Hi All, I'm trying to understand the generated model class in SAP Hybris 6.2, this example is from from ProductModel class. Trying to understand this e.g. setter method, can anyone pls help in understanding the below questions?

• getPersistenceContext() //not sure where this method is coming from in this class, it appears to be repeated in every setter?
• setPropertyValue(); //is this a hibernate method, don't see any package imported in the class?
• @Accessor(qualifier = "priceQuantity", type = Accessor.Type.SETTER) //what this annotation means?

Answer 1

• AbstractItemModel(ProductModel's super class) has getPersistenceContext() this method which returns its local variable ItemModelInternalContext
  • ItemModelInternalContext is interface which has method signature getPropertyValue() its implementation is in ItemModelContextImpl
  • Accessor explanation is here https://projectlombok.org/features/experimental/Accessors
