Interface Xid
public interface Xid
The Xid interface is a Java mapping of the X/Open transaction identifier
XID structure. This interface specifies three accessor methods to
retrieve a global transaction format ID, global transaction ID,
and branch qualifier. The Xid interface is used by the transaction
manager and the resource managers. This interface is not visible to
the application programs.
