	Prerequesite for Transfer : the method Transfer is called on a starting object only if Recognize has returned True on it This allows to define a list of Actors, each one processing a definite kind of data TransferProcess calls Recognize on each one before calling Transfer. But even if Recognize has returned True, Transfer can reject by returning a Null Binder (afterwards rejection), the next actor is then invoked.

virtual Handle< Transfer_Binder >	Transferring (const Handle< Standard_Transient > &start, const Handle< Transfer_ProcessForTransient > &TP, const Message_ProgressRange &theProgress=Message_ProgressRange()) override
	Specific action of Transfer. The Result is stored in the returned Binder, or a Null Handle for "No result" (Default defined as doing nothing; should be deferred) "mutable" allows the Actor to record intermediate information, in addition to those of TransferProcess.

Public Member Functions inherited from Transfer_ActorOfProcessForTransient
	Transfer_ActorOfProcessForTransient ()
Handle< Transfer_SimpleBinderOfTransient >	TransientResult (const Handle< Standard_Transient > &res) const
	Prepares and Returns a Binder for a Transient Result Returns a Null Handle if <res> is itself Null.
Handle< Transfer_Binder >	NullResult () const
	Returns a Binder for No Result, i.e. a Null Handle.
void	SetLast (const Standard_Boolean mode=Standard_True)
	If <mode> is True, commands an Actor to be set at the end of the list of Actors (see SetNext) If it is False (creation default), each add Actor is set at the beginning of the list This allows to define default Actors (which are Last)
Standard_Boolean	IsLast () const
	Returns the Last status (see SetLast).
void	SetNext (const Handle< Transfer_ActorOfProcessForTransient > &next)
	Defines a Next Actor : it can then be asked to work if <me> produces no result for a given type of Object. If Next is already set and is not "Last", calls SetNext on it. If Next defined and "Last", the new actor is added before it in the list.
Handle< Transfer_ActorOfProcessForTransient >	Next () const
	Returns the Actor defined as Next, or a Null Handle.

Detailed Description

This class performs the transfer of an Entity from AP214 and AP203, either Geometric or Topologic.

I.E. for each type of Entity, it invokes the appropriate Tool then returns the Binder which contains the Result
