/**
+ * @class Ext.data.StoreManager
+ * @extends Ext.util.MixedCollection
+ * <p>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:
+ * <pre><code>
+Ext.create('Ext.data.Store', {
+ model: 'SomeModel',
+ storeId: 'myStore'
+});
+
+var store = Ext.data.StoreManager.lookup('myStore');
+ * </code></pre>
+ * Also note that the {@link #lookup} method is aliased to {@link Ext#getStore} for convenience.</p>
+ * <p>
+ * 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:
+ * <pre><code>
+Ext.create('Ext.data.Store', {
+ model: 'SomeModel',
+ storeId: 'myStore'
+});
+
+Ext.create('Ext.view.View', {
+ store: 'myStore',
+ // other configuration here
+});
+ * </code></pre>
