Class HostAddress

java.lang.Object

org.apache.directory.shared.kerberos.components.HostAddress

All Implemented Interfaces:

org.apache.directory.api.asn1.Asn1Object

public class HostAddress
extends java.lang.Object
implements org.apache.directory.api.asn1.Asn1Object

Provides host address information. The ASN.1 grammar for this structure is :

 HostAddress     ::= SEQUENCE  {
        addr-type       [0] Int32,
        address         [1] OCTET STRING
 }

 HostAddress :
 
 0x30 L1 hostAddress sequence
  |
  +--> 0xA0 L2 addrType tag
  |     |
  |     +--> 0x02 L2-1 addrType (int)
  |
  +--> 0xA1 L3 address tag
        |
        +--> 0x04 L3-1 address (OCTET STRING)
        
  where L1 = L2 + length(0xA0) + length(L2) +
             L3 + length(0xA1) + length(L3) 
  and
  L2 = L2-1 + length(0x02) + length( L2-1) 
  L3 = L3-1 + length(0x04) + length( L3-1) 
  

Specified by:
