      public BooleanArraySubscriber subscribe​(boolean[] defaultValue, PubSubOption... options)
      Create a new subscriber to the topic.

      The subscriber is only active as long as the returned object is not closed.

      Subscribers that do not match the published data type do not return any values. To determine if the data type matches, use the appropriate Topic functions.

      Parameters:
      defaultValue - default value used when a default is not provided to a getter function
      options - subscribe options
      Returns:
      subscriber
    • subscribeEx

      public BooleanArraySubscriber subscribeEx​(String typeString, boolean[] defaultValue, PubSubOption... options)
      Create a new subscriber to the topic, with specified type string.

      The subscriber is only active as long as the returned object is not closed.

      The publisher is only active as long as the returned object is not closed.

      It is not possible to publish two different data types to the same topic. Conflicts between publishers are typically resolved by the server on a first-come, first-served basis. Any published values that do not match the topic's data type are dropped (ignored). To determine if the data type matches, use the appropriate Topic functions.

      Parameters:
