Annotation Type StoreReturn

@Documented
 @Retention(value=RUNTIME)
 @Target(value=METHOD)
public @interface StoreReturn

An around annotation for methods which simplifies storing objects in an associated Store Manager.

This annotation will wrap the decorated method to ensure thread isolation.

You can store a Method return statement.

A method such as this:

  @StoreReturn
 protected Customer updateCustomer(String id, CustomerSave customerSave) {
     Customer c = data().getCustomers().get(id);
     if (c != null) {
         c.setFirstName(customerSave.getFirstName());
         c.setLastName(customerSave.getLastName());
         return c;
     }
     return null;
 }
 

Becomes

 protected Customer updateCustomer(String id, CustomerSave customerSave) {
     XThreads.executeSynchronized(() -> {
         Customer c = data().getCustomers().get(id);
         if (c != null) {
             c.setFirstName(customerSave.getFirstName());
             c.setLastName(customerSave.getLastName());
             embeddedStorageManager.store(c);
             return c;
         }
         return null;
     }
 }
