28 /** LocalTransaction interface provides support for transactions that
29  * are managed internal to an EIS resource manager, and do not require
30  * an external transaction manager.
31  *
32  * <p>A resource adapter implements the javax.resource.spi.LocalTransaction
33  * interface to provide support for local transactions that are performed
34  * on the underlying resource manager.
35  *
36  * <p>If a resource adapter supports the LocalTransaction interface, then
37  * the application server can choose to perform local transaction
38  * optimization (uses local transaction instead of a JTA transaction for
39  * a single resource manager case).
