class GraphCounter  from IFSelect    inherits SignCounter  from IFSelect

    ---Purpose : A GraphCounter computes values to be sorted with the help of
    --           a Graph. I.E. not from a Signature
    --           
    --           The default GraphCounter works with an Applied Selection (a
    --           SelectDeduct), the value is the count of selected entities
    --           from each input entities)

uses HSequenceOfTransient from TColStd,
     Graph from Interface, SelectDeduct from IFSelect

is

    Create (withmap  : Boolean = Standard_True;
            withlist : Boolean = Standard_False) returns mutable GraphCounter;
    ---Purpose : Creates a GraphCounter, without applied selection

    Applied (me) returns SelectDeduct;
    ---Purpose : Returns the applied selection

    SetApplied (me : mutable; sel : SelectDeduct);
    ---Purpose : Sets a new applied selection

    AddWithGraph (me : mutable; list : HSequenceOfTransient; graph : Graph)
        is redefined virtual;
    ---Purpose : Adds a list of entities in the context given by the graph
    --           Default takes the count of entities selected by the applied
    --           selection, when it is given each entity of the list
    --           Can be redefined

fields

    theapplied : SelectDeduct;

end GraphCounter;
