Detailed Description

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

Circulator.

Member Function Documentation

template<class Mesh>

HalfedgeHandle OpenMesh::Iterators::VertexEdgeIterT< 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::VertexEdgeIterT< 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.
