Returns:

An AutowireRepository instance

registerClass

public void registerClass(java.lang.String context,
                          java.lang.Class cl)

Parameters:

sessionFactory - The Session Factory

accessible

public boolean accessible(java.lang.String context,
                          java.lang.Class c)

Parameters:

context - The context to check

c - The class to check

true if we can autowire this class, false otherwise

createWiredObject

public java.lang.Object createWiredObject(java.lang.String context,
                                          java.lang.Class target)
                                   throws CircularReferenceException

Create an autowired object according to the indicated context

Parameters:

context - The context of the object

target - The target class of the created object

Returns:

An autowired object, or null if something went seriously wrong with trying to invoke the constructor

Throws:

CircularReferenceException

createWiredObject

protected java.lang.Object createWiredObject(java.lang.String context,
                                             java.lang.Class target,
                                             java.util.LinkedList<java.lang.Class> current,
                                             org.hibernate.Session session)
                                      throws CircularReferenceException

Create an autowired object according to the indicated context

Parameters:

context - The context of the object

target - The target class of the created object

current - A List of objects currently being autowired

session - A Hibernate session created in earlier iterations - passed to ensure only 1 is created for each autowired object and its dependencies

Returns:

An autowired object, or null if something went seriously wrong with trying to invoke the constructor

Throws:

CircularReferenceException

unwire

public void unwire(java.lang.Object o,
                   java.lang.String context)

Checks an object and any autowired dependencies for Hibernate sessions, and closes them

Parameters:

o - The object to unwire

context - The context in which the object was wired
