摘要: A system and method are described for performing a mapping between persistent data objects and a database. For example, a method according to one embodiment of the invention comprises determining whether an attribute having a generic type is an instance of a persistent class; and if the attribute is an instance of a persistent class, then mapping the attribute to a discriminator column holding the type associated with the attribute and further mapping the attribute to a reference column holding a key associated with the attribute.

摘要: Logically locking in a Java Data Object rather than in a transactional context of a data store to separate the process of isolating an object from accessing a data store to which the object is mapped.
摘要翻译: 逻辑上锁定Java数据对象,而不是在数据存储的事务上下文中,将隔离对象的过程与访问对象映射到的数据存储区进行隔离。
