class Transform from SMDSEdit 

	---Purpose: tool to modify  a Mesh or MeshElements by applying
	--          a transformation

uses
  Mesh from SMDS,
  ListOfMeshElement from SMDS,
  Trsf from gp
  
is
    Create (aMesh : Mesh from SMDS; aTrsf: Trsf from gp) 
    returns Transform from SMDSEdit;
    ---Purpose: create a transform tool on a whole mesh

    Create (aMesh : Mesh from SMDS; aListOfME : ListOfMeshElement from SMDS;
    	    aTrsf : Trsf from gp)
    returns Transform from SMDSEdit;
    ---Purpose: create  a transform  tool to be  applied on a  list of
    --          meshelements from the mesh aMesh. MeshElements from the
    --          list that do not belong to the mesh will not be treated

    Perform (me: in out);
    ---Purpose: Perform  the current transformation on the  Mesh or on
    --          the list of meshelements if it is not empty
    
    SetTrsf(me: in out; aTrsf: Trsf from gp);
    ---Purpose: replace the field myTrsf by the one given in argument
    --          This can be used to apply another transformation on a mesh
    --          without creating another instance of SMDSEdit_Transform

    GetTrsf(me) returns Trsf from gp;
    ---Purpose: returns the stored Trsf
     
    
fields
    myMesh     : Mesh from SMDS;
    myTrsf     : Trsf from gp;
    myListOfME : ListOfMeshElement from SMDS;
end Transform;
