Class DisposableConnectionFacade
java.lang.Object
org.apache.tomcat.jdbc.pool.JdbcInterceptor
org.apache.tomcat.jdbc.pool.DisposableConnectionFacade
- All Implemented Interfaces:
- java.lang.reflect.InvocationHandler
public class DisposableConnectionFacade
- extends JdbcInterceptor
A DisposableConnectionFacade object is the top most interceptor that wraps an object of type
PooledConnection
. The ProxyCutOffConnection intercepts two methods:
Connection.close()
- returns the connection to the pool then breaks the link between cutoff and the next interceptor. May be called multiple times.
Object.toString()
- returns a custom string for this object
By default method comparisons is done on a String reference level, unless the PoolConfiguration.setUseEquals(boolean)
has been called
with a true
argument.
