Annotation Interface StoreParams

@Documented @Retention(RUNTIME) @Target(METHOD) public @interface StoreParams
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 method parameters.

A method such as this: 

 @Store(parameters = "customers")
 protected Customer addCustomer(Map<String, Customer> customers, CustomerSave customerSave) {
     String id = UUID.randomUUID().toString();
     Customer customer = new Customer(id, customerSave.getFirstName(), customerSave.getLastName());
     customers.put(id, customer);
     return customer;
 }

Becomes 

 protected Customer addCustomer(Map<String, Customer> customers, CustomerSave customerSave) {
     return XThreads.executeSynchronized(() -> {
         String id = UUID.randomUUID().toString();
         Customer customer = new Customer(id, customerSave.getFirstName(), customerSave.getLastName());
         customers.put(id, customer);
         embeddedStorageManager.store(customers);
         return customer;
     });
 }
