 * Here are all the types that we are to handle. Note that it is the type

 * that is registered and that has nothing whatsoever to do with the storage
 
14
 * class.
 
15
 *
 
16
 * Simple types
 
17
 * integers: char, short, int, long (signed and unsigned)
 
18
 * floats: float, double
 
19
 *
 
20
 * Complex types:
 
21
 * VARCHAR, VARCHAR2 - Strings with length (maxlen is given in the declaration)
 
22
 * Arrays of simple types and of VARCHAR, VARCHAR2 (size given in declaration)
 
23
 * Records build of simple types, arrays and other structs.

25
 * Complicating things:
 
26
 * typedefs and struct names!

28
 * Conclusion:
 
29
 * This is a typically recursive definition. A structure of typed list elements
