Public Methods
Method		Defined By
	new Roo.data.SimpleStore (Object *config) Create a new Roo.data.SimpleStore Create a new Roo.data.SimpleStore Parameters: Object config*
	add (Roo.data.Record[] *records) Add Records to the Store and fires the add event. Add Records to the Store and fires the add event. Parameters: Roo.data.Record[] records* An Array of Roo.data.Record objects to add to the cache.	Roo.data.Store
	addEvents (Object *object) Used to define events on this Observable Used to define events on this Observable Parameters: Object object* The object with the events defined	Roo.util.Observable
	addListener (String *eventName, Function handler, Object scope, Object options) Appends an event handler to this component Appends an event handler to this component Parameters: String eventName* The type of event to listen for Function handler The method the event invokes Object scope (optional) The scope in which to execute the handler function. The handler function's "this" context. Object options (optional) An object containing handler configuration properties. This may contain any of the following properties: scope {Object} The scope in which to execute the handler function. The handler function's "this" context. delay {Number} The number of milliseconds to delay the invocation of the handler after te event fires. single {Boolean} True to add a handler to handle just the next firing of the event, and then remove itself. buffer {Number} Causes the handler to be scheduled to run in an {link Roo.util.DelayedTask} delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place. Combining Options Using the options argument, it is possible to combine different types of listeners: A normalized, delayed, one-time listener that auto stops the event and passes a custom argument (forumId) `el.on('click', this.onClick, this, { single: true, delay: 100, forumId: 4 });` Attaching multiple handlers in 1 call The method also allows for a single argument to be passed which is a config object containing properties which specify multiple handlers. `el.on({ 'click': { fn: this.onClick, scope: this, delay: 100 }, 'mouseover': { fn: this.onMouseOver, scope: this }, 'mouseout': { fn: this.onMouseOut, scope: this } });` Or a shorthand syntax which passes the same scope object to all handlers: `el.on({ 'click': this.onClick, 'mouseover': this.onMouseOver, 'mouseout': this.onMouseOut, scope: this });`	Roo.util.Observable
