The JNDI framework allows for object implementations to
be loaded in dynamically via object factories.
For example, when looking up a printer bound in the name space,
if the print service binds printer names to References, the printer
Reference could be used to create a printer object, so that
the caller of lookup can directly operate on the printer object
after the lookup. An ObjectFactory is responsible for creating
objects of a specific type. JNDI uses a default policy for using
and loading object factories. You can override this default policy
by calling NamingManager.setObjectFactoryBuilder()
with an ObjectFactoryBuilder,
which contains the program-defined way of creating/loading
object factories.
Any ObjectFactoryBuilder
implementation must implement this
interface that for creating object factories.

Method Details
-
createObjectFactory
Creates a new object factory using the environment supplied.The environment parameter is owned by the caller. The implementation will not modify the object or keep a reference to it, although it may keep a reference to a clone or copy.
- Parameters:
obj
- The possibly null object for which to create a factory.environment
- Environment to use when creating the factory. Can be null.- Returns:
- A non-null new instance of an ObjectFactory.
- Throws:
NamingException
- If an object factory cannot be created.
