| Methods Summary |
|---|
| public static com.imaginary.lwp.Identifier | currentIdentifier()Provides a client application with its identifier so that
it can pass it to a transactional method.
return currentIdentifier((AuthenticationRole)null);
|
| public static com.imaginary.lwp.Identifier | currentIdentifier(java.lang.Object cred)
return (Identifier)identifiers.get(new AuthenticationRole(cred));
|
| public static com.imaginary.lwp.Identifier | currentIdentifier(AuthenticationRole r)
return (Identifier)identifiers.get(r);
|
| public boolean | equals(java.lang.Object ob)
if( ob instanceof Identifier ) {
Identifier id = (Identifier)ob;
if( key != id.key ) {
return false;
}
return true;
}
return false;
|
| private static long | getRandomNumber()Generates a secure, random long used for key generation.
byte[] value = new byte[60];
long l = 0;
if( randomizer == null ) {
randomizer = new SecureRandom();
}
randomizer.nextBytes(value);
for(int i=0; i<60; i++) {

| public static com.imaginary.lwp.Identifier | getServerID()
if( serverID == null ) {
serverID = new Identifier("LWPSERVER");
}
return serverID;
|
| public java.lang.String | getUserID()
return userID;
|
| public int | hashCode()A hash code based on the key.
return (new Long(key)).hashCode();
|
| static boolean | isAuthenticated(com.imaginary.lwp.Identifier id)Looks through the list of authenticated users for
any authentication matching the specified identifier.

| public static com.imaginary.lwp.Identifier | login(java.lang.String uid, java.lang.String pw)Authenticates the specified user ID against the specified password.
This method finds the server and sends the user ID and password
to it for authentication. If the password does not match the
currently stored password, then an exception is thrown. Otherwise
it will store the identifier the server hands back. This method
authenticates for a default role.
return login(uid, pw, null);
|
| public static com.imaginary.lwp.Identifier | login(java.lang.String uid, java.lang.String pw, AuthenticationRole r)Authenticates the specified user ID against the specified password.
This method finds the server and sends the user ID and password
to it for authentication. If the password does not match the
currently stored password, then an exception is thrown. Otherwise
it will store the identifier the server hands back.
String url = System.getProperty(LWPProperties.RMI_URL);

throws out people who have not touched the system in a while.
