notifyDependents method

@protected void notifyDependents()

Notifies all dependents and listeners that this node changed.

Implementation

@protected

  // We must snapshot because dependents may re-register during notification
  // (computed nodes clear and re-track their dependencies).

  // Listeners that remove themselves during callback are handled safely
  // via snapshot if the list was modified during iteration.
