RAD Studio VCL Reference
|
|
|
Instantiates a TransactionContextEx object, which marks the beginning of a transaction.
function CreateTransactionContextEx: ITransactionContextEx;
ITransactionContextEx CreateTransactionContextEx();
MTS base clients use CreateTransactionEx to combine the work of one or more MTS objects into an atomic transaction and to commit or abort the transaction. Clients initiate a transaction by instantiating a CreateTransactionEx object. Clients end a transaction by calling Complete or Abort on the object.

Method |
Description |
|
Abort |
Aborts the work of all MTS objects participating in the current transaction. The transaction is completed on return from this method. |
|
Commit |
Attempts to commit the work of all MTS objects participating in the current transaction. If any of the MTS objects participating in the transaction call SetAbort or DisableCommit, or if a system error occurs, the transaction is aborted. Otherwise, the transaction is committed. In either case, the transaction is completed on return from this method. |
|
CreateInstance |
Instantiates another MTS object. If the component that provides the object is configured to support or require a transaction, then the new object runs under the transaction of the TransactionContextEx object. |
