Method Detail

isMember

boolean isMember(java.lang.String userName,
                 java.lang.String groupName)
                 throws java.rmi.RemoteException,
                        InvalidAuthorizationTokenException,
                        InvalidAuthenticationException

Returns true if the user represented by userName is a member of groupName

Parameters:

userName - The user to check

groupName - The group to check.

Returns:

true if a member, false otherwise.

Throws:

java.rmi.RemoteException - A communication error occurred - the Crowd server may not be available.

InvalidAuthorizationTokenException - The application (not the user) was not authenticated correctly.

InvalidAuthenticationException - application authentication is not valid

addMembership

void addMembership(java.lang.String userName,
                   java.lang.String groupName)
                   throws java.rmi.RemoteException,

GroupNotFoundException - the group could not be found

UserNotFoundException - the user could not be found

ApplicationPermissionException - This application does not have permission to update group memberships.

InvalidAuthenticationException - application authentication is not valid

removeMembership

void removeMembership(java.lang.String userName,
                      java.lang.String groupName)

Parameters:

userName - The user to remove

groupName - The group the user will be added from

Throws:

java.rmi.RemoteException - A communication error occurred - the Crowd server may not be available.

InvalidAuthenticationException - application authentication is not valid

MembershipNotFoundException - Unable to find membership

getMemberships

java.util.List getMemberships(java.lang.String userName)
                              throws java.rmi.RemoteException,

                                     InvalidAuthenticationException

Deprecated. Since 1.4

Obtains a list of all groups that the user identified by userName belongs to, sorted naturally.

This can be a slow call, particularly on some LDAP directories, and so should be avoided. Use isMember() instead.

Parameters:

userName - The user whose group memberships are desired.

Returns:

A List of Strings containing all the groups the user belongs to, or an empty List

Throws:

java.rmi.RemoteException - A communication error occurred - the Crowd server may not be available.

InvalidAuthorizationTokenException - The application (not the user) was not authenticated correctly.

UserNotFoundException - If the user could not be found.

InvalidAuthenticationException - application authentication is not valid

getMembers

java.util.List getMembers(java.lang.String groupName)
                          throws java.rmi.RemoteException,
                                 InvalidAuthorizationTokenException,
                                 GroupNotFoundException,
                                 InvalidAuthenticationException

Obtains a list of all users in the group identified by groupName, sorted naturally.

This is a fairly fast call, but implementers should still be using isMember() wherever practicable.

Parameters:

groupName - The group whose member users are desired.

Returns:

A List of Strings containing all the users in the group, or an empty list.

Throws:

java.rmi.RemoteException - A communication error occurred - the Crowd server may not be available.

InvalidAuthorizationTokenException - The application (not the user) was not authenticated correctly.

GroupNotFoundException - If the group could not be found.

InvalidAuthenticationException - application authentication is not valid
