Interface ClientProducer

All Superinterfaces:
AutoCloseable

public interface ClientProducer extends AutoCloseable
A ClientProducer is used to send messages to a specific address. Messages are then routed on the server to any queues that are bound to the address. A ClientProducer can either be created with a specific address in mind or with none. With the latter the address must be provided using the appropriate send() method.

The sending semantics can change depending on what blocking semantics are set via ServerLocator.setBlockOnDurableSend(boolean) and ServerLocator.setBlockOnNonDurableSend(boolean) . If set to true then for each message type, durable and non durable respectively, any exceptions such as the address not existing or security exceptions will be thrown at the time of send. Alternatively if set to false then exceptions will only be logged on the server.

The send rate can also be controlled via ServerLocator.setProducerMaxRate(int) and the ServerLocator.setProducerWindowSize(int).

  • Method Details

    • getAddress

      SimpleString getAddress()
      Returns the address where messages will be sent.

      The address can be null if the ClientProducer was creating without specifying an address, that is by using ClientSession.createProducer().
      Returns:
      the address where messages will be sent
    • send

      void send(Message message) throws ActiveMQException
      Sends a message to an address. specified in ClientSession.createProducer(String) or similar methods.

      This will block until confirmation that the message has reached the server has been received if ServerLocator.setBlockOnDurableSend(boolean) or ServerLocator.setBlockOnNonDurableSend(boolean) are set to true for the specified message type.
      Parameters:
      message - the message to send
      Throws:
      ActiveMQException - if an exception occurs while sending the message
    • send

      void send(Message message, SendAcknowledgementHandler handler) throws ActiveMQException
      Sends a message to the specified address instead of the ClientProducer's address.

      This message will be sent asynchronously.

      The handler will only get called if -1.

      Parameters:
      message - the message to send
      handler - handler to call after receiving a SEND acknowledgement from the server
      Throws:
      ActiveMQException - if an exception occurs while sending the message
    • send

      void send(SimpleString address, Message message) throws ActiveMQException
      Sends a message to the specified address instead of the ClientProducer's address.

      This will block until confirmation that the message has reached the server has been received if ServerLocator.setBlockOnDurableSend(boolean) or ServerLocator.setBlockOnNonDurableSend(boolean) are set to true for the specified message type.
      Parameters:
      address - the address where the message will be sent
      message - the message to send
      Throws:
      ActiveMQException - if an exception occurs while sending the message
    • send

      void send(SimpleString address, Message message, SendAcknowledgementHandler handler) throws ActiveMQException
      Sends a message to the specified address instead of the ClientProducer's address.

      This message will be sent asynchronously as long as ServerLocator.setConfirmationWindowSize(int) was set.

      Notice that if no confirmationWindowsize is set

      Parameters:
      address - the address where the message will be sent
      message - the message to send
      handler - handler to call after receiving a SEND acknowledgement from the server
      Throws:
      ActiveMQException - if an exception occurs while sending the message
    • send

      void send(String address, Message message) throws ActiveMQException
      Sends a message to the specified address instead of the ClientProducer's address.

      This will block until confirmation that the message has reached the server has been received if ServerLocator.setBlockOnDurableSend(boolean) or ServerLocator.setBlockOnNonDurableSend(boolean) are set to true for the specified message type.
      Parameters:
      address - the address where the message will be sent
      message - the message to send
      Throws:
      ActiveMQException - if an exception occurs while sending the message
    • close

      void close() throws ActiveMQException

      Specified by:
      close in interface AutoCloseable
