Struct ruex::foundation::patterns::facade::BaseFacade

source · [−]

pub struct BaseFacade<Body> where
    Body: Debug + 'static,  { /* private fields */ }

Expand description

A base Singleton Facade implementation.

In PureMVC, the Facade class assumes these responsibilities:

Initializing the Model, View and Controller Singletons.
Providing all the methods defined by the Model, View, & Controller interfaces.
Providing a single point of contact to the application for registering Command’s and notifying Observer’s

Implementations

source

impl<Body> BaseFacade<Body> where
Body: Debug + 'static,

source

pub fn new() -> Self

Create instance of BaseFacade.

Actually, you have to reimplement the Facade for your purposes with Singleton pattern.

This Facade implementation is keept here in educational purposes only.

source

impl<Body> MediatorRegistry<Body> for BaseFacade<Body> where
Body: Debug + 'static,

source

fn register_mediator<M: Mediator<Body>>(&self, mediator: Rc<M>)

Register an Mediator instance with the View.

source

fn retrieve_mediator<M: Mediator<Body>>(&self) -> Option<Rc<M>>

Retrieve an Mediator instance from the View.

source

fn remove_mediator<M: Mediator<Body>>(&self) -> Option<Rc<M>>

Remove a Mediator instance from the View.

source

fn has_mediator<M: Mediator<Body>>(&self) -> bool

Check if a Mediator is registered or not

source

impl<Body> Model for BaseFacade<Body> where
Body: Debug + 'static,

source

fn has_proxy<P: Proxy>(&self) -> bool

Check if a Proxy is registered

source

fn register_proxy<P: Proxy>(&self, proxy: Rc)

Register an Proxy with the Model by name.

source

fn remove_proxy<P: Proxy>(&self) -> Option<Rc>

Remove an Proxy instance from the Model by name.

source

fn retrieve_proxy<P: Proxy>(&self) -> Option<Rc>

Retrieve a Proxy from the Model by name.

source

impl<Body> Singleton for BaseFacade<Body> where
Body: Debug + 'static,

source

fn global() -> &'static Self

Facade Singleton Factory method

It is not possible to implement Singleton with generics. So you should implement it in your final code only.

Error: use of generic parameter from outer function

source

impl<Body> View<Body> for BaseFacade<Body> where
Body: Debug + 'static,

source

fn notify(&self, note: Rc<dyn Notification<Body>>)

Notify the Observer’s for a particular Notification.

All previously attached Observer’s for this Notification’s list are notified and are passed a reference to the Notification in the order in which they were registered.

NOTE: Use this method only if you are sending custom Notifications. Otherwise use the sendNotification method which does not require you to create the Notification instance.
