_SubtransactionAwareResourceStub
extends ObjectImpl
implements SubtransactionAwareResource
Recoverable objects that implement nested transaction behavior may support a
specialization of the Resource interface called the SubtransactionAwareResource
interface. A recoverable object can be notified of the completion of a subtransaction by
registering a specialized resource object that offers the SubtransactionAwareResource
interface with the Transaction Service. This registration is done by using the
register_resource or the register_subtran_aware operation of the current Coordinator object.
A recoverable object generally uses the register_resource operation to register a resource
that will participate in the completion of the top-level transaction and the
register_subtran_aware operation to be notified of the completion of a subtransaction.
Certain recoverable objects may want a finer control over the registration in the
completion of a subtransaction. These recoverable objects will use the register_resource
operation to ensure participation in the completion of the top-level transaction and they
will use the register_subtran_aware operation to be notified of the completion of a
particular subtransaction. For example, a recoverable object can use the
register_subtran_aware operation to establish a "committed with respect to" relationship
between transactions; that is, the recoverable object wants to be informed when a
particular subtransaction is committed and then perform certain operations on the
transactions that depend on that transactions completion. This technique could be used
to implement lock inheritance, for example.
The Transaction Service uses the SubtransactionAwareResource interface on each
Resource object registered with a subtransaction. Each object supporting this interface
is implicitly associated with a single subtransaction.
