Examples of org.apache.tomcat.dbcp.dbcp2.DelegatingConnection

org.apache.tomcat.dbcp.dbcp2.SwallowedExceptionLogger
A base delegating implementation of {@link Connection}.
All of the methods from the {@link Connection} interfacesimply check to see that the {@link 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. @param < C> the Connection type @author Rodney Waldhoff @author Glenn L.
