Class Ext.StoreMgr

The key to associate with the item, or the new item.

If a getKey implementation was specified for this MixedCollection, or if the key of the stored items is in a property called id, the MixedCollection will be able to derive the key for the new item. In this case just pass the new item in this parameter.

this.addEvents('storeloaded', 'storecleared');

• scope : Object
  The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.
• delay : Number
  The number of milliseconds to delay the invocation of the handler after the 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 Ext.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.
• target : Observable
  Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

Combining Options
Using the options argument, it is possible to combine different types of listeners:

A delayed, one-time listener.

myDataView.on('click', this.onClick, this, {
single: true,
delay: 100
});

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.

myGridPanel.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:

myGridPanel.on({
'click' : this.onClick,
'mouseover' : this.onMouseOver,
'mouseout' : this.onMouseOut,
 scope: this
});

The key associated with the item to replace, or the replacement item.

If you supplied a getKey implementation for this MixedCollection, or if the key of your stored items is in a property called id, then the MixedCollection will be able to derive the key of the replacement item. If you want to replace an item with one having the same key value, then just pass the replacement item in this parameter.
