Detailed Description

template<typename Space_, int shape_dim_, typename DataType_>
class FEAT::Space::DofAssignmentBase< Space_, shape_dim_, DataType_ >

Mapping of mesh entities to FE basis functions associated with them.

In FEAT, every FE basis function is associated with mesh entities of exactly one shape dimension, i.e. vertices, facets or cells. The DofMapping maps a mesh cell (meaning only the highest-dimensional entities of a mesh) to a set of basis functions with nonempty support on that cell. It does, however, not contain any information about which entities of that cell are associated with which basis function. This is done by the DofAssignment.

For the DofAssignment, mesh entities are open. This means i.e. the DofAssignment for an edge only knows about basis functions directly associated with the edge and NOT about basis functions associated with the vertices that represent the edge's end points.
