class DispPerCount from IFSelect inherits Dispatch
---Purpose : A DispPerCount gathers all the input Entities into one or
-- several Packets, each containing a defined count of Entity
-- This count is a Parameter of the DispPerCount, given as an
-- IntParam, thus allowing external control of its Value
uses AsciiString from TCollection, Graph, SubPartsIterator, IntParam
raises InterfaceError
is
Create returns mutable DispPerCount;
---Purpose : Creates a DispPerCount with no Count (default value 1)
Count (me) returns mutable IntParam;
---Purpose : Returns the Count Parameter used for splitting
SetCount (me : mutable; count : mutable IntParam);
---Purpose : Sets a new Parameter for Count
CountValue (me) returns Integer;
---Purpose : Returns the effective value of the count parameter
-- (if Count Parameter not Set or value not positive, returns 1)
Label (me) returns AsciiString from TCollection;
---Purpose : Returns as Label, "One File per <count> Input Entities"
-- -- 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 redefined;
---Purpose : Returns True (count is easy to know) and count is computed
-- from length of input list (RootResult from Final Selection)
Packets (me; G : Graph; packs : in out SubPartsIterator)
raises InterfaceError;
---Purpose : Computes the list of produced Packets. It defines Packets in
-- order to have at most <Count> Entities per Packet, Entities
-- are given by RootResult from the Final Selection.
