    • allowsChanges

      public boolean allowsChanges()
      Description copied from class: NodeFeature
      Returns true if the underlying node may report its changes.

      If its return value is false then this node should be considered as "inactive" and should not send any changes to the client side at all or only changes for features that disallow the changes.

      Normally features don't control the node behavior so the default implementation returns true. The feature which wants to control the node behavior should override this method.

      Overrides:
      allowsChanges in class NodeFeature
      Returns:
      true if the feature allows changes for the node, false otherwise
