                                       throws UserNotFoundException

Returns the previous credentials for the given user, starting with the oldest. May be an empty list if there are no historical credentials.

Throws:

UserNotFoundException - if the user could not be found

add

User add(User user,
         PasswordCredential credential)
  throws UserAlreadyExistsException,
         IllegalArgumentException,
         DirectoryNotFoundException

Creates a new user with the given details and credentials. The user details cannot be null, but the credential can be.

Parameters:

user - the user to create

credential - the encrypted password for the user, which may be null if the user's password is not yet available

Returns:

the newly created user

Throws:

UserAlreadyExistsException - if a user with the same directory and name (case-insensitive) already exists

IllegalArgumentException - if the user name, directory or any details are null, or if the credential is not encrypted

DirectoryNotFoundException

storeAttributes

void storeAttributes(User user,
                     Map<String,Set<String>> attributes,
                     boolean updateTimestamp)
              throws UserNotFoundException

Adds or updates a user's attributes with the new Map of attribute values. The attributes map represents new or updated attributes and does not replace existing attributes unless the key of an attribute matches the key of an existing attribute. Attributes with values of empty sets in the attributes parameter are removed from the user.

Parameters:

user - the user to store attributes for

attributes - new or updated attributes (attributes that don't need changing should not appear in this Map).

updateTimestamp - whether the updated timestamp for the user should be updated for this change. This SHOULD be true for attribute changes that might be of interest to other applications, and SHOULD be false for common, trivial attribute changes (for example the ones occurring during authentication)

Throws:

UserNotFoundException - user with supplied username does not exist.

update

User update(User user)
     throws UserNotFoundException,
            IllegalArgumentException

Updates all the user properties (except the username) of the user with the same directory and case-insensitive name.

If the username changes, then the rename(User, String) method must be called first, and this method may be called afterwards if other details (eg email or display name) have also changed.

Even if the username is changed in case only (eg from "mary" to "Mary") then the rename() method will be called first. This implies that the implementation of this method should only need to change the cwd_user table.

Parameters:

user - the user details, which should have the same name as the user to modify

Returns:

the updated user

Throws:

UserNotFoundException - if there is no user with the same name (case-insensitive) and directory as the user provided

IllegalArgumentException - if the user name, directory or any details are null

See Also:

rename(User, String)

updateCredential

void updateCredential(User user,
                      PasswordCredential credential,
                      int maxCredentialHistory)
               throws UserNotFoundException,
                      IllegalArgumentException

Updates the credential (password) of the user with the same directory and case-insensitive name. The credential must be encrypted.

Parameters:

user - the user whose password will be modified

credential - the new credential for the user

maxCredentialHistory - the number of old passwords for the user in which the new password must not match

Throws:

UserNotFoundException - if there is no user with the same name (case-insensitive) and directory as the user provided

IllegalArgumentException - if the credential is null or not encrypted

rename

User rename(User user,
            String newName)
     throws UserNotFoundException,
            UserAlreadyExistsException,
            IllegalArgumentException

Changes the user's name to the provided new name.

This method will be called for any change to a username including a case-only change (eg from "alice" to "Alice"). If there are changes to the username as well as to other user properties (eg email, display name) then callers must call the rename() method first followed by the update() method.

Implementations of this method will normally need to update the cwd_user table as well as cwd_membership, whereas the update() method implies a change to only the cwd_user table.

Parameters:

user - the user to rename

newName - the new name of the user

Returns:

the updated user

Throws:

UserNotFoundException - if the user cannot be found

UserAlreadyExistsException - if the new name is already used by a different user

IllegalArgumentException - if the new name is null

See Also:

update(User)

removeAttribute

void removeAttribute(User user,
                     String attributeName)
              throws UserNotFoundException

Removes the attributes for the user with the given name. Does nothing if the attribute doesn't exist.

Parameters:

user - the user whose attribute will be removed

attributeName - the name of the attribute to be removed

Throws:

UserNotFoundException - if the user cannot be found

remove

void remove(User user)
     throws UserNotFoundException

Removes the user.

Parameters:

user - the user to remove

Throws:

UserNotFoundException - if the user does not exist

search

<T> List<T> search(long directoryId,
                   EntityQuery<T> query)

Returns users matching the search query in the given directory, ordered by name. Returns an empty list if no users match.

Type Parameters:

T - the type of objects to return, which is normally either User or String

Parameters:

directoryId - the ID of the directory to search

query - the search query

Returns:

the list of matching users, or an empty list if no users match

addAll

BatchResult<User> addAll(Set<UserTemplateWithCredentialAndAttributes> users)

Bulk add users. Implementations must make sure that changes in bulk methods such as this are immediately visible to other bulk methods. For example, if this is run in a transaction, either that transaction must be committed when this method returns, or all other bulk method implementations must guarantee to reuse the same transaction.

Parameters:

users - to be added

Returns:

a list of Users that failed to be added

removeAllUsers

BatchResult<String> removeAllUsers(long directoryId,
                                   Set<String> userNames)

Bulk remove all the given users from directory. Implementations must make sure that changes in bulk methods such as this are immediately visible to other bulk methods. For example, if this is run in a transaction, either that transaction must be committed when this method returns, or all other bulk method implementations must guarantee to reuse the same transaction.

Parameters:

directoryId - the ID of the directory to remove users from

userNames - set of users to be removed

Returns:

batch result containing successes (removed users) and failures (users which were not removed)

setAttributeForAllInDirectory

void setAttributeForAllInDirectory(long directoryId,
                                   String attrName,
                                   String attrValue)

Ensures that all users in the directory with the given ID have the attribute with the given name set (only) to the single given attribute value. This means that other values of that attribute will be discarded, and the attribute will be added to users who do not have it yet.

Parameters:

directoryId - The directory to set the attributes in.

attrName - The attribute name to set.

attrValue - The attribute value to set.

getAllExternalIds

Set<String> getAllExternalIds(long directoryId)
                       throws DirectoryNotFoundException

Return all users externalId in the given directory. If a user's externalId is null or an empty String it should not be included.

Parameters:

directoryId - the ID of the directory

Returns:

set containing all externalIds with nulls filtered out

Throws:

DirectoryNotFoundException - when directory with given id does not exist

getUserCount

long getUserCount(long directoryId)
           throws DirectoryNotFoundException

Return number of users in given directory.

Parameters:

directoryId - the ID of the directory

Returns:

user count

Throws:

DirectoryNotFoundException - when directory with given id does not exist

findDirectoryIdsContainingUserName

Set<Long> findDirectoryIdsContainingUserName(String username)

Find IDs of the directories that contain user with specified username in the cache

Searches the specified directory for usernames of users with the specified external ids, returns a map from external id to username

Parameters:

directoryId - the directory to search for the users

externalIds - the external ids of the users to search for
