/**
* This interface represents a builder that creates object factories.
*<p>
* The JNDI framework allows for object implementations to
* be loaded in dynamically via <em>object factories</em>.
* 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 <tt>NamingManager.setObjectFactoryBuilder()</tt> with an ObjectFactoryBuilder,
* which contains the program-defined way of creating/loading
* object factories.
* Any <tt>ObjectFactoryBuilder</tt> implementation must implement this
* interface that for creating object factories.
