Examples of org.apache.tuscany.das.rdb.DAS.applyChanges()

org.apache.tuscany.das.rdb.DAS.applyChanges()
The change history is scanned and modifications to the graph of data objects are flushed to the database. @param root the topmost containing data object

        DataObject newCustomer = root.createDataObject("CUSTOMER");
        newCustomer.set("LASTNAME", "NewCustomer");
        newCustomer.setInt("ID", 9000);


        // Build apply changes command
        das.applyChanges(root);


        // Verify the change
        root = select.executeQuery();
        assertEquals("Pavick", getCustomerByLastName(root, "Pavick").getString("LASTNAME"));
        assertEquals("NewCustomer", getCustomerByLastName(root, "NewCustomer").getString("LASTNAME"));
