Sencha Touch 2: How to get (multiple) instances of a base class

Question

I got the following classes on a Sencha Web App:

Baseclass

and AClass extends Baseclass with xtype aclass

and BClass extends Baseclass with xtype bclass

Usually I usually would use Ext.Viewport.down('aclass') to get a certain instance of a class. My question is if there's a way to get all instances of the Baseclass?

Thanks for help!

Answer 1

Ext.define('BaseClass', {
    extend: 'Ext.Component',
    xtype: 'baseclass'
});

Ext.define('AClass', {
    extend: 'BaseClass',
    xtype: 'aclass'
});

Ext.define('BClass', {
    extend: 'BaseClass',
    xtype: 'bclass'
});

var instances = Ext.ComponentQuery.query('baseclass') 

will return array with all instances of AClass and BClass
