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 }

public byte[] asn1Encode() throws Asn1Exception, IOException

Encodes an AuthorizationData object.

Returns:byte[]

byte array of encoded AuthorizationData object.

Exceptions
Asn1Exception:
if an error occurs while decoding an ASN1 encoded data.
IOException:
if an I/O error occurs while reading encoded data.
cloneback to summary
public Object clone()

Overrides java.lang.Object.clone.

Doc from java.lang.Object.clone.

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression: 

x.clone() != x
will be true, and that the expression: 
x.clone().getClass() == x.getClass()
will be true, but these are not absolute requirements. While it is typically the case that: 
x.clone().equals(x)
will be true, this is not an absolute requirement.

By convention, the returned object should be obtained by calling super.clone. If a class and all of its superclasses (except Object) obey this convention, it will be the case that x.clone().getClass() == x.getClass().

By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified.

public int count()

public AuthorizationDataEntry item(int i)
parseback to summary
public static AuthorizationData parse(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:DerInputStream

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

explicitTag:byte

tag number.

optional:boolean

indicates if this data field is optional

Returns:AuthorizationData

an instance of AuthorizationData.

Exceptions
Asn1Exception:
if an error occurs while decoding an ASN1 encoded data.
IOException:
if an I/O error occurs while reading encoded data.
toStringback to summary
public String toString()

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.

writeAuthback to summary
public void writeAuth(CCacheOutputStream cos) throws IOException

Writes AuthorizationData data fields to a output stream.

Parameters
cos:CCacheOutputStream

a CCacheOutputStream to be written to.

Exceptions
IOException:
if an I/O exception occurs.
