An Ember Object Proxy (and mixin) that enables change buffering. Ever need to "hold back" property changes before they propagate? If so, this may be the addon for you.

## Usage

```sh

ember install ember-buffered-proxy

```

```js

import BufferedProxy from 'ember-buffered-proxy/proxy';

let content = {

  firstName: 'stefan'

};

let buffer = BufferedProxy.create({

  content: content

});

buffer.get('firstName'); // => 'stefan'

buffer.set('firstName', 'Kris');

buffer.get('firstName'); // => 'Kris'

buffer.get('content.firstName'); // => 'stefan'

buffer.get('hasChanges'); // => true

buffer.buffer; // => (get an object describing changed keys) -- {"firstName": "Kris"}

buffer.applyBufferedChanges();

buffer.get('firstName'); // => 'Kris'

buffer.get('content.firstName'); // => 'Kris'

buffer.get('hasChanges'); // => false

buffer.set('firstName', 'Luke');

buffer.get('firstName'); // => 'Luke'

buffer.get('content.firstName'); // => 'Kris'

buffer.hasChanged('firstName'); // => true

buffer.discardBufferedChanges();

buffer.get('firstName'); // => 'Kris'

buffer.get('content.firstName'); // => 'Kris'

buffer.hasChanged('firstName'); // => false

// Below demonstrates that applyBufferedChanges and discardBufferedChanges

// can take an optional array of keys.

buffer.set('email', '[email protected]');

buffer.get('email'); // => '[email protected]'

buffer.get('content.email'); // => undefined

buffer.set('address', '123 paradise road');

buffer.get('address'); // => '123 paradise road'

buffer.get('content.address'); // => undefined

buffer.applyBufferedChanges(['email']); // Only apply the email from the buffer

buffer.get('email'); // => '[email protected]'

buffer.get('address'); // => '123 paradise road'

buffer.get('content.email'); // => '[email protected]'

buffer.get('content.address'); // => undefined

buffer.setProperties({

  email: '[email protected]',

  address: '1717 rose street'

});

buffer.discardBufferedChanges(['address']); // Discard only the address property from the buffer

buffer.get('email'); // => [email protected]

buffer.get('address'); // => undefined

```

You can also use these shorter method names

```js

buffer.discardChanges(); // equivalent to buffer.discardBufferedChanges()

buffer.applyChanges();   // equivalent to buffer.applyBufferedChanges()

```

Or you can grab the mixin directly

```js

import BufferedMixin from 'ember-buffered-proxy/mixin';

let content = {

  firstName: 'stefan'

};

let buffer = ObjectProxy.extend(BufferedMixin).create({

  content: content

});

// same as above

```
