- All Implemented Interfaces:
- java.sql.Connection, org.apache.avalon.framework.activity.Disposable, org.apache.avalon.framework.activity.Initializable, org.apache.avalon.framework.logger.LogEnabled, Poolable, Recyclable
- Direct Known Subclasses:
- JdbcConnection
- public abstract class AbstractJdbcConnection
- extends org.apache.avalon.framework.logger.AbstractLogEnabled
- implements java.sql.Connection, Recyclable, org.apache.avalon.framework.activity.Disposable, org.apache.avalon.framework.activity.Initializable
The Connection object used in conjunction with the JdbcDataSource
object.
TODO: Implement a configurable closed end Pool, where the Connection
acts like JDBC PooledConnections work. That means we can limit the
total number of Connection objects that are created.

public AbstractJdbcConnection(java.sql.Connection connection,
boolean oradb)
- Deprecated. Use the version with keepAlive specified
AbstractJdbcConnection
public AbstractJdbcConnection(java.sql.Connection connection,
java.lang.String keepAlive)
- Parameters:
connection
- a driver specific JDBC connection to be wrapped.keepAlive
- a query which will be used to check the statis of the connection after it
has been idle. A null value will cause the keep alive feature to
be disabled.
initialize

- Specified by:
initialize
in interface org.apache.avalon.framework.activity.Initializable
enableLogging
public void enableLogging(org.apache.avalon.framework.logger.Logger log)
- Overrides:

in class org.apache.avalon.framework.logger.AbstractLogEnabled
setPool
protected void setPool(Pool pool)
recycle
public void recycle()
- Description copied from interface:
Recyclable
- This method should be implemented to remove all costly resources
in object. These resources can be object references, database connections,
threads, etc. What is categorised as "costly" resources is determined on
a case by case analysis.
- Specified by:
recycle
in interface Recyclable

throws java.sql.SQLException
- Specified by:
isClosed
in interface java.sql.Connection
close
public void close()
throws java.sql.SQLException
- Specified by:
close
in interface java.sql.Connection
dispose
public void dispose()
- Specified by:
