Registers a listener for updates from the model.
Registers a listener for updates from the model.
A listener is simply a partial function which receives instances of U. Therefore
the listener can decide with pattern match cases which updates it wants to handle.
Example:
m.addListener {
case NcviewSync.Open(path) => ...
}Note: If the listener should be removed at some point, it is important to store it somewhere:
val l: NcviewSync.Listener = { case NcviewSync.Open(path) => ... } m.addListener(l) ... m.removeListener(l)
Synchronously dispatches an update to all currently registered listeners.
Synchronously dispatches an update to all currently registered listeners. Non fatal exceptions are caught on a per-listener basis without stopping the dispatch.
Removes all listeners.
Removes all listeners. This is useful when disposing the model, to remove any unnecessary references.
Unregisters a listener for updates from the model.
A straight forward implementation of a model. The trait implements all required methods and provides a
dispatchmethod to fire any updates.
