Java MUCUser.getStatus方法代码示例

/**
 * Creates the room according to some default configuration, assign the requesting user
 * as the room owner, and add the owner to the room but not allow anyone else to enter
 * the room (effectively "locking" the room). The requesting user will join the room
 * under the specified nickname as soon as the room has been created.<p>
 *
 * To create an "Instant Room", that means a room with some default configuration that is
 * available for immediate access, the room's owner should send an empty form after creating
 * the room. {@link #sendConfigurationForm(Form)}<p>
 *
 * To create a "Reserved Room", that means a room manually configured by the room creator
 * before anyone is allowed to enter, the room's owner should complete and send a form after
 * creating the room. Once the completed configutation form is sent to the server, the server
 * will unlock the room. {@link #sendConfigurationForm(Form)}
 *
 * @param nickname the nickname to use.
 * @throws XMPPException if the room couldn't be created for some reason
 *          (e.g. room already exists; user already joined to an existant room or
 *          405 error if the user is not allowed to create the room)
