Constructor Summary

Constructors

Constructor	Description
BERSequenceGenerator(OutputStream out)	Use the passed in stream as the target for the generator, writing out the header tag for a constructed SEQUENCE.
BERSequenceGenerator(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

Modifier and Type	Method	Description
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 BER end tag.

Constructor Details

BERSequenceGenerator

public BERSequenceGenerator(OutputStream out)
                     throws IOException

Use the passed in stream as the target for the generator, writing out the header tag for a constructed SEQUENCE.

Parameters:

out - target stream

Throws:

IOException - if the target stream cannot be written to.

BERSequenceGenerator

public BERSequenceGenerator(OutputStream out,
 int tagNo,
 boolean isExplicit)
                     throws 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:

IOException - if the target stream cannot be written to.

Method Details

addObject

public void addObject(ASN1Encodable object)
               throws IOException

Add an object to the SEQUENCE being generated.

Parameters:

object - an ASN.1 encodable object to add.

Throws:

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

addObject

public void addObject(ASN1Primitive primitive)
               throws IOException

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

Parameters:

primitive - an ASN.1 primitive to add.

Throws:

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

close

public void close()
           throws IOException

Close of the generator, writing out the BER end tag.

Throws:

IOException - if the target stream cannot be written.
