class TransferWriter from XSControl inherits TShared
---Purpose : TransferWriter gives help to control transfer to write a file
-- after having converted data from Cascade/Imagine
--
-- It works with a Controller (which itself can work with an
-- Actor to Write) and a FinderProcess. It records results and
-- checks
uses Transient,
Shape from TopoDS,
CheckIterator from Interface,
InterfaceModel from Interface,
FinderProcess, Controller, ReturnStatus
is
Create returns mutable TransferWriter;
---Purpose : Creates a TransferWriter, empty, ready to run
-- with an empty FinderProcess (but no controller, etc)
FinderProcess (me) returns mutable FinderProcess;
---Purpose : Returns the FinderProcess itself
SetFinderProcess (me : mutable; FP : mutable FinderProcess);
---Purpose : Sets a new FinderProcess and forgets the former one
Controller (me) returns Controller;
---Purpose : Returns the currently used Controller
SetController (me : mutable; ctl : Controller);
---Purpose : Sets a new Controller, also sets a new FinderProcess
Clear (me : mutable; mode : Integer);
---Purpose : Clears recorded data according a mode
-- 0 clears FinderProcess (results, checks)
-- -1 create a new FinderProcess
TransferMode (me) returns Integer;
---Purpose : Returns the current Transfer Mode (an Integer)
-- It will be interpreted by the Controller to run Transfers
-- This call form could be later replaced by more specific ones
-- (parameters suited for each norm / transfer case)
SetTransferMode (me : mutable; mode : Integer);
---Purpose : Changes the Transfer Mode
PrintStats (me; what : Integer; mode : Integer = 0);
---Purpose : Prints statistics on current Trace File, according what,mode
-- See PrintStatsProcess for details
-- Operations themselves
RecognizeTransient (me : mutable; obj : Transient) returns Boolean;
---Purpose : Tells if a transient object (from an application) is a valid
-- candidate for a transfer to a model
-- Asks the Controller (RecognizeWriteTransient)
-- If <obj> is a HShape, calls RecognizeShape
TransferWriteTransient (me : mutable; model : mutable InterfaceModel;
obj : Transient)
returns ReturnStatus;
---Purpose : Transfers a Transient object (from an application) to a model
-- of current norm, according to the last call to SetTransferMode
-- Works by calling the Controller
-- Returns status : =0 if OK, >0 if error during transfer, <0 if
-- transfer badly initialised
RecognizeShape (me : mutable; shape : Shape from TopoDS) returns Boolean;
---Purpose : Tells if a Shape is valid for a transfer to a model
-- Asks the Controller (RecognizeWriteShape)
TransferWriteShape (me : mutable; model : mutable InterfaceModel;
shape : Shape from TopoDS)
returns ReturnStatus;
---Purpose : Transfers a Shape from CasCade to a model of current norm,
-- according to the last call to SetTransferMode
-- Works by calling the Controller
-- Returns status : =0 if OK, >0 if error during transfer, <0 if
-- transfer badly initialised
CheckList (me) returns CheckIterator;
---Purpose : Returns the check-list of last transfer (write), i.e. the
-- check-list currently recorded in the FinderProcess
ResultCheckList (me; model : InterfaceModel) returns CheckIterator;
---Purpose : Returns the check-list of last transfer (write), but tries
-- to bind to each check, the resulting entity in the model
-- instead of keeping the original Mapper, whenever known
PrintStatsProcess (myclass; TP : FinderProcess;
what : Integer; mode : Integer = 0);
---Purpose : Forecast to print statitics about a FinderProcess
fields
theController : Controller;
theTransferWrite : FinderProcess;
theTransferMode : Integer;
end TransferWriter;
