class MeshEdge from SMDS inherits MeshElement from SMDS

	---Purpose: 

is
    Create (ID,idnode1,idnode2: Integer) returns mutable MeshEdge;

    ComputeKey(me: mutable);
    ---Purpose: compute the  ID of the edge  based on the  id's of its
    --          bounding nodes
    ---C++: inline

    GetKey(me) returns Integer is redefined static;    
    ---C++: inline

    GetConnections(me) returns Address is redefined static;
    ---C++: inline

    GetConnection(me; rank: Integer) returns Integer is redefined static;
    ---C++: inline

    SetConnections(me: mutable; idnode1,idnode2: Integer) is private;

    Print(me; OS: in out OStream) is redefined static;
