Detailed Description

template<class EdgeType, class ParentType>
class libMesh::SideEdge< EdgeType, ParentType >

This defines the SideEdge class.

Like Side, SideEdge is basically a proxy (or stand-in replacement) class, this time for an element's edge. It acts like a standard Elem, but allocates no additional memory for storing connectivity. Instead, its nodes are mapped directly from the parent element (the element for which the side is created). Similarly, you cannot access the neighbors of a side since it does not store any.
