Class JDBCXAConnection

java.lang.Object

org.hsqldb.jdbc.pool.JDBCPooledConnection

org.hsqldb.jdbc.pool.JDBCXAConnection

All Implemented Interfaces:

javax.sql.PooledConnection, javax.sql.XAConnection, JDBCConnectionEventListener

public class JDBCXAConnection
extends JDBCPooledConnection
implements javax.sql.XAConnection

Subclass of JDBCPooledConnection implements the XAConnection interface. For use by global transaction service managers.

Each instance has an JDBCXAResource inherits the superclass's two JDBCConnection objects, one for internal access, and one for user access.

The getConnection() method returns a user connection and links this with the JDBCXAResource. This puts the object in the inUse state. When the user connection is closed, the object is put in the free state.

Since:

HSQLDB 2.0
