Detailed Description
A Binder is an auxiliary object to Map the Result of the Transfer of a given Object : it records the Result of the Unitary Transfer (Resulting Object), status of progress and error (if any) of the Process.
The class Binder itself makes no definition for the Result : it is defined by sub-classes : it can be either Simple (and has to be typed : see generic class SimpleBinder) or Multiple (see class MultipleBinder).
In principle, for a Transfer in progress, Result cannot be accessed : this would cause an exception raising. This is controlled by the value if StatusResult : if it is "Used", the Result cannot be changed. This status is normally controlled by TransferProcess but can be directly (see method SetAlreadyUsed)
Checks can be completed by a record of cases, as string which can be used as codes, but not to be printed
In addition to the Result, a Binder can bring a list of Attributes, which are additional data, each of them has a name

Sets fields at initial values.
Member Function Documentation
| void Transfer_Binder::AddFail | ( | const Standard_CString | mess, |
| const Standard_CString | orig = "" |
||
| ) |
Used to declare an individual transfer as beeing 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.
It has same effect for TransferProcess as raising an exception during the operation of Transfer, except the Transfer tries to continue (as if ErrorHandle had been set)
| void Transfer_Binder::AddResult | ( | const Handle< Transfer_Binder > & | next | ) |
Adds a next result (at the end of the list) Remark : this information is not processed by Merge.
| void Transfer_Binder::AddWarning | ( | const Standard_CString | mess, |
| const Standard_CString | orig = "" |
||
| ) |
Used to attach a Warning Message to an individual Transfer It has no effect on the Status.
| Handle< Interface_Check > Transfer_Binder::CCheck | ( | ) |
Returns Check which stores Fail messages, in order to modify it (adding messages, or replacing it)
| const Handle< Interface_Check > Transfer_Binder::Check | ( | ) | const |
Returns Check which stores Fail messages Note that no Entity is associated in this Check.
| Standard_Boolean Transfer_Binder::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.
|
virtual |
Returns True if a Binder has several results, either by itself or because it has next results Can be defined by sub-classes.
Reimplemented in Transfer_MultipleBinder, TransferBRep_ShapeListBinder, and Transfer_TransientListBinder.
| void Transfer_Binder::Merge | ( | const 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.
| Handle< Transfer_Binder > Transfer_Binder::NextResult | ( | ) | const |
Returns the next result, Null if none.
|
pure virtual |
Returns the Type which characterizes the Result (if known)
Implemented in Transfer_MultipleBinder, TransferBRep_ShapeListBinder, TransferBRep_BinderOfShape, Transfer_TransientListBinder, Transfer_SimpleBinderOfTransient, and Transfer_VoidBinder.
|
pure virtual |
Returns the Name of the Type which characterizes the Result Can be returned even if ResultType itself is unknown.
Implemented in Transfer_MultipleBinder, TransferBRep_ShapeListBinder, TransferBRep_BinderOfShape, Transfer_SimpleBinderOfTransient, Transfer_TransientListBinder, and Transfer_VoidBinder.
| void Transfer_Binder::SetAlreadyUsed | ( | ) |
Declares that result is now used by another one, it means that it cannot be modified (by Rebind)
|
protected |
Used to declare that a result is recorded for an individual transfer (works by setting StatusResult to Defined)
This Method is to be called once a Result is really recorded (see sub-classes of Binder, especially SimpleBinder) : it is senseless if called isolately
| void Transfer_Binder::SetStatusExec | ( | const Transfer_StatusExec | stat | ) |
Modifies execution status; called by TransferProcess only (for StatusError, rather use SetError, below)
| Transfer_StatusResult Transfer_Binder::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 Transfer_Binder::StatusExec | ( | ) | const |
Returns execution status.
