public class EApplet

extends Applet

The class also provides access to some important Jive classes.

All classes subclassing EApplet must first call super.init() in their init method. This will initializ the Jive client.

class Example extends EApplet {
    public void init() {
       super.init();
    }
} 

The HTML code must also contain a PARAM tag specifying which port to use on the server.

connect()

This method connect the Applet to the Erlang Jive server.

connected()

This method checks whether the Applet is connected to the Erlang Jive server or not.

disconnect()

This method disconnect the Applet from the Erlang Jive server.

getESock()

Returns the ESock object used for socket communication with the Erlang Jive server.

init()

This method will initialize the Jive client.

receiver()

Returns the EReceiver object used for registering objects which should be called from Erlang.

self()

Returns the EProcess representing the client's peer Erlang process.

start()

This method will be called everytime the Applet is started.

stop()

This method will be called everytime the Applet is stopped.

  public EApplet()

  public void init()

This method will initialize the Jive client. It must be called by the subclassing Applet's init method.

Overrides:

init in class Applet

  public void start()

This method will be called everytime the Applet is started. It will try to connect the Applet to the Erlang Jive server.

Overrides:

start in class Applet

  public void stop()

This method will be called everytime the Applet is stopped. It will try to disconnect the Applet from the server.

Overrides:

stop in class Applet

  public void connect() throws JiveIOException

This method connect the Applet to the Erlang Jive server. If a connection is already in place nothing happens. If a connection cannot be established a JiveIOException is thrown

Throws: JiveIOException

If a connection error occurred or if the receiver was uninitialized.

  public void disconnect()

This method disconnect the Applet from the Erlang Jive server. If the Applet already is disconnected nothing happens.

  public boolean connected()

This method checks whether the Applet is connected to the Erlang Jive server or not.

  public ESock getESock()

Returns the ESock object used for socket communication with the Erlang Jive server.

  public EReceiver receiver()

Returns the EReceiver object used for registering objects which should be called from Erlang.

  public EProcess self() throws JiveIOException

Returns the EProcess representing the client's peer Erlang process. The peer Erlang process mimics the client in the Erlang system and forward all messages sent to it (and vice versa).

The self process should be supplied to all Erlang processes wanting to send information back to the client.

Throws: JiveIOException

If the client isn't connected.
