Examples of javax.naming.Binding

javax.naming.Binding
This class represents a name-to-object binding found in a context.
A context consists of name-to-object bindings. The Binding class represents such a binding. It consists of a name and an object. The Context.listBindings() method returns an enumeration of Binding.
Use subclassing for naming systems that generate contents of a binding dynamically.
A Binding instance is not synchronized against concurrent access by multiple threads. Threads that need to access a Binding concurrently should synchronize amongst themselves and provide the necessary locking. @author Rosanna Lee @author Scott Seligman @since 1.3
