		String	topic
	)		throws UMDSException

Member Function Documentation

final void com.latencybusters.umds.UMDSReceiver.close ( ) throws UMDSException

inherited

Close this receiver. The server will send an asynchronous ACK for this operation, queued messages will be received before the ACK is delivered.

Exceptions

UMDSException When the receiver could not be cleanly deleted

void com.latencybusters.umds.UMDSReceiverBase.log	(	int	level,
		String	comment
	)

inherited

Log a receiver related message. This API currently does nothing unique, but is provided as an aid to users deriving from the class but may in the future be updated to identify the receiver automatically.

Exceptions

UMDSException the UMDS exception

void com.latencybusters.umds.UMDSReceiver.onEvent ( UMDSMessage msg )

inherited

Event Notification function. This function is called when non-data events occur, E.G. Loss reported by the server.

This should be overridden by applications.

Expected message types: LOSS, DISCONNECT, SERVER_DENIED, RECEIVER_CREATE and RECEIVER_DELETE.

Parameters

msg	The message containing the event

void com.latencybusters.umds.UMDSReceiver.onMessage ( UMDSMessage msg )

inherited

Message Delivery function. This is called to deliver messages to the application.

This should be overridden by applications.

Only data messages will be given to onMessage()

See also: onEvent

Parameters

msg	The message containing the received data

void com.latencybusters.umds.UMDSReceiver.onRequest ( UMDSMessage msg )

inherited

Callback for request messages received. Implement this method to receive requests. Expected message types: REQUEST.

Parameters

msg	The type for request messages is REQUEST. All UMDSMessage interfaces that are valid for DATA messages are also valid for request messages. The requestID is undefined for received requests, as it is a source-side-only correlation ID.
