C - the Connection typepublic class DelegatingConnection<C extends java.sql.Connection> 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 and Description |

DelegatingConnection(C c)

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.
