  • Create a callback list using the following parameters:

  • options: an optional list of space-separated options that will change how

  • "fired" multiple times.
    *
  • Possible options:
    *
  • once: will ensure the callback list can only be fired once (like a Deferred)
    *
  • memory: will keep track of previous values and will call any callback added
  • after the list has been fired right away with the latest "memorized"
  • values (like a Deferred)
    *
  • unique: will ensure a callback can only be added once (no duplicate in the list)
    *
  • stopOnFalse: interrupt callings when a callback returns false

// 1. Enforce API surface and semantic compatibility with 1.9.x branch
// 2. Improve the module's maintainability by reducing the storage
// paths to a single mechanism.
// 3. Use the same single mechanism to support "private" and "user" data.
// 4. Never expose "private" data to user code (TODO: Drop _data, _removeData)
// 5. Avoid exposing implementation details on user objects (eg. expando properties)
// 6. Provide a clear path for implementation upgrade to WeakMap in 2014
