Class: sun.security.krb5.internal.AuthorizationData

  • public class AuthorizationData
  • 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 }

  • clonetop

    public 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.

    The method clone for class Object performs a specific cloning operation. First, if the class of this object does not implement the interface Cloneable, then a CloneNotSupportedException is thrown. Note that all arrays are considered to implement the interface Cloneable. Otherwise, this method creates a new instance of the class of this object and initializes all its fields with exactly the contents of the corresponding fields of this object, as if by assignment; the contents of the fields are not themselves cloned. Thus, this method performs a "shallow copy" of this object, not a "deep copy" operation.

    The class Object does not itself implement the interface Cloneable, so calling the clone method on an object whose class is Object will result in throwing an exception at run time.

    Return:
    @return a clone of this instance.
    Override hierarchy:
    clone from Object

  • parsetop

    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:
    @param data the Der input stream value, which contains one or more marshaled value.
    @param explicitTag tag number.
    @param optional indicates if this data field is optional
    Return:
    @return an instance of AuthorizationData.
    Exceptions:
    @exception Asn1Exception if an error occurs while decoding an ASN1 encoded data.
    @exception IOException if an I/O error occurs while reading encoded data.

  • toStringtop

    public String toString()
    Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

    The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of: 

     getClass().getName() + '@' + Integer.toHexString(hashCode())
    Return:
    @return a string representation of the object.

    toString from Object

  • writeAuthtop

    public void writeAuth(CCacheOutputStream cos) throws IOException
    Writes AuthorizationData data fields to a output stream.
    Parameters:
    @param cos a CCacheOutputStream to be written to.
    Exceptions:
    @exception IOException if an I/O exception occurs.
