dashboardMirror.js
¶

This module provides a mirror of the dashboard model that updates state based on processing configuration change actions.

Curran Kelleher 3/30/2014
```
define([], function () {
  return function DashboardMirror(){
```
¶

Keeps track of the entire dashboard model as a simple JavaScript object.
- Keys are component aliases
- Values are component option objects
```
    components = {};

    return {
```
¶

Gets a component options object for the given alias.
```
      get: function (alias) {
```

Protect from outside mutation by cloning

        return _.clone(components[alias]);
      },
      update: function (change){

change.deletedComponents.forEach(function (alias) { // TODO test this codepath delete existingComponents[alias]; });

        change.createdComponents.forEach(function (component) {
          components[component.alias] = { module: component.module };
        });
        change.updatedComponents.forEach(function (component) {
          _.extend(components[component.alias], component.options);
        });
      }
    }
  };
});
