Detailed Description

template<class Mesh>
class OpenMesh::Iterators::ConstVertexOHalfedgeIterT< Mesh >

Circulator.

Member Function Documentation

template<class Mesh>
HalfedgeHandle OpenMesh::Iterators::ConstVertexOHalfedgeIterT< Mesh >::current_halfedge_handle ( ) const
inline

Get the current halfedge.

There are Vertex*Iters and Face*Iters. For both the current state is defined by the current halfedge. This is what this method returns.

template<class Mesh>
OpenMesh::Iterators::ConstVertexOHalfedgeIterT< Mesh >::operator bool ( ) const
inline

Returns whether the circulator is still valid.

After one complete round around a vertex/face the circulator becomes invalid, i.e. this function will return false. Nevertheless you can continue circulating. This method just tells you whether you have completed the first round.
