Interface LocalTransaction
public interface LocalTransaction
The LocalTransaction defines a transaction demarcation interface for
resource manager local transactions. Note that this interface is
used for application level local transaction demarcation. The
system contract level LocalTransaction interface (as defined in
the javax.resource.spi package) is used by the container
for local transaction management.
A local transaction is managed internal to a resource manager. There
is no external transaction manager involved in the coordination of
such transactions.
A CCI implementation can (but is not required to) implement the
LocalTransaction interface. If the LocalTransaction interface is supported
by a CCI implementation, then the method
Connection.getLocalTransaction should return a
LocalTransaction instance. A component can then use the
returned LocalTransaction to demarcate a resource manager local transaction
(associated with the Connection instance) on the underlying EIS
instance.
