Detailed Description

InputDescription objects are used by the PersistentIStream class to keep track of all classes it has read from a stream.

It keeps a pointer to the corresponding ClassDescription in case the class read in was actually present in the current program, a version number of the read class which may be different from the class present in the current program and a list of base class InputDescriptions.
