deferred class SelectExtract  from IFSelect  inherits SelectDeduct

    ---Purpose : A SelectExtract determines a list of Entities from an Input
    --           Selection, as a sub-list of the Input Result
    --           It works by applying a sort criterium on each Entity of the
    --           Input. This criterium can be applied Direct to Pick Items
    --           (default case) or Reverse to Remove Item
    --           
    --           Basic features (the unique Input) are inherited from SelectDeduct

uses AsciiString from TCollection, InterfaceModel, EntityIterator,  Graph

is

    Initialize;
    ---Purpose : Initializes a SelectExtract : enforces the sort to be Direct

    IsDirect (me) returns Boolean;
    ---Purpose : Returns True if Sort criterium is Direct, False if Reverse

    SetDirect (me : mutable; direct : Boolean);
    ---Purpose : Sets Sort criterium sense to a new value
    --           (True : Direct , False : Reverse)

    	-- Input : see SelectDeduct


    RootResult (me; G : Graph) returns EntityIterator is virtual;
    ---Purpose : Returns the list of selected entities. Works by calling the
    --           method Sort on each input Entity : the Entity is kept as
    --           output if Sort returns the same value as Direct status

    Sort (me; rank : Integer; ent : Transient; model : InterfaceModel)
    	returns Boolean  is deferred;
    ---Purpose : Returns True for an Entity if it satisfies the Sort criterium
    --           It receives :
    --           - <rank>, the rank of the Entity in the Iteration,
    --           - <ent> , the Entity itself, and
    --           - <model>, the Starting Model
    --             Hence, the Entity to check is "model->Value(num)" (but an
    --             InterfaceModel allows other checks)
    --           This method is specific to each class of SelectExtract

    SortInGraph (me; rank : Integer; ent : Transient; G : Graph)
    	returns Boolean  is virtual;
    ---Purpose : Works as Sort but works on the Graph
    --           Default directly calls Sort, but it can be redefined
    --           If SortInGraph is redefined, Sort should be defined even if
    --           not called (to avoid deferred methods in a final class)


    Label (me) returns AsciiString from TCollection;
    ---Purpose : Returns a text saying "Picked" or "Removed", plus the
    --           specific criterium returned by ExtractLabel (see below)

    ExtractLabel (me) returns AsciiString from TCollection  is deferred;
    ---Purpose : Returns a text defining the criterium for extraction

    thesort : Boolean;
