Examples with Workflow org.apache.wiki.workflow.Workflow used on opensource projects

Example 1 with Workflow

use of org.apache.wiki.workflow.Workflow in project jspwiki by apache.

the class UserManager method setUserProfile.

/**
 * <p>
 * Saves the {@link org.apache.wiki.auth.user.UserProfile}for the user in
 * a wiki session. This method verifies that a user profile to be saved
 * doesn't collide with existing profiles; that is, the login name
 * or full name is already used by another profile. If the profile
 * collides, a <code>DuplicateUserException</code> is thrown. After saving
 * the profile, the user database changes are committed, and the user's
 * credential set is refreshed; if custom authentication is used, this means
 * the user will be automatically be logged in.
 * </p>
 * <p>
 * When the user's profile is saved successfully, this method fires a
 * {@link WikiSecurityEvent#PROFILE_SAVE} event with the WikiSession as the
 * source and the UserProfile as target. For existing profiles, if the
 * user's full name changes, this method also fires a "name changed"
 * event ({@link WikiSecurityEvent#PROFILE_NAME_CHANGED}) with the
 * WikiSession as the source and an array containing the old and new
 * UserProfiles, respectively. The <code>NAME_CHANGED</code> event allows
 * the GroupManager and PageManager can change group memberships and
 * ACLs if needed.
 * </p>
 * <p>
 * Note that WikiSessions normally attach event listeners to the
 * UserManager, so changes to the profile will automatically cause the
 * correct Principals to be reloaded into the current WikiSession's Subject.
 * </p>
 * @param session the wiki session, which may not be <code>null</code>
 * @param profile the user profile, which may not be <code>null</code>
 * @throws DuplicateUserException if the proposed profile's login name or full name collides with another
 * @throws WikiException if the save fails for some reason. If the current user does not have
 * permission to save the profile, this will be a {@link org.apache.wiki.auth.WikiSecurityException};
 * if if the user profile must be approved before it can be saved, it will be a
 * {@link org.apache.wiki.workflow.DecisionRequiredException}. All other WikiException
 * indicate a condition that is not normal is probably due to mis-configuration
