Class BERInteger

java.lang.Object

netscape.ldap.ber.stream.BERElement

netscape.ldap.ber.stream.BERIntegral

netscape.ldap.ber.stream.BERInteger

All Implemented Interfaces:

Serializable

public class BERInteger
extends BERIntegral

This class is for the Integer object.

ENCODING RULE:
  Primitive Definite length.
  tag = 0x02
  length = (short or long form)
  one or more contents octets hold integer
  value in two's complement

Example 1:  (zero)
  02 01 00
Example 2:  (1)
  02 01 01
Example 3:  (300 - short form)
  02 02 01 2C
Example 4:  (300 - long form)
  02 84 00 00 01 2C
