/** Abstract Connection used by Jetty Connectors.
 * 

* Jetty will call the handle method of a connection when there is work * to be done on the connection. For blocking connections, this is soon * as the connection is open and handle will keep being called until the * connection is closed. For non-blocking connections, handle will only * be called if there are bytes to be read or the connection becomes writable * after being write blocked. * * @see org.eclipse.jetty.io.nio.SelectorManager */ public interface Connection { /* ------------------------------------------------------------ */ /** * Handle the connection. * @return The Connection to use for the next handling of the connection. * This allows protocol upgrades and support for CONNECT. * @throws IOException if the handling of I/O operations fail */ Connection handle() throws IOException; /** * @return the timestamp at which the connection was created */ long getTimeStamp(); /** * @return whether this connection is idle, that is not parsing and not generating * @see #onIdleExpired(long) */ boolean isIdle(); /** *

The semantic of this method is to return true to indicate interest in further reads, * or false otherwise, but it is misnamed and should be really called isReadInterested().

* * @return true to indicate interest in further reads, false otherwise */ // TODO: rename to isReadInterested() in the next release boolean isSuspended(); /** * Called after the connection is closed */ void onClose(); /** * Called when the connection idle timeout expires * @param idleForMs how long the connection has been idle * @see #isIdle() */ void onIdleExpired(long idleForMs); }
