netscape.ldap.ber.stream

Class BERIntegral

Implemented Interfaces:
Serializable
Known Direct 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
Version:
1.0 seeAlso CCITT X.209
