class MultipleBinder from Transfer inherits Binder
|
|
|
|
---Purpose : Allows direct binding between a starting Object and the Result
|
|
-- of its transfer, when it can be made of several Transient
|
|
-- Objects. Compared to a Transcriptor, it has no Transfer Action
|
|
--
|
|
-- Result is a list of Transient Results. Unique Result is not
|
|
-- available : SetResult is redefined to start the list on the
|
|
-- first call, and refuse the other times.
|
|
--
|
|
-- rr
|
|
--
|
|
-- Remark : MultipleBinder itself is intended to be created and
|
|
-- filled by TransferProcess itself (method Bind). In particular,
|
|
-- conflicts between Unique (Standard) result and Multiple result
|
|
-- are avoided through management made by TransferProcess.
|
|
--
|
|
-- Also, a Transcriptor (with an effective Transfer Method) which
|
|
-- can produce a Multiple Result, may be defined as a sub-class
|
|
-- of MultipleBinder by redefining method Transfer.

---Purpose : normal standard constructor, creates an empty MultipleBinder
