Method Detail

isReadOnly

boolean isReadOnly()

Allows to inquire whether this identity service implementation provides read-only access to the user repository, false otherwise.

Read only identity service implementations do not support the following methods:

• newUser(String)
• saveUser(User)
• deleteUser(String)
• newGroup(String)
• saveGroup(Group)
• deleteGroup(String)
• createMembership(String, String)
• deleteMembership(String, String)

If these methods are invoked on a read-only identity service implementation, the invocation will throw an UnsupportedOperationException.

Returns:

true if this identity service implementation provides read-only access to the user repository, false otherwise.

newUser

User newUser(String userId)

Creates a new user. The user is transient and must be saved using saveUser(User).

Parameters:

userId - id for the new user, cannot be null.

Throws:

UnsupportedOperationException - if identity service implementation is read only. See isReadOnly()

AuthorizationException - if the user has no Permissions.CREATE permissions on Resources.USER.

saveUser

void saveUser(User user)

Saves the user. If the user already existed, the user is updated.

Parameters:

user - user to save, cannot be null.

Throws:

RuntimeException - when a user with the same name already exists.

UnsupportedOperationException - if identity service implementation is read only. See isReadOnly()

AuthorizationException - if the user has no Permissions.UPDATE permissions on Resources.USER (update existing user) or if user has no Permissions.CREATE permissions on Resources.USER (save new user).

createUserQuery

UserQuery createUserQuery()

Creates a UserQuery that allows to programmatically query the users.

deleteUser

void deleteUser(String userId)

Parameters:

userId - id of user to delete, cannot be null. When an id is passed for an unexisting user, this operation is ignored.

Throws:

UnsupportedOperationException - if identity service implementation is read only. See isReadOnly()

AuthorizationException - if the user has no Permissions.DELETE permissions on Resources.USER.

newGroup

Group newGroup(String groupId)

Creates a new group. The group is transient and must be saved using saveGroup(Group).

Parameters:

groupId - id for the new group, cannot be null.

Throws:

UnsupportedOperationException - if identity service implementation is read only. See isReadOnly()

AuthorizationException - if the user has no Permissions.CREATE permissions on Resources.GROUP.

createGroupQuery

GroupQuery createGroupQuery()

Creates a GroupQuery thats allows to programmatically query the groups.

saveGroup

void saveGroup(Group group)

Saves the group. If the group already existed, the group is updated.

Parameters:

group - group to save. Cannot be null.

Throws:

RuntimeException - when a group with the same name already exists.

UnsupportedOperationException - if identity service implementation is read only. See isReadOnly()

AuthorizationException - if the user has no Permissions.UPDATE permissions on Resources.GROUP (update existing group) or if user has no Permissions.CREATE permissions on Resources.GROUP (save new user).

deleteGroup

void deleteGroup(String groupId)

Deletes the group. When no group exists with the given id, this operation is ignored.

Parameters:

groupId - id of the group that should be deleted, cannot be null.

Throws:

UnsupportedOperationException - if identity service implementation is read only. See isReadOnly()

AuthorizationException - if the user has no Permissions.DELETE permissions on Resources.GROUP.

createMembership

void createMembership(String userId,
                      String groupId)

Parameters:

userId - the userId, cannot be null.

groupId - the groupId, cannot be null.

Throws:

RuntimeException - when the given user or group doesn't exist or when the user is already member of the group.

UnsupportedOperationException - if identity service implementation is read only. See isReadOnly()

AuthorizationException - if the user has no Permissions.CREATE permissions on Resources.GROUP_MEMBERSHIP.

deleteMembership

void deleteMembership(String userId,
                      String groupId)

Delete the membership of the user in the group. When the group or user don't exist or when the user is not a member of the group, this operation is ignored.

Parameters:

userId - the user's id, cannot be null.

groupId - the group's id, cannot be null.

Throws:

UnsupportedOperationException - if identity service implementation is read only. See isReadOnly()

Checks if the password is valid for the given user. Arguments userId and password are nullsafe.

setAuthenticatedUserId

void setAuthenticatedUserId(String authenticatedUserId)

Passes the authenticated user id for this thread. All service method (from any service) invocations done by the same thread will have access to this authenticatedUserId. Should be followed by a call to clearAuthentication() once the interaction is terminated.

Parameters:

authenticatedUserId - the id of the current user.

groups - the groups of the current user.

setAuthentication

void setAuthentication(String userId,
                       List<String> groups)
