      Modifier and Type Method Description
      void close()
      Closes down this service factory and releases all underlying resources.
      int getQosMetricBufferSizePerConsumer()
      Returns an indication of the size of each consumer's notification buffer (for service implementations which provide buffering).
      boolean getQosMetricIsBuffered()
      Returns an indication of whether this service implementation can be expected to drop notifications or whether it will buffer them in situations where the publication rate exceeds the rate at which the consumers can process the data.
      boolean getQosMetricIsNullPublishable()
      Returns an indication of whether the publish method accepts null as a valid token to be sent to the Coinsumer.
      int getQosMetricNumberOfNotificationThreadsPerConsumer()
      Returns an indication of how many threads the consumer may be called back on.
      int getServiceCount()
      Returns the count of service instances created by this provider.
      <T> MonitorNotificationService<T> getServiceForConsumer​(java.util.function.Consumer<? super T> consumer)
      Returns a service instance which will publish events to the specified Consumer.

    • Method Detail

      • getServiceForConsumer

        <T> MonitorNotificationService<T> getServiceForConsumer​(java.util.function.Consumer<? super T> consumer)
        Returns a service instance which will publish events to the specified Consumer.
        Type Parameters:
        T - the type of events that this service instance will publish.
        Parameters:
        consumer - the consumer to publish to.
        Returns:
        the service instance.

      • close

        void close()
        Closes down this service factory and releases all underlying resources.
        Specified by:
        close in interface java.lang.AutoCloseable

      • getServiceCount

        int getServiceCount()
        Returns the count of service instances created by this provider.
        Returns:
        the result.

      • getQosMetricIsBuffered

        boolean getQosMetricIsBuffered()
        Returns an indication of whether this service implementation can be expected to drop notifications or whether it will buffer them in situations where the publication rate exceeds the rate at which the consumers can process the data.
        Returns:
        the result.

      • getQosMetricBufferSizePerConsumer

        int getQosMetricBufferSizePerConsumer()
        Returns an indication of the size of each consumer's notification buffer (for service implementations which provide buffering). Returns 1 in the case that the service implementation is not buffered.
        Returns:
        the result.

      • getQosMetricNumberOfNotificationThreadsPerConsumer

        int getQosMetricNumberOfNotificationThreadsPerConsumer()
        Returns an indication of how many threads the consumer may be called back on. Where multiple threads are involved the consumer may wish to synchronize their accept method to force serialisation of the notification sequence so that events get notified in the same sequence as they were published.
        Returns:
        the result.

      • getQosMetricIsNullPublishable

        boolean getQosMetricIsNullPublishable()
        Returns an indication of whether the publish method accepts null as a valid token to be sent to the Coinsumer.
        Returns:
        the result.
