/**
*
* 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:
*
* {@literal @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;
* });
* }
*
*
* @see EclipseStore mutable data docs.
