package IFSelect

    	---Purpose : Gives tools to manage Selecting a group of Entities
    	--           processed by an Interface, for instance to divide up an
    	--           original Model (from a File) to several smaller ones
    	--           They use description of an Interface Model as a graph
    	--           
    	--           Remark that this corresponds to the description of a
    	--           "scenario" of sharing out a File. Parts of this Scenario
    	--           are intended to be permanently stored. IFSelect provides
    	--           the Transient, active counterparts (to run the Scenario).
    	--           But a permanent one (either as Persistent Objects or as
    	--           interpretable Text) must be provided elsewhere.

    enumeration ReturnStatus is  RetVoid, RetDone, RetError, RetFail, RetStop;
    ---Purpose : Qualifies an execution status :
    --           RetVoid  : normal execution which created nothing, or
    --               no data to process
    --           RetDone  : normal execution with a result
    --           RetError : error in command or input data, no execution
    --           RetFail  : execution was run and has failed
    --           RetStop  : indicates end or stop (such as Raise)

    enumeration RemainMode   is
        RemainForget, RemainCompute, RemainDisplay, RemainUndo;
    --  used to pilot SetRemaining from the WorkSession

    enumeration PrintCount   is  ItemsByEntity, CountByItem,  ShortByItem, ListByItem, EntitiesByItem, CountSummary,
    	    	    	    	    GeneralInfo, Mapping, ResultCount;

---Purpose:
-- Lets you choose the manner in which you want to analyze an
-- IGES or STEP file. Your analysis can be either message-oriented or
-- entity-oriented. The specific values are as follows:
-- - ItemsByEntity is a sequential list of all
-- messages per entity of the defined type
-- - CountByItem is the number of entities of the defined
-- type, with their rank number per message
-- - ShortByItem is the number of entities of the defined
-- type, with their types per message; displays the rank
-- numbers of the first five entities of the defined type
-- per message
-- - ListByItem is the number of entities of the defined type
-- per message and the numbers of the entities
-- - EntitiesByItem is the number of entities of the
-- defined type, with their types, rank numbers and
-- Directory Entry numbers per message
-- - GeneralInfo is general information on transfer such as:
--    -      number of entities
--    -      number of roots
--    -      number of resulting Open CASCADE shapes
--    -      number of warnings and failures
--    -      CountSummary summary statistics for counters and signatures
--    -      ResultCount information that contains the number of
--       roots in the IGES file and the number of resulting Open CASCADE shapes.
  --  -       Mapping of the IGES root entities to the resulting Open
    --   CASCADE shape (including type and form of the IGES entity
      -- and type of the resulting shape). 

    enumeration PrintFail   is FailOnly, FailAndWarn;
    ---Purpose: Indicates whether there will
-- be information on warnings as well as on failures. The
-- terms of this enumeration have the following semantics:
-- - IFSelect_FailOnly gives information on failures only
-- - IFSelect_FailAndWarn gives information on both
--   failures and warnings. used to pilot PrintCheckList
    enumeration EditValue    is
    	Optional, Editable, EditProtected, EditComputed, EditRead, EditDynamic;
    ---Purpose : Controls access on Values by an Editor
    --           EditOptional  : normal access, in addition may be removed
    --           Editable      : normal access, must be present
    --           EditProtected : access must be validated
    --           EditComputed  : why write it ?  it will be recomputed
    --           EditRead      : no way to write it, only for read
    --           EditDynamic   : not a field, only to be displayed

    	-- --    Instantiations    -- --

    class TSeqOfDispatch  instantiates  Sequence from TCollection (Dispatch);
    class TSeqOfSelection instantiates  Sequence from TCollection (Selection);
    class HSeqOfSelection instantiates HSequence from TCollection
    	(Selection,TSeqOfSelection);

    -- the followings sequences are used by ModelCopier (definition or result)
    class SequenceOfGeneralModifier  instantiates Sequence from TCollection
        (GeneralModifier);
    class SequenceOfInterfaceModel   instantiates Sequence from TCollection
        (InterfaceModel from Interface);
    class SequenceOfAppliedModifiers instantiates Sequence from TCollection
    	(AppliedModifiers);

    	--   Package Methods   --

    SaveSession (WS : any WorkSession; file : CString) returns Boolean;
    ---Purpose : Saves the state of a WorkSession from IFSelect, by using a
    --           SessionFile from IFSelect. Returns True if Done, False in
    --           case of Error on Writing. <file> gives the name of the File
    --           to be produced (this avoids to export the class SessionFile).

    RestoreSession (WS : mutable WorkSession; file : CString) returns Boolean;
    ---Purpose : Restore the state of a WorkSession from IFSelect, by using a
    --           SessionFile from IFSelect. Returns True if Done, False in
    --           case of Error on Writing. <file> gives the name of the File
    --           to be used (this avoids to export the class SessionFile).
