oracle.security.crypto.asn1
Class ASN1Set

java.lang.Object
oracle.security.crypto.asn1.ASN1Set

All Implemented Interfaces:

ASN1Constructed, ASN1Object, ASN1TaggedObject, Streamable

public class ASN1Set

extends java.lang.Object

implements ASN1TaggedObject, ASN1Constructed

An ASN.1 set.

The input may be any valid BER encoding of an ASN.1 set. The output is always a constructed, definite-length encoding of the set.

Field Summary

static int	BER An encoding type.
static int	DER_SET An encoding type.
static int	DER_SET_OF An encoding type.

Constructor Summary

ASN1Set()
Makes a new set with no elements.

ASN1Set(ASN1Object o)
Makes a set with one element.

ASN1Set(java.util.Enumeration e)

ASN1Set(java.io.InputStream is)

ASN1Set(java.util.Vector el)
Makes a set with the given elements.

Method Summary

void	addElement(ASN1Object o)
ASN1Object	elementAt(int n)
java.util.Vector	elements() Returns the components of this ASN.1 set, as a vector, each element of which is an instance of ASN1Object.
ASN1Object	firstElement()
int	getEncodingType()
ASN1Header	getHeader()
void	input(java.io.InputStream is) Inputs this object from the specified input stream.
ASN1Object	lastElement()
int	length() Length of this object's encoding.
void	output(java.io.OutputStream os) Outputs this object to the specified output stream.
void	setEncodingType(int encodingType) Sets the encoding type to one of BER, DER_SET or DER_SET_OF (default is DER_SET_OF).
int	size() Returns the number of components of this ASN.1 set.
java.lang.String	toString()
