class SelectBypassGroup  from IGESSelect  inherits SelectExplore

    ---Purpose : Selects a list built as follows :
    --           Groups are entities type 402, forms 1,7,14,15 (Group,
    --           Ordered or not, "WithoutBackPointer" or not)
    --           
    --           Entities which are not GROUP are taken as such
    --           For Groups, their list of Elements is explore
    --           Hence, level 0 (D) recursively explores a Group if some of
    --           its Elements are Groups. level 1 explores just at first level

uses AsciiString from TCollection, Transient, EntityIterator, Graph

raises InterfaceError

is

    Create (level : Integer = 0) returns SelectBypassGroup;
    ---Purpose : Creates a SelectBypassGroup, by default all level
    --           (level = 1 explores at first level)

    Explore (me; level : Integer; ent : Transient; G : Graph;
    	     explored : in out EntityIterator)
    	returns Boolean;
    ---Purpose : Explores an entity : for a Group, gives its elements
    --           Else, takes the entity itself
