   example.ManagedConnectionImpl

ManagedConnectionImpl
public class ManagedConnectionImpl implements ManagedConnection(Code)
ManagedConnectionImpl represents the underlying (SPI) connection to the resource. Resin will manage this ManagedConnection in its pool. The user will see the ConnectionImpl facade and may not even know that the ManagedConnectionImpl exists.



Constructor Summary
 ManagedConnectionImpl(String name, ManagedConnectionFactoryImpl factory)
     Creates a new ManagedConnection with its id.

Method Summary
public  voidaddConnectionEventListener(ConnectionEventListener listener)
     Resin will register a listener with the ManagedConnection so it will know when a connection closes or has a fatal error.
public  voidassociateConnection(Object conn)
     XXX:??? In some cases, Resin can associate an old application connection with the ManagedConnection.
public  voidcleanup()
     Called when Resin returns a connection to the idle pool.
 voidclose(ConnectionImpl conn)
     Implementation method to allow the ConnectionImpl to trigger Resin's listeners when the connection closes.
public  voiddestroy()
     Called when Resin is closing the connection.
public  ObjectgetConnection(Subject subject, ConnectionRequestInfo info)
     Creates a new application connection.
public  LocalTransactiongetLocalTransaction()
     Transaction-aware resources will return the LocalTransaction for the managed connection.
public  PrintWritergetLogWriter()
     Logging should use JDK 1.4 java.util.logging.
public  ManagedConnectionMetaDatagetMetaData()
     This example isn't returning any meta data.
public  XAResourcegetXAResource()
     Transaction-aware resources will return the XAResource for the managed connection.
public  voidremoveConnectionEventListener(ConnectionEventListener listener)
     Resin can remove it's listener when it removes the managed connection from the pool.
public  voidsetLogWriter(PrintWriter log)
     Logging should use JDK 1.4 java.util.logging.
public  StringtoString()
    


Constructor Detail
ManagedConnectionImpl
ManagedConnectionImpl(String name, ManagedConnectionFactoryImpl factory)(Code)
Creates a new ManagedConnection with its id. ManagedConnectionFactoryImpl will create the ManagedConnectionImpl in response to a Resin request.




Method Detail
addConnectionEventListener
public void addConnectionEventListener(ConnectionEventListener listener)(Code)
Resin will register a listener with the ManagedConnection so it will know when a connection closes or has a fatal error.
Parameters:
  listener - Resin's listener to receive notice of a close.



associateConnection
public void associateConnection(Object conn)(Code)
XXX:??? In some cases, Resin can associate an old application connection with the ManagedConnection. (I'm not sure when this can happen.)
Parameters:
  conn - the application view of the connection



cleanup
public void cleanup()(Code)
Called when Resin returns a connection to the idle pool.



close
void close(ConnectionImpl conn)(Code)
Implementation method to allow the ConnectionImpl to trigger Resin's listeners when the connection closes.
Parameters:
  conn - the user connection which is closing.



destroy
public void destroy()(Code)
Called when Resin is closing the connection. Any sockets, etc, would be closed here.



getConnection
public Object getConnection(Subject subject, ConnectionRequestInfo info)(Code)
Creates a new application connection. The application connection will be in use until its close() method is called. It's close method will call the ConnectionEventListener registered with this ManagedConnectionImpl instance. It is important for the connection's close to be called and for the connection to call the close listeners, because Resin needs to know when the application is done with the connection and Resin can return the ManagedConnection to the pool.
Parameters:
  subject - the subject for the connection
Parameters:
  info - the connection information for the connection the application-view of the connection



getLocalTransaction
public LocalTransaction getLocalTransaction()(Code)
Transaction-aware resources will return the LocalTransaction for the managed connection. LocalTransaction is a lightweight interface for transactions that don't need the full XA transactions.



getLogWriter
public PrintWriter getLogWriter()(Code)
Logging should use JDK 1.4 java.util.logging.



getMetaData
public ManagedConnectionMetaData getMetaData()(Code)
This example isn't returning any meta data. In general, providing the meta data is nice for the applications.



getXAResource
public XAResource getXAResource()(Code)
Transaction-aware resources will return the XAResource for the managed connection.



removeConnectionEventListener
public void removeConnectionEventListener(ConnectionEventListener listener)(Code)
Resin can remove it's listener when it removes the managed connection from the pool.
Parameters:
  listener - Resin's listener to receive notice of a close.



setLogWriter
public void setLogWriter(PrintWriter log)(Code)
Logging should use JDK 1.4 java.util.logging.



toString
public String toString()(Code)
