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

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

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

Constructor Detail

HostAddress

public HostAddress()

Creates an empty HostAdress instance

HostAddress

public HostAddress(HostAddrType addrType,
                   byte[] address)

Creates a new instance of HostAddress.

Parameters:

addrType - The type of address

address - The address

HostAddress

public HostAddress(InetAddress internetAddress)

Creates a new instance of HostAddress.

Parameters:

internetAddress - The Inet form address

Method Detail

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object that)

Returns whether one HostAddress is equal to another.

Overrides:

equals in class Object

Parameters:

that - The HostAddress to compare with

Returns:

true if the HostAddress's are equal.

getAddress

public byte[] getAddress()

Get the bytes for this address.

Returns:

The bytes of this address.

setAddress

public void setAddress(byte[] addresse)

Set the address

Parameters:

addresse - The address

computeLength

public int computeLength()

Compute the host address length

 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) 
  

encode

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

Encode the HostAddress message to a PDU.

 HostAddress :
 
 0x30 LL
   0xA0 LL 
     0x02 0x01 addr-type
   0xA1 LL 
     0x04 LL address
 

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

addrType - The address type

setAddrType

public void setAddrType(int addrType)

Set the addr-type field

Parameters:

addrType - The address type

toString

public String toString()

Overrides:

toString in class Object
