Ext.data.Store's each() is ignoring filtered records

I am using Ext.data.Store's each(). But this method, when store is filtered, only loops over the filtered records. Do we have any other method or work around to loop over all the records of a store even when a filter is applied on the store.

  var attStore = Ext.getStore("myStore");
        var allRecords = attStore.snapshot || attStore.data;
        allRecords.each(function (record) {
            if (record.data.IsUpdated) {
                record.set('updatedByUser', true);
            }
            else {
                record.set('updatedByUser', false);
            }
             record.commit();
        });

The line var allRecords = attStore.snapshot || attStore.data;actually returns all the records as intended but when I try to update that record (or one of the property in that record using record.data.property = something) That record is not getting updated.

Thanks

use this

var allRecords = store.snapshot || store.data;

and loop like this

allRecords.each(function(record) {
    console.log(record);
});

see this store snapshot
