Table class.
Library: dataccess
The IliTransactionManager
class manages so-called local transactions where one or more IliTable
objects can defer the propagation of changes they undergo until a later function call occurs. The transaction manager is responsible for recording all these changes as they happen so that it can do one of the following:
-
Revert the
IliTable
objects to their initial state if the transaction is canceled.
-
Direct the
IliTable
objects to propagate these changes to their remote storage manager. (This applies only to two-tier table objects.)
- See also
IliTable
.
Accessors\nAccessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods <tt>IlvValueInterface::queryValue()</tt>, <tt>IlvValueInterface::queryValues()</tt>, <tt>IlvValueInterface::changeValue()</tt>, <tt>IlvValueInterface::changeValues()</tt>.\n\nThis class defines the following accessors:
Data accessors
Method accessors
[start]: The following Rogue Wave Views Script code assigns the same transaction manager to two given IliTable
objects and then starts the transaction manager:
var tbl_EMP = IliRepository.EMP_DS.table;
var tbl_DEPT = IliRepository.DEPT_DS.table;
tbl_EMP.transactionManagerName = 'TM_1';
tbl_DEPT.transactionManagerName = 'TM_1';
var tm = tbl_EMP.transactionManager;
tm.start();
[errorSink]: The sink parameter can be one of the following:
-
An
IliErrorList
object var errList = new IliErrorList();
tm.addErrorSink(errList);
-
An
IliObserver
object whose func property contains a Rogue Wave Views Script function having the following signature: fct(IliErrorMessage msg)
function OnError(msg) {
writeln(msg.prettyMessage);
}
tm.addErrorSink(new IliObserver(OnError));
Accepts all recorded events.
This typically involves having all two-tier tables propagate updates to their remote storage manager. If successful, the event count is reset to 0
. Otherwise, the event count remains unchanged. Note that if a two-tier table (such as an IliSQLTable
object) is involved in one or more of the events, a rollback should be issued by the user to its SQL session or else the state of the database transaction may become inconsistent with the state of the IliSQLTable
object. Events are accepted in order of occurrence (from the oldest to the most recent). In the case where one event fails, no attempt is made to accept the subsequent events in the chain and IlFalse
is immediately returned.
- Returns
IlTrue
if successful.
