.

This index-based iterator iterates over the vertices of this Triangle. The returned value is the forwarded result of Vertex::getCoords. It is thus a read-only random-access iterator.

Definition at line 32 of file Triangle.hpp.

◆ iterator

using precice::mesh::Triangle::iterator = const_iterator

Type of the read-only random access vertex iterator.

Definition at line 35 of file Triangle.hpp.

◆ value_type

using precice::mesh::Triangle::value_type = Vertex::RawCoords

Fix for the Boost.Test versions 1.65.1 - 1.67.

Definition at line 38 of file Triangle.hpp.

Constructor & Destructor Documentation

◆ Triangle() [1/2]

precice::mesh::Triangle::Triangle	(	Edge &	edgeOne,
		Edge &	edgeTwo,
		Edge &	edgeThree )

Constructor based on 3 edges.

Definition at line 23 of file Triangle.cpp.

Here is the call graph for this function:

◆ Triangle() [2/2]

precice::mesh::Triangle::Triangle	(	Vertex &	VertexOne,
		Vertex &	VertexTwo,
		Vertex &	VertexThree )

Constructor based on 3 vertices

The vertices will be sorted by Vertex::getID(). This allows to weakly order triangles.
