class DispPerSignature from IFSelect inherits Dispatch
---Purpose : A DispPerSignature sorts input Entities according to a
-- Signature : it works with a SignCounter to do this.

is
Create returns mutable DispPerSignature;
---Purpose : Creates a DispPerSignature with no SignCounter (by default,
-- produces only one packet)
SignCounter (me) returns mutable SignCounter;
---Purpose : Returns the SignCounter used for splitting
SetSignCounter (me : mutable; sign : mutable SignCounter);
---Purpose : Sets a SignCounter for sort
-- Remark : it is set to record lists of entities, not only counts
SignName (me) returns CString;
---Purpose : Returns the name of the SignCounter, which caracterises the
-- sorting criterium for this Dispatch
Label (me) returns AsciiString from TCollection;
---Purpose : Returns as Label, "One File per Signature <name>"
-- -- Evaluation -- --
LimitedMax (me; nbent : Integer; max : out Integer) returns Boolean
is redefined;
---Purpose : Returns True, maximum count is given as <nbent>
-- PacketsCount (me; G : Graph; count : out Integer) returns Boolean
-- is not redefined : Packets must be first determined before counting
Packets (me; G : Graph; packs : in out SubPartsIterator)
raises InterfaceError;
---Purpose : Computes the list of produced Packets. It defines Packets from
-- the SignCounter, which sirts the input Entities per Signature
-- (specific of the SignCounter).
