Detailed Description

Abstract base for one piece of a Selection expression.

A Selection is a comma separated list of components. Each component knows how to answer membership queries for a primitive and its faces, points, and vertices. Path based components match a primitive by path and use explicit index sets. Group based components look up named groups on the primitive.

Whether the component selects the prim as a whole.

Whole prim selection means every face, point, and vertex of a matched prim is implicitly included. Group components consult the primitive group flag for this answer, which is why the prim is required.

Implemented in enzo::GroupSelectionComponent, and enzo::PathSelectionComponent.
