|
value, key: value})
|
|
@param fields: (optional) list of field hashes (each hash defining a hash
|

as per recline.Model.Field). If fields not specified they will be taken

<h2>Memory Backend - uses in-memory data</h2>
|
|
<p>To use it you should provide in your constructor data:</p>
|
|
<ul>
|
|
<li>metadata (including fields array)</li>
|
|
<li>documents: list of hashes, each hash being one doc. A doc <em>must</em> have an id attribute which is unique.</li>
|
|
</ul>
|
|
<p>Example:</p>
|
|
<p><pre>
|
|
// Backend setup
|
|
var backend = recline.Backend.Memory();
|
|
backend.addDataset({
|
|
metadata: {
|
|
id: 'my-id',
|
|
title: 'My Title'
|
|
},
|
|
fields: [{id: 'x'}, {id: 'y'}, {id: 'z'}],
|
|
documents: [
|
|
{id: 0, x: 1, y: 2, z: 3},
|
|
{id: 1, x: 2, y: 4, z: 6}
|
|
]
|
|
});
|
|
// later ...
|
|
var dataset = Dataset({id: 'my-id'}, 'memory');
|
|
dataset.fetch();
|
|
etc ...
