  org.apache.directory.shared.asn1.AbstractAsn1Object
      org.apache.directory.shared.kerberos.components.HostAddresses

All Implemented Interfaces:

org.apache.directory.shared.asn1.Asn1Object

public class HostAddresses
extends org.apache.directory.shared.asn1.AbstractAsn1Object

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

Constructor Detail

HostAddresses

public HostAddresses()

Creates a new instance of HostAddresses.

HostAddresses

public HostAddresses(HostAddress[] addresses)

Creates a new instance of HostAddresses.

Parameters:

addresses - The associated addresses

Method Detail

addHostAddress

public void addHostAddress(HostAddress hostAddress)

Adds an HostAddresses to the list

Parameters:

hostAddress - The address to add

contains

public boolean contains(HostAddress address)

Returns true if this HostAddresses contains a specified HostAddress.

Parameters:

address - The address we are looking for in the existing list

Returns:

true if this HostAddresses contains a specified HostAddress.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Returns true if two HostAddresses are equal.

Overrides:

equals in class Object

Parameters:

that - Th HostAddresses we want to compare with the current one

Returns:

true if two HostAddresses are equal.

getAddresses

public HostAddress[] getAddresses()

Returns the contained HostAddresss as an array.

Returns:

An array of HostAddresss.

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] )
 

encode

public ByteBuffer encode(ByteBuffer buffer)
                  throws org.apache.directory.shared.asn1.EncoderException

Encode the HostAddress message to a PDU.

 HostAddress :
 
 0x30 LL
   0x30 LL hostaddress[1] 
   0x30 LL hostaddress[1]
   ... 
   0x30 LL hostaddress[1] 
 

Specified by:

encode in interface org.apache.directory.shared.asn1.Asn1Object

Overrides:

encode in class org.apache.directory.shared.asn1.AbstractAsn1Object

Parameters:

buffer - The buffer where to put the PDU. It should have been allocated before, with the right size.

Returns:

The constructed PDU.

Throws:

org.apache.directory.shared.asn1.EncoderException
