Method Detail

isLicensedToAddMoreUsers

public boolean isLicensedToAddMoreUsers()

Specified by:

isLicensedToAddMoreUsers in interface UserAccessor

Overrides:

isLicensedToAddMoreUsers in class DefaultUserAccessor

addMembership

public void addMembership(com.atlassian.user.Group group,
                          com.atlassian.user.User user)

Adds the specified user to this group.

Specified by:

addMembership in interface UserAccessor

Overrides:

addMembership in class DefaultUserAccessor

Throws:

InsufficientPrivilegeException - if the currently logged in user does not have the permissions to add this user to this group. Check permissions using Permission.EDIT on PermissionManager on the group first.

removeMembership

public boolean removeMembership(com.atlassian.user.Group group,
                                com.atlassian.user.User user)

Removes the specified user from this group.

Specified by:

removeMembership in interface UserAccessor

Overrides:

removeMembership in class DefaultUserAccessor

Throws:

InsufficientPrivilegeException - if the currently logged in user does not have the permissions to remove this user from this group. Check permissions using Permission.REMOVE and PermissionManager on the group first.

getUserByName

public ConfluenceUser getUserByName(String name)

Description copied from interface: UserAccessor

Returns the ConfluenceUser with the supplied user name or null if the user doesn't exist or the supplied name is null.

Note that user name lookups are case-insensitive, so the user you get back may not have exactly the same name as the name passed to this method.

Parameters:

name - the user name of the user

Returns:

the ConfluenceUser with the supplied user name or null.

getUserByKey

public ConfluenceUser getUserByKey(com.atlassian.sal.api.user.UserKey key)

Description copied from interface: UserAccessor

Returns the user with the specified user key, or null if the user has never existed or the key is null.

WARNING: This method can return deleted users. Use UserAccessor.getExistingUserByKey(com.atlassian.sal.api.user.UserKey) to get only users that exist.

getExistingUserByKey

public ConfluenceUser getExistingUserByKey(com.atlassian.sal.api.user.UserKey key)

Description copied from interface: UserAccessor

Returns the user with the specified user key, or null if the user doesn't exist or the key is null.

exists

public boolean exists(String name)

Description copied from interface: UserAccessor

Returns true if a user exists with the given username. This method is significantly faster than getUser(name) != null.

Parameters:

name - username of the user

Returns:

true if a user exists with the given username

createUser

public ConfluenceUser createUser(com.atlassian.user.User userTemplate,
                                 com.atlassian.user.security.password.Credential credential)

Description copied from interface: UserAccessor

Specified by:

createUser in interface UserAccessor

createUser in class DefaultUserAccessor

addGroup

public com.atlassian.user.Group addGroup(String groupname)

Adds a group with the specified name.

Specified by:

addGroup in interface UserAccessor

Overrides:

addGroup in class DefaultUserAccessor

Returns:

the group created

Throws:

InsufficientPrivilegeException - if the current user does not have permission to add this group

createGroup

public com.atlassian.user.Group createGroup(String groupname)

Method was added for consistency. We will need to decide whether we want to lowercase all group names upon creation. Currently createGroup() preserves the casing of the name and addGroup() will lowercase the name. Both methods were in use by Confluence, but only one overwritten to publish an event.

Specified by:

createGroup in interface UserAccessor

Overrides:

createGroup in class DefaultUserAccessor

removeGroup

public void removeGroup(com.atlassian.user.Group group)

Description copied from interface: UserAccessor

Removes the specified group. Does nothing if the group does not exist.

Specified by:

removeGroup in interface UserAccessor

Overrides:

removeGroup in class DefaultUserAccessor

Throws:

InsufficientPrivilegeException - if you do not have sufficient permissions to remove this group. Check permissions using Permission.REMOVE and PermissionManager on the group first.

removeUser

public void removeUser(com.atlassian.user.User user)

Removes the specified user.

Specified by:

removeUser in interface UserAccessor

Overrides:

removeUser in class DefaultUserAccessor

Throws:

IllegalArgumentException - if the specified user is null

InsufficientPrivilegeException - if the currently logged in user does not permissions to remove this user. Check permissions using Permission.REMOVE and PermissionManager on the user first.

getUserNamesWithConfluenceAccess

public List<String> getUserNamesWithConfluenceAccess()

Description copied from interface: UserAccessor

Returns the names of all users with access to use Confluence. If you only need to know the number of users, you should call UserChecker.getNumberOfRegisteredUsers(), as that caches its results.

See Also:

UserChecker

countUsersWithConfluenceAccess

public int countUsersWithConfluenceAccess()

See Also:

UserChecker

countLicenseConsumingUsers

public int countLicenseConsumingUsers()

Description copied from interface: UserAccessor

Returns the number of users which have access to use Confluence AND consume a Confluence license. Callers are strongly recommended to use the UserChecker.getNumberOfRegisteredUsers() to retrieve this info, as that caches its results.

See Also:

UserChecker

getUsersWithConfluenceAccess

public com.atlassian.user.search.page.Pager<com.atlassian.user.User> getUsersWithConfluenceAccess()

Returns all the users with access to use Confluence.

Specified by:

getUsersWithConfluenceAccess in interface UserAccessor

isDeactivated

public boolean isDeactivated(String username)

Description copied from interface: UserAccessor

Returns true if the user with the specified username exists and is unable to log in, otherwise false. Returns false if the username is null.

Specified by:

isDeactivated in interface UserAccessor

Returns:

true if the user with the specified username exists and is unable to log in, otherwise false.

isDeactivated

public boolean isDeactivated(com.atlassian.user.User user)

Description copied from interface: UserAccessor

Returns true if the user exists and is unable to log in, otherwise false. Returns false if the user is null.

Specified by:

isDeactivated in interface UserAccessor

Returns:

true if the user exists and is unable to log in, otherwise false.

savePersonalInformation

public void savePersonalInformation(PersonalInformation newInfo,
                                    PersonalInformation oldInfo)

deactivateUser

public void deactivateUser(com.atlassian.user.User user)

Description copied from interface: UserAccessor

Deactivate the specified user, which prevents them logging in. Does nothing if the user is already deactivated.

Specified by:

deactivateUser in interface UserAccessor

reactivateUser

public void reactivateUser(com.atlassian.user.User user)

Description copied from interface: UserAccessor

Marks the specified user as active, which allows them to log in. Does nothing if the user is already active.

Specified by:

reactivateUser in interface UserAccessor

isReadOnly

public boolean isReadOnly(com.atlassian.user.User user)

Description copied from interface: UserAccessor

Returns true if the user cannot be modified or removed. However, returning false does necessarily confirm that the user can be modified or removed. Depending on the user management configuration, it is not always possible for Confluence to determine whether a user is read-only.

In an internal-only user management configuration, this method always returns false.

isReadOnly

public boolean isReadOnly(com.atlassian.user.Group group)

Description copied from interface: UserAccessor

Returns true if the group cannot be modified or removed. However, returning false does necessarily confirm that the group can be modified or removed. Depending on the user management configuration, it is not always possible for Confluence to determine whether a group is read-only. Indeed, groups can span across multiple directories with different access control mechanisms, so it may be possible to modify certain memberships of a group but not others.

In an internal-only user management configuration, this method always returns false.
