All Implemented Interfaces:

java.io.Serializable

public class AsnObjectId

extends AsnObject

implements java.io.Serializable

unsigned 32-bit integers encoded in the following format:

 MSB..LSB
 76543210
 xyyyyyyy
 .\     /
 . \   /
 .  \ /
 .   +-------- OID bits
 +------------ 0 if this is the last byte, 1 if additional bytes follow

 Output sid in the form: abcdefgh.ijklmnop.qrstuvwx.yzABCDEF

 if (abcd != 0) 
 {
   output 1.000abcd 1.efghijk 1.lmnopqr 1.stuvwxy 0.zABCDEF
 } else if (efghijk != 0) 
 {
   output 1.efghijk 1.lmnopqr 1.stuvwxy 0.zABCDEF
 } else if (lmnopqr != 0) 
 {
   output 1.lmnopqr 1.stuvwxy 0.zABCDEF
 } else if (stuvwxy != 0) 
 {
  output 1.stuvwxy 0.zABCDEF
 } else 
 {
   output 0.zABCDEF
 }
