public class SessionStub

extends java.lang.Object

This is a helper class intended to do a subset of the work done by com.blackboard.security.CISession. A SessionStub object is just that, a 'struct'-style stub for session data. The method of note for Building Block developers is disassociateCurrentSessionAndUser() which can be used in logout processing.

Method Detail

getSessionId

Returns the Blackboard assigned unique id for this user's session.

getMd5SessionId

public java.lang.String getMd5SessionId()

Returns the Blackboard assigned unique id for this user's session as an MD5 hashed string.

associateSessionWithUser

public void associateSessionWithUser(java.lang.String userName)
                              throws BbAuthenticationFailedException,
                                     BbSecurityException

associateSessionWithUser If the userId is associated with a valid user record in the database, then the current session should be associated with that user record, in the database. Please note that if the system is currently set to authenticate against an external authority, then the userName parameter will be treated as the user's "batch uid" ( external userid ). Also, note that if the system is set to auto-populate, then every user record's user_id will be the same as their batch_uid -- except for the administrator, whose account is expected to be created at install-time

updateLastLoginTime

public void updateLastLoginTime(java.lang.String userName)
                         throws BbAuthenticationFailedException,

toString

public java.lang.String toString()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Overrides:

toString in class java.lang.Object

Returns:

a string representation of the object.
