class SelectPCurves  from IGESSelect    inherits SelectExplore

    ---Purpose : This Selection returns the pcurves which lie on a face
    --           In two modes : global (i.e. a CompositeCurve is not explored)
    --           or basic (all the basic curves are listed)

uses AsciiString from TCollection, Transient, EntityIterator, Graph

is

    Create (basic : Boolean) returns mutable SelectPCurves;
    ---Purpose : Creates a SelectPCurves
    --           basic True  : lists all the components of pcurves
    --           basic False : lists the uppest level definitions
    --             (i.e. stops at CompositeCurve)

    Explore (me; level : Integer; ent : Transient; G : Graph;
    	     explored : in out EntityIterator)
    	returns Boolean;
    ---Purpose : Explores an entity, to take its contained PCurves
    --           An independant curve is IGNORED : only faces are explored

    ExploreLabel (me) returns AsciiString from TCollection;
    ---Purpose : Returns a text defining the criterium : "Basic PCurves" or
    --           "Global PCurves"

fields

    thebasic : Boolean;

end SelectPCurves;
