This is a very long pattern. To implement and facilitate this implementation, we will save all the data on HashMap. This is an important step, because the focus of this subsection is to demonstrate how to implement domain-store patterns. To facilitate our understanding, we will look at the same scenario covered in the Implementing the data-access object pattern subsection. Here, we have the transfer object, called Employee, and we will also read and write data on the data source. However, persistence will be oriented by object state and will have an intelligence in its logic.. In this implementation, we have the following classes, interfaces, and annotations:
- PersistenceManagerFactory: This works as a factory pattern and is responsible for creating instances of the PersistenceManager class. PersistenceManagerFactory is...
