Detailed Description

template<bool Const = false>
class OpenABF::HalfEdgeMesh< T, Dim, VertexTraits, EdgeTraits, FaceTraits >::EdgesIterator< Const >

Iterator that lazily flattens all face edges across all faces.

Provides a single flat sequence over all face (non-boundary) edges in the mesh without allocating a vector. Internally advances through faces_ and uses FaceIterator within each face.

Template Parameters

Const

If true, is a const iterator
