	Returns the Type permitted for Results, i.e. here Transient.

	Returns the value of the recorded result n0 <num>

	Returns the Multiple Result, if it is defined (at least one Item). Else, returns a Null Handle.

void	SetMultipleResult (const occ::handle< NCollection_HSequence< occ::handle< Standard_Transient > > > &mulres)
	Defines a Binding with a Multiple Result, given as a Sequence Error if a Unique Result has yet been defined.

Public Member Functions inherited from Transfer_Binder
void	Merge (const occ::handle< Transfer_Binder > &other)
	Merges basic data (Check, ExecStatus) from another Binder but keeps its result. Used when a binder is replaced by another one, this allows to keep messages.

void	AddResult (const occ::handle< Transfer_Binder > &next)
	Adds a next result (at the end of the list) Remark : this information is not processed by Merge.

occ::handle< Transfer_Binder >	NextResult () const
	Returns the next result, Null if none.

bool	HasResult () const
	Returns True if a Result is available (StatusResult = Defined) A Unique Result will be gotten by Result (which must be defined in each sub-class according to result type) For a Multiple Result, see class MultipleBinder For other case, specific access has to be forecast.

void	SetAlreadyUsed ()
	Declares that result is now used by another one, it means that it cannot be modified (by Rebind)

Transfer_StatusResult	Status () const
	Returns status, which can be Initial (not yet done), Made (a result is recorded, not yet shared), Used (it is shared and cannot be modified)

Transfer_StatusExec	StatusExec () const
	Returns execution status.

void	SetStatusExec (const Transfer_StatusExec stat)
	Modifies execution status; called by TransferProcess only (for StatusError, rather use SetError, below)

void	AddFail (const char const mess, const char const orig="")
	Used to declare an individual transfer as being erroneous (Status is set to Void, StatusExec is set to Error, <errmess> is added to Check's list of Fails) It is possible to record several messages of error.

void	AddWarning (const char const mess, const char const orig="")
	Used to attach a Warning Message to an individual Transfer It has no effect on the Status.

const occ::handle< Interface_Check >	Check () const
	Returns Check which stores Fail messages Note that no Entity is associated in this Check.

occ::handle< Interface_Check >	CCheck ()
	Returns Check which stores Fail messages, in order to modify it (adding messages, or replacing it)

	~Transfer_Binder () override
	Destructor.

Public Member Functions inherited from Standard_Transient
	Standard_Transient ()
	Empty constructor.

	Standard_Transient (const Standard_Transient &)
	Copy constructor – does nothing.

Standard_Transient &	operator= (const Standard_Transient &)
	Assignment operator, needed to avoid copying reference counter.

virtual	~Standard_Transient ()=default
	Destructor must be virtual.

virtual const opencascade::handle< Standard_Type > &	DynamicType () const
	Returns a type descriptor about this object.

bool	IsInstance (const opencascade::handle< Standard_Type > &theType) const
	Returns a true value if this is an instance of Type.

bool	IsInstance (const char *const theTypeName) const
	Returns a true value if this is an instance of TypeName.

bool	IsKind (const opencascade::handle< Standard_Type > &theType) const
	Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.

bool	IsKind (const char *const theTypeName) const
	Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.

Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.

int	GetRefCount () const noexcept
	Get the reference counter of this object.

void	IncrementRefCounter () noexcept
	Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.

int	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.

virtual void	Delete () const
	Memory deallocator for transient classes.

Additional Inherited Members
Public Types inherited from Standard_Transient
typedef void	base_type
	Returns a type descriptor about this object.

Static Public Member Functions inherited from Standard_Transient
static constexpr const char *	get_type_name ()
	Returns a type descriptor about this object.

static const opencascade::handle< Standard_Type > &	get_type_descriptor ()
	Returns type descriptor of Standard_Transient class.

Protected Member Functions inherited from Transfer_Binder
	Transfer_Binder ()
	Sets fields at initial values.

void	SetResultPresent ()
	Used to declare that a result is recorded for an individual transfer (works by setting StatusResult to Defined)

Detailed Description

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.
