All Implemented Interfaces:

ProductRetrieveStrategy, RefreshableCachedProductRetrieveStrategy, EpService

public class RefreshableCachedProductRetrieveStrategyImpl
extends SingleCachingProductRetrieveStrategyImpl
implements RefreshableCachedProductRetrieveStrategy

Provides an implementation of ProductRetrieveStrategy with JBoss tree caching ability. This service will return the same instance of a product for all customers. Catalog promotion rules have already been applied on the returned products.

Notice: since the Product is not thread-safe, you must not make any changes on the return product in your code. Otherwise, the application may have some unexpected problem. Clients may optionally call refreshCacheEntry(..) to refresh the entry for a product from disk. To use this feature, you must specify a default product load tuner.
