// Sammy.Store is an abstract adapter class that wraps the multitude of in
|
|
// browser data storage into a single common set of methods for storing and
|
|
// retreiving data. The JSON library is used (through the inclusion of the
|
|
// Sammy.JSON) plugin, to automatically convert objects back and forth from
|
|
// stored strings.
|
|
//
|
|
// Sammy.Store can be used directly, but within a Sammy.Application it is much
|
|
// easier to use the `Sammy.Storage` plugin and its helper methods.
|
|
//
|
|
// Sammy.Store also supports the KVO pattern, by firing DOM/jQuery Events when
|
|
// a key is set.
|
|
//
|
|
// ### Example
|
|
//
|
|
// // create a new store named 'mystore', tied to the #main element, using HTML5 localStorage
|
|
// // Note: localStorage only works on browsers that support it
|
|
// var store = new Sammy.Store({name: 'mystore', element: '#element', type: 'local'});
|
|
// store.set('foo', 'bar');
|
|
// store.get('foo'); //=> 'bar'
|
|
// store.set('json', {obj: 'this is an obj'});
|
|
// store.get('json'); //=> {obj: 'this is an obj'}
|
|
// store.keys(); //=> ['foo','json']
|
|
// store.clear('foo');
|
|
// store.keys(); //=> ['json']
|
|
// store.clearAll();
|
|
// store.keys(); //=> []
|
|
//
|
|
// ### Arguments
|
|
//
|
|
// The constructor takes a single argument which is a Object containing these possible options.
|
|
//
|
|
// * `name` The name/namespace of this store. Stores are unique by name/type. (default 'store')
|
|
// * `element` A selector for the element that the store is bound to. (default 'body')
|
|
// * `type` The type of storage/proxy to use (default 'memory')
|
|
//
|
|
// Extra options are passed to the storage constructor.
|
|
// Sammy.Store supports the following methods of storage:
|
|
//
|
|
// * `memory` Basic object storage
|
|
// * `data` jQuery.data DOM Storage
|
|
// * `cookie` Access to document.cookie. Limited to 2K
|
|
// * `local` HTML5 DOM localStorage, browswer support is currently limited.
|
|
// * `session` HTML5 DOM sessionStorage, browswer support is currently limited.
|
|
//

|
// possible storage type for the session. This means, `LocalStorage`
|
|
// if available, otherwise `Cookie`, otherwise `Memory`.
|

// It provides the `session()` helper through `Sammy.Storage#store()`.

// you dont have to worry about collisions. As of 0.5 the original Sammy.Cache module

// has been deprecated in favor of this one based on Sammy.Storage. The exposed
|
|
// API is almost identical, but Sammy.Storage provides additional backends including
|

// HTML5 Storage. `Sammy.Cache` will try to use these backends when available
|
|
// (in this order) `LocalStorage`, `SessionStorage`, and `Memory`
