This package defines the directory operations of the Java Naming and Directory InterfaceTM (JNDI). JNDI provides naming and directory functionality to applications written in the Java programming language. It is designed to be independent of any specific naming or directory service implementation. Thus a variety of services--new, emerging, and already deployed ones--can be accessed in a common way.
This package allows applications to retrieve and update attributes associated with objects stored in a directory, and to search for objects using specified attributes.
You use getAttributes() to retrieve the attributes associated with a directory object (for which you supply the name). Attributes are modified using modifyAttributes(). You can add, replace, or remove attributes and/or attribute values using this operation.
DirContext also behaves as a naming context by extending the Context interface in the javax.naming package. This means that any directory object can also provide a naming context. For example, the directory object for a person might contain the attributes of that person, and at the same time provide a context for naming objects relative to that person such as his printers and home directory.
