    • setObserversActive

      void setObserversActive​(boolean isActive)

      Parameters:
      isActive - When true then Request-Correlation is enabled, else disabled.

    • withEnableObservers

      B withEnableObservers()
      Builder method for the enableObservers() operation.

    • disableObservers

      default void disableObservers()
      Disables all observables.

    • isObserversActive

      boolean isObserversActive()
      Returns true when all Observer instances are theoretically active (the instance may also decide by itself), else false.

    • withDisableObservers

      B withDisableObservers()
      Builder method for the disableObservers() operation.
      Returns:
      The builder for applying multiple build operations.
