java.lang.Object
org.logicalcobwebs.proxool.util.AbstractListenerContainer
org.logicalcobwebs.proxool.CompositeConnectionListener
- All Implemented Interfaces:
- ConnectionListenerIF, ListenerContainerIF
public class CompositeConnectionListener
- extends AbstractListenerContainer
- implements ConnectionListenerIF
A ConnectionListenerIF
that keeps a list of ConnectionListenerIF
s
and notifies them in a thread safe manner.
It also implements ListenerContainerIF
which provides methods for
adding
and
removing
listeners.

public CompositeConnectionListener()
onBirth
public void onBirth(java.sql.Connection connection)
throws java.sql.SQLException
- Description copied from interface:
ConnectionListenerIF

to allocate resources to a connection that might be useful during
the lifetime of the connection.
- Specified by:
onBirth
in interface ConnectionListenerIF
- Parameters:
connection
- the connection that has just been created
- Throws:
java.sql.SQLException
- if anything goes wrong (which will then be logged but ignored)- See Also:
ConnectionListenerIF.onBirth(Connection)
onDeath
public void onDeath(java.sql.Connection connection)
throws java.sql.SQLException
- Description copied from interface:
ConnectionListenerIF
- Happens just before we expire a connection. You can use this to
reclaim resources from a connection.
- Specified by:
onDeath
in interface ConnectionListenerIF
- Parameters:
connection
- the connection that is about to expire
- Throws:
java.sql.SQLException
- if anything goes wrong (which will then be logged but ignored)- See Also:

long elapsedTime)
- Description copied from interface:
ConnectionListenerIF
- Happens after every successful execute. Note that the command
is not fully implemented at this stage. At some point it might represent
the SQL that is sent to the database (or the procedure call that was used).
