App.ObjectStore

The App.ObjectStore is responsible for all current state on the client. When the state of the store changes events are triggered based on what caused the change. All changes of the state should go through an method in the App.ObjectAction module to make sure listening components get notified of the state change.

There are 3 different type of events that can be listened for

change is triggered when an object is edited
created is triggered when an object is created
received is triggered when an object is received from the server

Example of listening to events

Example

// Object that has been changed
App.ObjectStore.addChangeEventListener(function(changedObjects) {
   App.log.debug("Objects where changed", changedObjects);
});

// Object that has been created
App.ObjectStore.addCreatedEventListener(function(createdObjects) {
   App.log.debug("Objects where created", createdObjectes);
});

// Object that has been received from the server
App.ObjectStore.addReceivedListener(function(receivedObjects) {
   App.log.debug("Objects where received from the server", receivedObjects);
});

Methods

(static) addChangeListener(callback, listenerId, filterList)

Adds an change listener that will be notified when an change event is triggered.

Parameters:

Name	Type	Description

`filterList`	Array	ids of listeners that should be notified. (optional)

(static) addCreateListener(callback, listenerId, filterList)

Adds an create listener that will be notified when an create event is triggered.

Parameters:

Name	Type	Description

`listenerId`	String	id. Will not be notified of change of its own events. (optional)
`filterList`	Array	ids of listeners that should be notified. (optional)

(static) addReceivedListener(callback, listenerId, filterList)

Adds an receive listener that will be notified when an receive event is triggered.

Parameters:

Name	Type	Description

Returns the number of objects currently in the store

Returns:

Type: Integer

(static) emitChange(objects, emitter)

Emits an change event, that will notify listening components

Warning: This should be triggered by the App.Dispatcher, there should be no need to call this method directly

Parameters:

Name	Type	Description

`emitter`	String	id of origin of event. Will not be notified of change if: listener is the emitter or if emitter was not on the filterList.

(static) emitReceive(objects, emitter)

Emits an receive event, i.e. when data is returned from the server, that will notify listening components Warning: This should be triggered by the App.Dispatcher, there should be no need to call this method directly

Parameters:

Name	Type	Description
`objects`	Object	that have been received
`emitter`	String	id of origin of event. Will not be notified of change if: listener is the emitter or if emitter was not on the filterList.
