public class DERSequenceGenerator

extends DERGenerator

A stream generator for DER SEQUENCEs

Field Summary

Fields inherited from class org.bouncycastle.asn1.ASN1Generator

_out

Constructor Summary

DERSequenceGenerator(java.io.OutputStream out)
Use the passed in stream as the target for the generator.

DERSequenceGenerator(java.io.OutputStream out, int tagNo, boolean isExplicit)
Use the passed in stream as the target for the generator, writing out the header tag for a tagged constructed SEQUENCE (possibly implicit).

Method Summary

void	addObject(ASN1Encodable object) Add an object to the SEQUENCE being generated.
void	addObject(ASN1Primitive primitive) Add an ASN1.1 primitive to the SEQUENCE being generated.
void	close() Close of the generator, writing out the SEQUENCE.
java.io.OutputStream	getRawOutputStream() Return the target stream for the SEQUENCE.

Constructor Detail

DERSequenceGenerator

public DERSequenceGenerator(java.io.OutputStream out)
                     throws java.io.IOException

Use the passed in stream as the target for the generator.

Parameters:

out - target stream

Throws:

java.io.IOException - if the target stream cannot be written to.

DERSequenceGenerator

public DERSequenceGenerator(java.io.OutputStream out,
                            int tagNo,
                            boolean isExplicit)
                     throws java.io.IOException

Use the passed in stream as the target for the generator, writing out the header tag for a tagged constructed SEQUENCE (possibly implicit).

Parameters:

out - target stream

tagNo - the tag number to introduce

isExplicit - true if this is an explicitly tagged object, false otherwise.

Throws:

java.io.IOException - if the target stream cannot be written to.

Method Detail

addObject

public void addObject(ASN1Encodable object)
               throws java.io.IOException

Add an object to the SEQUENCE being generated.

Parameters:

object - an ASN.1 encodable object to add.

Throws:

java.io.IOException - if the target stream cannot be written to or the object cannot be encoded.

addObject

public void addObject(ASN1Primitive primitive)
               throws java.io.IOException

Add an ASN1.1 primitive to the SEQUENCE being generated.

Parameters:

primitive - an ASN.1 primitive to add.

Throws:

java.io.IOException - if the target stream cannot be written to or the primitive cannot be encoded.

getRawOutputStream

public java.io.OutputStream getRawOutputStream()

Return the target stream for the SEQUENCE.

Specified by:

getRawOutputStream in class ASN1Generator

Returns:

the OutputStream the SEQUENCE is being written to.

close

public void close()
           throws java.io.IOException

Close of the generator, writing out the SEQUENCE.

Throws:

java.io.IOException - if the target stream cannot be written.
