| Extends the <tt>javax.naming</tt> package to provide functionality | |
| for accessing directory services. | |
| <p> | |
| This package defines the directory operations of the Java Naming and | |
| Directory Interface<font size=-2><sup>TM</sup></font> (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. | |
| <p> | |
| This package allows applications to retrieve and update attributes | |
| associated with objects stored in a directory, and to search for | |
| objects using specified attributes. | |
| <h4>The Directory Context</h4> | |
| The <tt>DirContext</tt> | |
| interface represents a <em>directory context</em>. | |
| It defines methods for examining and updating attributes associated with a | |
| <em>directory object</em>, or <em>directory entry</em> as it is sometimes | |
| called. | |
| <p> | |
| You use <tt>getAttributes()</tt> to retrieve the attributes | |
| associated with a directory object (for which you supply the name). | |
| Attributes are modified using <tt>modifyAttributes()</tt>. | |
| You can add, replace, or remove attributes and/or attribute values | |
| using this operation. | |
| <p> | |
| <tt>DirContext</tt> also behaves as a naming context | |
| by extending the <tt>Context</tt> interface in the <tt>javax.naming</tt> 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. | |
| <h4>Searches</h4> | |
| <tt>DirContext</tt> contains methods for | |
| performing content-based searching of the directory. | |
| In the simplest and most common form of usage, the application | |
| specifies a set of attributes--possibly with specific | |
| values--to match, and submits this attribute set, to the | |
| <tt>search()</tt> method. | |
| There are other overloaded forms of <tt>search()</tt> | |
| that support more sophisticated <em>search filters</em>. | |
| <h2>Package Specification</h2> | |

| <a href="../../../../technotes/guides/jndi/index.html">JNDI documentation</a>. | |
