## org.jivesoftware.openfire.user
Class User

    java.lang.Object
      org.jivesoftware.openfire.user.User

All Implemented Interfaces:
  Externalizable, Serializable, Cacheable, org.xmpp.resultsetmanagement.Result

    public class User

extends Object
implements Cacheable, Externalizable, org.xmpp.resultsetmanagement.Result

Encapsulates information about a user. New users are created using `UserManager.createUser(String, String, String, String)`. All user properties are loaded on demand and are read from the `ofUserProp` database table. The currently-installed `UserProvider` is used for setting all other user data and some operations may not be supported depending on the capabilities of the `UserProvider`.

Constructor Detail

### User

    public User()

  Constructor added for Externalizable. Do not use this constructor.

### User

    public User(String username,
                String name,
                String email,
                Date creationDate,
                Date modificationDate)

  Constructs a new user. Normally, all arguments can be `null` except the username. However, a UserProvider -may- require a name or email address. In those cases, the isNameRequired or isEmailRequired UserProvider tests indicate whether `null` is allowed. Typically, User objects should not be constructed by end-users of the API. Instead, user objects should be retrieved using `UserManager.getUser(String)`.

  Parameters:
    `username` - the username.
    `name` - the name.
    `email` - the email address.
    `creationDate` - the date the user was created.
    `modificationDate` - the date the user was last modified.

Method Detail

### getPropertyValue

    public static String getPropertyValue(String username,
                                          String propertyName)

  Returns the value of the specified property for the given username. This method is an optimization to avoid loading a user to get a specific property.

  Parameters:

    `propertyName` - the name of the property to return its value.
  Returns:
    the value of the specified property for the given username.
