Constructor Detail

RepositoryFactory

public RepositoryFactory(HibernateConversationFactory factory)

Constructs a new mFactory that will always use the given conversation locator

Parameters:

factory - a ConversationFactory instance

Method Detail

createDefault

public static RepositoryFactory createDefault()

Creates a new mFactory using a transactional hibernate locator

Returns:

a new mFactory instance

open

public Repository open()

Creates a new repository instance. This implementation creates a new Crud and enhances the repository implementor to use a wrapping interceptor.

Returns:

a new proxy to the Repository

getCallbacks(Crud, ProxyWrapper), getCallbackFilter(Crud), getInterfaces(Crud), getFactory()

getRepositoryImplementorClass

protected Class<? extends RepositoryImplementor> getRepositoryImplementorClass()

Returns the class that implements the repository. The current implementation returns RepositoryImpl.

Returns:

the class that is used to instantiate new repositories

newCrud

protected Crud newCrud()

Creates a new Crud instance, using this mFactory's ConversationLocator. This implementation uses a TransactionalHibernateCrud.

Returns:

a newly instantiated Crud implementation

getCallbackFilter

protected CallbackFilter getCallbackFilter(Crud crud)

Gets the CallbackFilter used to create the Repository proxy.

Parameters:

crud - The Crud instance to be used by the repository

Returns:

this implementation always returns null. Subclasses are allowed to override this, provided that they also override the callbacks

getCallbacks(Crud, ProxyWrapper), open()

getCallbacks

protected Callback[] getCallbacks(Crud crud,
                                  ProxyWrapper pw)

Gets the Callbacks used to used to create the Repository proxy. This implementation always returns a single-element array with a WrappingInterceptor

Parameters:

crud - The Crud instance to be used by the repository

pw - TODO

Returns:

an array of Callback implementations

DispatchingInterceptor, open()

createPersistentWrapper

protected ProxyWrapper createPersistentWrapper(Crud crud)

Creates a ProxyWrapper for persistent instances that uses the given Crud instance.

Parameters:

crud - a crud created by this repository factory

Returns:

a new ProxyWrapper

getFactory

public ConversationFactory getFactory()

Gets the ConversationLocator instance used by this mFactory.

Returns:

the locator instance

getInterfaces

protected Class[] getInterfaces(Crud crud)

Gets all the interfaces to be implemented by the Repository proxy. The current implementation returns a single-element array with the Repository interface

Parameters:

crud - The Crud instance to be used by the repository

Returns:

an array of Class objects representing interfaces.
