org.eclipse.jetty.io.Connection

A {@link Connection} is associated to an {@link EndPoint} so that I/O eventshappening on the {@link EndPoint} can be processed by the {@link Connection}.

A typical implementation of {@link Connection} overrides {@link #onOpen()} to{@link EndPoint#fillInterested(Callback) set read interest} on the {@link EndPoint}, and when the {@link EndPoint} signals read readyness, this {@link Connection} canread bytes from the network and interpret them.
