unsigned int libMesh::MeshTools::Generation::Private::idx ( const ElemType  type, const unsigned int  nx, const unsigned int  i, const unsigned int  j  )

inline

A useful inline function which replaces the macros used previously.

Not private since this is a namespace, but would be if this were a class. The first one returns the proper node number for 2D elements while the second one returns the node number for 3D elements.
