Class AbstractContentDataDAOImpl

  • All Implemented Interfaces:
    ContentDataDAO
    Direct Known Subclasses:
    ContentDataDAOImpl
    public abstract class AbstractContentDataDAOImpl
extends java.lang.Object
implements ContentDataDAO
    Abstract implementation for ContentData DAO.

    This provides basic services such as caching, but defers to the underlying implementation for CRUD operations.

    The DAO deals in ContentData instances. The cache is primarily present to decode IDs into ContentData instances.
