public class DelegatingConnection extends AbandonedTrace implements java.sql.Connection
Connection
.
All of the methods from the Connection
interface
simply check to see that the Connection
is active,
and call the corresponding method on the "delegate"
provided in my constructor.
Extends AbandonedTrace to implement Connection tracking and logging of code which created the Connection. Tracking the Connection ensures that the AbandonedObjectPool can close this connection and recycle it if its pool of connections is nearing exhaustion and this connection's last usage is older than the removeAbandonedTimeout.
Constructor | Description |
---|---|
DelegatingConnection(java.sql.Connection c) |
Create a wrapper for the Connection which traces this
Connection in the AbandonedObjectPool.
|
DelegatingConnection(java.sql.Connection c,
AbandonedConfig config) |
Create a wrapper for the Connection which traces
the Statements created so that any unclosed Statements
can be closed when this Connection is closed.

Connection
is not a
DelegatingConnection, returns it,
otherwise recursively invokes this method on
my delegate.
Hence this method will return the first delegate that is not a DelegatingConnection, or null when no non-DelegatingConnection delegate can be found by traversing this chain.
This method is useful when you may have nested
DelegatingConnections, and you want to make
sure to obtain a "genuine" Connection
