//
|
|
// Purpose:
|
|
// This is a base class for state objects that can be transmitted
|
|
// across a connection. It inherits an interface from Subject so it
|
|
// can tell its observers when it changes.

// Brad Whitlock, Mon Feb 11 15:26:34 PST 2002

// Added a new method to create compatible types.

|
|
// Brad Whitlock, Wed Jul 23 11:15:49 PDT 2003
|
|
// Added a new method to create a new instance that does not have to
|
|
// be initialized from the calling object.
|
|
//
|
|
// Kathleen Bonnell, Tue Jun 20 16:02:38 PDT 2006
|
|
// Added virtual method TypeName so that derived classes can have their
|
|
// names printed in log files.
