Direct Known Subclasses:

BEREnumerated, BERInteger

public abstract class BERIntegral

extends BERElement

This is the base class for integral types such as Integer and Enumerated.

 ENCODING RULE:
   Primitive Definite length.
   tag = << depends on type >>
   length = (short or long form)
   one or more contents octets hold integral value
   value in two's complement

 Example 1:  (Integer - zero)
   02 01 00
 Example 2:  (Enumerated - 1)
   0A 01 01
 Example 3:  (Integer - 300, short form)
   02 02 01 2C
 Example 4:  (Integer - 300, long form)
   02 84 00 00 01 2C
