      public void setQueueSize(int size)
      Sets the default maximum capacity of the SEDA queue (i.e., the number of messages it can hold).

    • setConcurrentConsumers

      public void setConcurrentConsumers(int size)
      Sets the default number of concurrent threads processing exchanges.

      Sets the default queue factory.

    • isDefaultBlockWhenFull

      public boolean isDefaultBlockWhenFull()

    • setDefaultBlockWhenFull

      public void setDefaultBlockWhenFull(boolean defaultBlockWhenFull)
      Whether a thread that sends messages to a full SEDA queue will block until the queue's capacity is no longer exhausted. By default, an exception will be thrown stating that the queue is full. By enabling this option, the calling thread will instead block and wait until the message can be accepted.

    • isDefaultDiscardWhenFull

      public boolean isDefaultDiscardWhenFull()
      Whether a thread that sends messages to a full SEDA queue will be discarded. By default, an exception will be thrown stating that the queue is full. By enabling this option, the calling thread will give up sending and continue, meaning that the message was not sent to the SEDA queue.

    • setDefaultDiscardWhenFull

      public void setDefaultDiscardWhenFull(boolean defaultDiscardWhenFull)

    • getDefaultOfferTimeout

      public long getDefaultOfferTimeout()

    • setDefaultOfferTimeout

      public void setDefaultOfferTimeout(long defaultOfferTimeout)
      Whether a thread that sends messages to a full SEDA queue will block until the queue's capacity is no longer exhausted. By default, an exception will be thrown stating that the queue is full. By enabling this option, where a configured timeout can be added to the block case. Utilizing the .offer(timeout) method of the underlining java queue

    • getDefaultPollTimeout

      public int getDefaultPollTimeout()

    • setDefaultPollTimeout

      public void setDefaultPollTimeout(int defaultPollTimeout)
      The timeout (in milliseconds) used when polling. When a timeout occurs, the consumer can check whether it is allowed to continue running. Setting a lower value allows the consumer to react more quickly upon shutdown.
