sun.security.mule.krb5.internal
Class AuthorizationData

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

All Implemented Interfaces:

Cloneable

public class AuthorizationData
extends Object
implements Cloneable

In RFC4120, the ASN.1 AuthorizationData is defined as: AuthorizationData ::= SEQUENCE OF SEQUENCE { ad-type [0] Int32, ad-data [1] OCTET STRING } Here, two classes are used to implement it and they can be represented as follows: AuthorizationData ::= SEQUENCE OF AuthorizationDataEntry AuthorizationDataEntry ::= SEQUENCE { ad-type[0] Int32, ad-data[1] OCTET STRING }

Constructor Summary

AuthorizationData(AuthorizationDataEntry new_entry)

AuthorizationData(AuthorizationDataEntry[] new_entries)

AuthorizationData(sun.security.util.DerValue der)
Constructs a new AuthorizationData, instance.

Method Summary

byte[]	asn1Encode() Encodes an AuthorizationData object.
Object	clone()
static AuthorizationData	parse(sun.security.util.DerInputStream data, byte explicitTag, boolean optional) Parse (unmarshal) an AuthorizationData object from a DER input stream.
String	toString()
void	writeAuth(CCacheOutputStream cos) Writes AuthorizationData data fields to a output stream.

Constructor Detail

AuthorizationData

public AuthorizationData(AuthorizationDataEntry[] new_entries)
                  throws IOException

Throws:

IOException

AuthorizationData

public AuthorizationData(AuthorizationDataEntry new_entry)

AuthorizationData

public AuthorizationData(sun.security.util.DerValue der)
                  throws Asn1Exception,
                         IOException

Constructs a new AuthorizationData, instance.

Parameters:

der - 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

asn1Encode

public byte[] asn1Encode()
                  throws Asn1Exception,
                         IOException

Encodes an AuthorizationData object.

Returns:

byte array of encoded AuthorizationData 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 AuthorizationData parse(sun.security.util.DerInputStream data,
                                      byte explicitTag,
                                      boolean optional)
                               throws Asn1Exception,
                                      IOException

Parse (unmarshal) an AuthorizationData object from a DER input stream. This form of 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 AuthorizationData.

Throws:

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

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

writeAuth

public void writeAuth(CCacheOutputStream cos)
               throws IOException

Writes AuthorizationData data fields to a output stream.

Parameters:

cos - a CCacheOutputStream to be written to.

Throws:

IOException - if an I/O exception occurs.

toString

public String toString()

Overrides:

toString in class Object
