Class
    Foam::meshObjects
 
Description
    Templated abstract base-class for optional mesh objects used to automate
    their allocation to the mesh database and the mesh-modifier event-loop.
 
    MeshObject is templated on the type of mesh it is allocated to, the type of
    the mesh object (DeletableMeshObject, MoveableMeshObject,
    DistributeableMeshObject, TopoChangeableMeshObject) and the type of the
    actual object it is created for example:
 
    \verbatim
    class leastSquaresVectors
    :
        public MeshObject<fvMesh, MoveableMeshObject, leastSquaresVectors>
    {
    .
    .
    .
        //- Delete the least square vectors when the mesh moves
        virtual bool movePoints();
    };
    \endverbatim
 
    MeshObject types:
 
    - DeletableMeshObject:
        mesh object to be deleted after any mesh change
    - MoveableMeshObject:
        mesh object to be updated after mesh motion otherwise deleted
    - DistributeableMeshObject
        mesh object to be updated after mesh redistribution or motion
        otherwise deleted
    - TopoChangeableMeshObject:
        mesh object to be updated after mesh topology change,
        mesh-to-mesh mapping, redistribution or motion otherwise deleted
    - RepatchableMeshObject:
        mesh object to be updated on patch or topology change,
        mesh-to-mesh mapping, redistribution or motion otherwise deleted
 
    Note:
        movePoints must be provided for MeshObjects of type MoveableMeshObject
        and both movePoints and topoChange functions must exist, provided for
        MeshObjects of type TopoChangeableMeshObject.
