uses
    MeshElement from SMDS

is

    Create (ID, idnode1,idnode2,idnode3: Integer) returns mutable MeshTriangle;
    	---Purpose: constructor for a triangle
    
    ComputeKey(me: mutable) is redefined static;
    ---Purpose: compute the  ID of the face  based on the  id's of its
    --          bounding nodes
    ---C++: inline

    GetEdgeDefinedByNodes(me; rank: Integer; idnode1, idnode2 : out Integer) 
    is redefined static;
    ---Purpose: returns the idnodes of the ith edge (rank) of the face
    --          rank must be comprised between 1 and myNbConnections included.
