Class HostAddress

java.lang.Object
  sun.security.mule.krb5.internal.HostAddress

All Implemented Interfaces:

Cloneable

public class HostAddress
extends Object
implements Cloneable

Implements the ASN.1 HostAddress type.

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

This definition reflects the Network Working Group RFC 4120 specification available at http://www.ietf.org/rfc/rfc4120.txt.

Constructor Summary

HostAddress()

HostAddress(sun.security.util.DerValue encoding)
Constructs a host address from a single DER-encoded value.

HostAddress(InetAddress inetAddress)

HostAddress(int new_addrType, byte[] new_address)
Creates a HostAddress from the specified address and address type.

Method Summary

byte[]	asn1Encode() Encodes a HostAddress object.
Object	clone()
boolean	equals(Object obj)
InetAddress	getInetAddress() Gets the InetAddress of this HostAddress.
int	hashCode()
static HostAddress	parse(sun.security.util.DerInputStream data, byte explicitTag, boolean optional) Parses (unmarshal) a host address from a DER input stream.

Constructor Detail

HostAddress

public HostAddress()
            throws UnknownHostException

Throws:

UnknownHostException

HostAddress

public HostAddress(int new_addrType,
                   byte[] new_address)
            throws KrbApErrException,
                   UnknownHostException

Creates a HostAddress from the specified address and address type.

Parameters:

new_addrType - the value of the address type which matches the defined address family constants in the Berkeley Standard Distributions of Unix.

new_address - network address.

Throws:

KrbApErrException - if address type and address length do not match defined value.

UnknownHostException

HostAddress

public HostAddress(InetAddress inetAddress)

HostAddress

public HostAddress(sun.security.util.DerValue encoding)
            throws Asn1Exception,
                   IOException

Constructs a host address from a single DER-encoded value.

Parameters:

encoding - a single DER-encoded value.

Throws:

Asn1Exception - if an error occurs while decoding an ASN1 encoded data.

IOException - if an I/O error occurs while reading encoded data.

Method Detail

clone

public Object clone()

Overrides:

clone in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

getInetAddress

public InetAddress getInetAddress()
                           throws UnknownHostException

Gets the InetAddress of this HostAddress.

Returns:

the IP address for this specified host.

Throws:

if - no IP address for the host could be found.

UnknownHostException

asn1Encode

public byte[] asn1Encode()
                  throws Asn1Exception,
                         IOException

Encodes a HostAddress object.

Returns:

a byte array of encoded HostAddress object.

Throws:

Asn1Exception - if an error occurs while decoding an ASN1 encoded data.

IOException - if an I/O error occurs while reading encoded data.

parse

public static HostAddress parse(sun.security.util.DerInputStream data,
                                byte explicitTag,
                                boolean optional)
                         throws Asn1Exception,
                                IOException

Parses (unmarshal) a host address from a DER input stream. This form parsing might be used when expanding a value which is part of a constructed sequence and uses explicitly tagged type.

Parameters:

data - the Der input stream value, which contains one or more marshaled value.

explicitTag - tag number.

optional - indicates if this data field is optional

Returns:

an instance of HostAddress.

Throws:

Asn1Exception - on error.

IOException - if an I/O error occurs while reading encoded data.
