# Package javax.naming.directory

package javax.naming.directory
Extends the `javax.naming` package to provide functionality for accessing directory services.

This package defines the directory operations of the Java Naming and Directory Interface (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.

## The Directory Context

The `DirContext` interface represents a directory context . It defines methods for examining and updating attributes associated with a directory object , or directory entry as it is sometimes called.

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.

### Searches

`DirContext` 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 `search()` method. There are other overloaded forms of `search()` that support more sophisticated search filters .
