code: public static Manager manager(
              ComponentType component, Channel componentChannel) {
          return ComponentVertex.componentVertex(component, componentChannel);
      }
docs: Returns a component's manager like {@link #manager(ComponentType)}.
  If the manager slot attribute is empty, the component is initialized
  with its component channel set to the given parameter. Invoking
  this method overrides any channel set in the
  {@link ComponentManager} annotation.
  
  This method is usually invoked by the constructor of a class
  that implements {@link ComponentType}.
  
  @param component the component
  @param componentChannel the channel that the component's
  handlers listen on by default and that
  {@link Manager#fire(Event, Channel...)} sends the event to
  @return the component (with its manager attribute set)
  @see Component#Component(Channel)
