  command - the command to run the first time the registration is removed, not null

  Returns:

  a registration that will invoke the command once, not null

  registrations - the registrations to remove, not null

  Returns:

  a registration that removes all provided registrations, not null

• addAndRemove

  static <T> Registration addAndRemove(Collection<T> collection, T item)

  Creates a registration by adding an item to a collection immediately and removing the item from the collection when the registration is removed.

  Care should be used when using this pattern to iterate over a copy of the collection to avoid ConcurrentModificationException if a listener or other callback may trigger adding or removing registrations.

  Parameters:

  collection - the collection to which the item should be added and removed, not null

  item - the item to add and remove

  Returns:

  a registration that will remove the item from the collection, not null
