Java Browser APIs

Java cmlog browser uses event listener model to handle server response. There are 3 event listener interfaces: BrowserDisconnectEventListener, BrowserMonitorEventListener and BrowserQueryEventListener. The first one handles disconnection event, the second one handles all incoming logging messages and the other one handles returned results of a query. All three interfaces have similar interface functions that need to be implemented by applications. Those functions take one argument of BrowserEvent which contains a server reply in a form Packet. The cdevData can be retrieved from the packet.

• connect (java.lang.String host, int port)
  • Description

    Connect to a cmlog server.

• disconnect ()
  • Description

    Disconnect from a cmlog server.

• addDisconnectEventListener(BrowserDisconnectEventListener listener)
  • Description

    Add disconnected event listener. When a server closes the connection or the server crashes, the listener's handleDisconnectEvent function will be invoked.

• addDisconnectEventListener(BrowserDisconnectEventListener listener)
  • Description

    Add disconnected event listener. When a server closes the connection or the server crashes, the listener's handleDisconnectEvent function will be invoked.

• addMonitorEventListener(cdevData data, BrowserMonitorEventListener listener)
  • Description

    Add monitor event listener. This is the way to monitor server logging messages. The data argument specify monitor selection message. When a logging message is inserted into the server, the server will send the message to the browser and listener's handleMonitorEvent function is invoked.

• query(cdevData data, BrowserQueryEventListener listener)
  • Description

    Initiate a query. This is the way to query server logged messages. The data argument specify query selection message. When the server find matched messages, these messaged are sent back to the browser and listener's handleQueryEvent function is invoked.

• removeMonitorEventListener(cdevData data, BrowserMonitorEventListener listener)
  • Description

    Stop a monitor process.

• stopQuery(cdevData data, BrowserEvent event)
  • Description

    Stop a query. The event argument is the event returned by query call.
