start

public void start()
           throws IOException

Description copied from interface: Messenger

Transitions the Messenger to an active state. A Messenger is initially created in an inactive state. When inactive, a Messenger will not send or receive messages from its internal queues. A Messenger must be started before calling send() or recv().

Specified by:

start in interface Messenger

Throws:

IOException

stop

public void stop()

Description copied from interface: Messenger

Transitions the Messenger to an inactive state. An inactive Messenger will not send or receive messages from its internal queues. A Messenger should be stopped before being discarded to ensure a clean shutdown handshake occurs on any internally managed connections.

Specified by:

public boolean stopped()

Specified by:

work

public boolean work(long timeout)
             throws TimeoutException

Description copied from interface: Messenger

Sends or receives any outstanding messages queued for a messenger. If timeout is zero, no blocking is done. A timeout of -1 blocks forever, otherwise timeout is the maximum time (in millisecs) to block. Returns True if work was performed.

Specified by:

work in interface Messenger

Throws:

TimeoutException

interrupt

public void interrupt()

Specified by:

interrupt in interface Messenger

put

public void put(Message m)
         throws MessengerException

Description copied from interface: Messenger

Specified by:

put in interface Messenger

Throws:

MessengerException

send

public void send()
          throws TimeoutException

Description copied from interface: Messenger

Blocks until the outgoing queue is empty and, in the event that an outgoing window has been set, until the messages in that window have been received by the target to which they were sent, or the operation times out. The timeout property controls how long a Messenger will block before timing out.

Specified by:

send in interface Messenger

Throws:

TimeoutException

send

public void send(int n)
          throws TimeoutException

Specified by:

send in interface Messenger

Throws:

TimeoutException

recv

public void recv(int n)
          throws TimeoutException

Description copied from interface: Messenger

Receives up to the specified number of messages into the incoming queue of the Messenger. This method will block until at least one message is available or the operation times out.

Specified by:

recv in interface Messenger

Throws:

TimeoutException

recv

public void recv()
          throws TimeoutException

Description copied from interface: Messenger

Subscribes the Messenger to messages originating from the specified source. The source is an address as specified in the Messenger introduction with the following addition. If the domain portion of the address begins with the '~' character, the Messenger will interpret the domain as host/port, bind to it, and listen for incoming messages. For example "~0.0.0.0", "amqp://~0.0.0.0" will bind to any local interface and listen for incoming messages.

Specified by:

subscribe in interface Messenger
