Interface ObjectFactoryBuilder
- public interface ObjectFactoryBuilder
This interface represents a builder that creates object factories.
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 Summary |
ObjectFactory |
createObjectFactory(java.lang.Object obj,
java.util.Hashtable environment)
Creates a new object factory using the environment supplied. |
createObjectFactory
public ObjectFactory createObjectFactory(java.lang.Object obj,
java.util.Hashtable environment)
throws NamingException
- 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.
