|
*
|
* Contains a collection of all stores that are created that have an identifier. An identifier can be assigned by
|
* setting the {@link Ext.data.AbstractStore#storeId storeId} property. When a store is in the StoreManager, it can be
|
* referred to via it's identifier:
|
*
|
* Ext.create('Ext.data.Store', {
|
* model: 'SomeModel',
|
* storeId: 'myStore'
|
* });
|
*
|
* var store = Ext.data.StoreManager.lookup('myStore');
|
*
|
* Also note that the {@link #lookup} method is aliased to {@link Ext#getStore} for convenience.
|
*
|
* If a store is registered with the StoreManager, you can also refer to the store by it's identifier when registering
|
* it with any Component that consumes data from a store:
|
*
|
* Ext.create('Ext.data.Store', {
|
* model: 'SomeModel',
|
* storeId: 'myStore'
|
* });
|
*
|
* Ext.create('Ext.view.View', {
|
* store: 'myStore',
|
* // other configuration here
|
* });
