org.apache.derby.iapi.store.access.XATransactionController
This interface allows access to commit,prepare,abort global transactions as part of a two phase commit protocol, during runtime. These interfaces have been chosen to be exact implementations required to implement the XAResource interfaces as part of the JTA standard extension.
It is expected that the following interfaces are only used during the runtime portion of a 2 phase commit connection.
If a runtime exception causes a transaction abort (of a transaction that has not been successfully prepared), then the transaction will act as if xa_rollback() had been called. The transaction will be aborted and any other call other than destroy will throw exceptions.
The XAResource interface is a Java mapping of the industry standard XA resource manager interface. Please refer to: X/Open CAE Specification - Distributed Transaction Processing: The XA Specification, X/Open Document No. XO/CAE/91/300 or ISBN 1 872630 24 3.
NOTE - all calls to this interface assume that the caller has insured that there is no active work being done on the local instance of the transaction in question. RESOLVE - not sure whether this means that the connection associated with the transaction must be closed, or if it just means that synchronization has been provided to provide correct MT behavior from above.
