oracle.security.crypto.asn1
Class ASN1Sequence

java.lang.Object
oracle.security.crypto.asn1.ASN1Sequence

All Implemented Interfaces:

ASN1Constructed, ASN1Object, ASN1TaggedObject, Streamable

public class ASN1Sequence

extends java.lang.Object

implements ASN1TaggedObject, ASN1Constructed

An ASN.1 sequence.

The input may be any valid BER encoding of an ASN.1 sequence. The output is always a constructed, definite-length encoding of the sequence, and will be a DER encoding if and only if the output of every component is a DER encoding (provided DER requirements with respect to default components are obeyed).

Constructor Summary

ASN1Sequence()
Makes a sequence with no components.

ASN1Sequence(ASN1Object o)
Makes a sequence with one component.

ASN1Sequence(java.util.Collection<? extends ASN1Object> el)
Makes a sequence with the given components.

ASN1Sequence(java.io.InputStream is)

ASN1Sequence(java.util.List<? extends ASN1Object> el)

ASN1Sequence(java.util.Vector<? extends ASN1Object> el)
Deprecated. use ASN1Sequence(List)

Method Summary

void	addElement(ASN1Object o)
ASN1Object	elementAt(int n)
java.util.Vector<ASN1Object>	elements() Deprecated. use elementsAsList()
java.util.ArrayList<ASN1Object>	elementsAsList() Returns the components of this ASN.1 sequence, as a list, each element of which is an instance of ASN1Object.
ASN1Object	firstElement()
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.
static ASN1Header	makeHeader(int len)
void	output(java.io.OutputStream os) Outputs this object to the specified output stream.
int	size() Returns the number of components of this ASN.1 sequence.
java.lang.String	toString()
