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.

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.
