It is designed to be 39 independent of any specific naming or directory service 40 implementation. Thus a variety of services--new, emerging, and 41 already deployed ones--can be accessed in a common way. 42 43 <p> 44 This package allows applications to retrieve and update attributes 45 associated with objects stored in a directory, and to search for 46 objects using specified attributes. 47 48 <h2>The Directory Context</h2> 49 50 The <code>DirContext</code> 51 interface represents a <em>directory context</em>. 52 It defines methods for examining and updating attributes associated with a 53 <em>directory object</em>, or <em>directory entry</em> as it is sometimes 54 called. 55 <p> 56 You use <code>getAttributes()</code> to retrieve the attributes 57 associated with a directory object (for which you supply the name). 58 Attributes are modified using <code>modifyAttributes()</code>. 59 You can add, replace, or remove attributes and/or attribute values 60 using this operation. 61 <p> 62 <code>DirContext</code> also behaves as a naming context 63 by extending the <code>Context</code> interface in the <code>javax.naming</code> package. 64 This means that any directory object can also provide 65 a naming context. 66 For example, the directory object for a person might contain 67 the attributes of that person, and at the same time provide 68 a context for naming objects relative to that person 69 such as his printers and home directory. 70 71 <h3>Searches</h3> 72 <code>DirContext</code> contains methods for 73 performing content-based searching of the directory. 74 In the simplest and most common form of usage, the application 75 specifies a set of attributes--possibly with specific 76 values--to match, and submits this attribute set, to the 77 <code>search()</code> method. 78 There are other overloaded forms of <code>search()</code> 79 that support more sophisticated <em>search filters</em>. 80 81 82 <h2>Package Specification</h2> 83 84 The JNDI API Specification and related documents can be found in the 85 {@extLink jndi_overview JNDI documentation}. 86 87 @since 1.3 88 89 </body> 90 </html>
