Detailed Description

Represents a variable type.

Author:

Wolfgang Wieser ] wwieser (a) gmx <*> de [

The ID field stores the ID of the type if array=0 and the type of the elements if array=1. I.e. an array of integers has id=Int,array=1, an array of arrays as well as an array of objects has id=Ptr,array=1, an object (pointer) has id=Ptr,array=0 and a simple integer has id=Int,array=0.

This class is C++-safe.
