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

Constructor Detail

BERSequenceGenerator

public BERSequenceGenerator(java.io.OutputStream out)
                     throws java.io.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:

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

BERSequenceGenerator

public BERSequenceGenerator(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.

close

public void close()
           throws java.io.IOException

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

Throws:

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