Class XAXactId
java.lang.Object
org.apache.derby.iapi.store.access.GlobalXact
org.apache.derby.iapi.store.access.xa.XAXactId
- All Implemented Interfaces:
Xid
The XAXactId class is a specific implementation of the JTA Xid interface. It
is only used by the TransactionTable.restore() interface to return an array
of Xid's back to the caller, as part of serving the XAresource.restore()
interface.
It is NOT the object that is stored in the log. One reason for this is that the Formattable and Xid interface's define two different return values for the getFormatId() interface.
