      public ReactiveAdapterRegistry getAdapterRegistry()
      Return the configured ReactiveAdapterRegistry.

    • setOrder

      public void setOrder(int order)
      Set the order for this result handler relative to others.

      By default set to Ordered.LOWEST_PRECEDENCE, however see Javadoc of sub-classes which may change this default.

      Parameters:
      order - the order

    • getOrder

      public int getOrder()
      Description copied from interface: Ordered
      Get the order value of this object.

      Higher values are interpreted as lower priority. As a consequence, the object with the lowest value has the highest priority (somewhat analogous to Servlet load-on-startup values).

      Same order values will result in arbitrary sort positions for the affected objects.

      Specified by:
      getOrder in interface Ordered
      Returns:
      the order value
