Retrieves the state of an object for binding.
Object getStateToBind(Object obj, Name name, Context nameCtx, Hashtable<?,?> environment) throws NamingException
NamingManager.getStateToBind() successively loads in state factories and invokes this method on them until one produces a non-null answer. DirectoryManager.getStateToBind() successively loads in state factories. If a factory implements DirStateFactory, then DirectoryManager invokes DirStateFactory.getStateToBind(); otherwise it invokes StateFactory.getStateToBind().
When an exception is thrown by a factory, the exception is passed on to the caller of NamingManager.getStateToBind() and 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.
nameCtx parameters may
optionally be used to specify the name of the object being created.
See the description of "Name and Context Parameters" in
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 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.
obj- A non-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
nameparameter is specified, or null if
nameis relative to the default initial context.
environment- The possibly null environment to be used in the creation of the object's state.
NamingException- if this factory encountered an exception while attempting to get the object's state, and no other factories are to be tried.
