Interface TopLinkOperations

All Known Implementing Classes:: TopLinkTemplate

public interface TopLinkOperations

Interface that specifies a basic set of TopLink operations, implemented by TopLinkTemplate. Not often used, but a useful option to enhance testability, as it can easily be mocked or stubbed.

Defines TopLinkTemplate's data access methods that mirror various TopLink Session / UnitOfWork methods. Users are strongly encouraged to read the TopLink javadocs for details on the semantics of those methods.

Since:: 1.2
Author:: Juergen Hoeller

Method Detail

execute

Object execute(TopLinkCallback action)
               throws DataAccessException

Execute the action specified by the given action object within a TopLink Session. Application exceptions thrown by the action object get propagated to the caller (can only be unchecked). TopLink exceptions are transformed into appropriate DAO ones. Allows for returning a result object, i.e. a domain object or a collection of domain objects.

Note: Callback code is not supposed to handle transactions itself! Use an appropriate transaction manager like TopLinkTransactionManager.

Parameters:: action - callback object that specifies the TopLink action
Returns:: a result object returned by the action, or null
Throws:: DataAccessException - in case of TopLink errors
See Also:: TopLinkTransactionManager, org.springframework.dao, org.springframework.transaction, Session

executeFind

Returns:: a Collection result returned by the action, or null
Throws:: DataAccessException - in case of TopLink errors

See Also:: UnitOfWork.mergeClone(Object)

deepMerge

Object deepMerge(Object entity)
