Class XAClientConnection
java.lang.Object
|
+--org.jboss.minerva.xa.XAClientConnection
- All Implemented Interfaces:
- java.sql.Connection, ConnectionWrapper
- public class XAClientConnection
- extends java.lang.Object
- implements ConnectionWrapper
Wrapper for database connections used by an XAConnection. When close is
called, it does not close the underlying connection, just informs the
XAConnection that close was called. The connection will not be closed (or
returned to the pool) until the transactional details are taken care of.
This instance only lives as long as one client is using it - though we
probably want to consider reusing it to save object allocations.

XAClientConnection
public XAClientConnection(XAConnectionImpl xaCon,
java.sql.Connection con)
- Creates a new connection wrapper.
- Parameters:
xaCon
- The handler for all the transactional details.con
- The "real" database connection to wrap.
getUnderlyingConnection
public java.sql.Connection getUnderlyingConnection()
- Gets a reference to the "real" connection. This should only be used if
you need to cast that to a specific type to call a proprietary method -
you will defeat all the pooling if you use the underlying connection
directly.
shutdown
public void shutdown()
- Closes this connection wrapper permanently. All further calls with throw
a SQLException.
setLastUsed
public void setLastUsed()
- Updates the last used time for this connection to the current time.
This is not used by the current implementation.
- Specified by:
setLastUsed
in interface ConnectionWrapper
setError
public void setError(java.sql.SQLException e)
- Indicates that an error occured on this connection.
- Specified by:
setError
in interface ConnectionWrapper
statementClosed
public void statementClosed(java.sql.Statement st)
- Indicates that a statement has been closed and no longer needs to be
tracked. Outstanding statements are closed when the connection is
returned to the pool.

statementClosed
