registerUserEventClass

public void registerUserEventClass(Class<? extends ManagerEvent> userEventClass)

Description copied from interface: ManagerConnection

Registers a new user event type.

Asterisk allows you to send custom events via the UserEvent application. If you choose to send such events you can extend the abstract class UserEvent provide a name for your new event and optionally add your own attributes. After registering a user event type Asterisk-Java will handle such events the same way it handles the internal events and inform your registered event handlers.

Note: If you write your own Asterisk applications that use Asterisk's manager_event() function directly and don't use the channel and uniqueid attributes provided by UserEvent you can also register events that directly subclass ManagerEvent.

The event class must be a concrete class with a default constructor (one that takes no arguments).

Specified by:

registerUserEventClass in interface ManagerConnection

Parameters:

userEventClass - the class representing the user event to register.

See Also:

UserEvent, ManagerEvent

setSocketTimeout

Description copied from interface: ManagerConnection

The timeout to use when connecting the the Asterisk server.

Default is 0, that is using Java's built-in default.

Specified by:

setSocketTimeout in interface ManagerConnection

Parameters:

socketTimeout - the timeout value to be used in milliseconds.

See Also:

Socket.connect(java.net.SocketAddress, int)

setSocketReadTimeout

public void setSocketReadTimeout(int socketReadTimeout)

Description copied from interface: ManagerConnection

Connection is dropped (and restarted) if it stales on read longer than the timeout.

If you set this property to a non zero value be sure to also use a PingThread or somthing similar to make sure there is some network traffic, otherwise you will encounter lots of unexpected reconnects. The read timeout should be at least twice the interval set for the PingThread.

Default is 0, that is no read timeout.

Specified by:

setSocketReadTimeout in interface ManagerConnection

Parameters:

socketReadTimeout - the read timeout value to be used in milliseconds.
