Class HostAddresses

java.lang.Object

org.apache.directory.shared.kerberos.components.HostAddresses

All Implemented Interfaces:

org.apache.directory.api.asn1.Asn1Object

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

Store a list of addresses. The ASN.1 grammar is :

 -- NOTE: HostAddresses is always used as an OPTIONAL field and
 -- should not be empty.
 HostAddresses   -- NOTE: subtly different from rfc1510,
                 -- but has a value mapping and encodes the same
         ::= SEQUENCE OF HostAddress

computeLength

public int computeLength()

Compute the hostAddresses length

 HostAddresses :
 
 0x30 L1 hostAddresses sequence of HostAddresses
  |
  +--> 0x30 L2[1] Hostaddress[1]
  |
  +--> 0x30 L2[2] Hostaddress[2]
  |
  ...
  |
  +--> 0x30 L2[n] Hostaddress[n]
        
  where L1 = sum( L2[1], l2[2], ..., L2[n] )
 

Specified by:

computeLength in interface org.apache.directory.api.asn1.Asn1Object

encode
