Need help in design

[Subhashini]

Hi.......
I get jummbled in a situation which is as follows:

I need to design a class which will handle a binary
message(i.e. able to parse it).

The message is an information element whose structure will be
as follows:

The contents of each element is either one value (Primitive)
or one or more
information elements (Constructor), as shown in Figure.
