Retrieves the state of an object for binding given the object and attributes to be transformed.

DirectoryManager.getStateToBind() successively loads in state factories. If a factory implements DirStateFactory, DirectoryManager invokes this method; otherwise, it invokes StateFactory.getStateToBind(). It does this until a factory produces a non-null answer.

When an exception is thrown by a factory, the exception is passed on to the caller of DirectoryManager.getStateToBind(). The search for other factories that may produce a non-null answer is halted. A factory should only throw an exception if it is sure that it is the only intended factory and that no other factories should be tried. If this factory cannot create an object using the arguments supplied, it should return null.

The name and nameCtx parameters may optionally be used to specify the name of the object being created. See the description of "Name and Context Parameters" in ObjectFactory.getObjectInstance() for details. If a factory uses nameCtx it should synchronize its use against concurrent access, since context implementations are not guaranteed to be thread-safe.

The name, inAttrs, and environment parameters are owned by the caller. The implementation will not modify these objects or keep references to them, although it may keep references to clones or copies. The object returned by this method is owned by the caller. The implementation will not subsequently modify it. It will contain either a new Attributes object that is likewise owned by the caller, or a reference to the original inAttrs parameter.

Parameters:

obj     A possibly null object whose state is to be retrieved.

name     The name of this object relative to nameCtx, or null if no name is specified.

nameCtx     The context relative to which the name parameter is specified, or null if name is relative to the default initial context.

environment     The possibly null environment to be used in the creation of the object's state.

inAttrs     The possibly null attributes to be bound with the object. The factory must not modify inAttrs.

Returns: A Result containing the object's state for binding and the corresponding attributes to be bound; null if the object don't use this factory.

Exceptions:

NamingException If this factory encountered an exception while attempting to get the object's state, and no other factories are to be tried.

`obj`		A possibly null object whose state is to be retrieved.
`name`		The name of this object relative to `nameCtx`, or null if no name is specified.
`nameCtx`		The context relative to which the `name` parameter is specified, or null if `name` is relative to the default initial context.
`environment`		The possibly null environment to be used in the creation of the object's state.
`inAttrs`		The possibly null attributes to be bound with the object. The factory must not modify `inAttrs`.
