Constructor Detail

CMSSignedReceiptOutputStream

public CMSSignedReceiptOutputStream(CMSSignedDataOutputStream output,
                                    OID messageContentType,
                                    byte[] signedContentIdentifier,
                                    byte[] signatureValue)

Creates a CMSSignedReceiptOutputStream. Note that a signed receipt can only be inside of a signed message, hence the only output stream allowed, for this to write too, is a CMSSignedDataOutputStream.

Parameters:

output - The CMSSignedDataOutputStream to write the signed receipt to.

messageContentType - An OID representing the content type of the original message this receipt covers.

signedContentIdentifier - The signed content identifier of the receipt, from the receipt request.

signatureValue - The encoding of the signature from the orignal message this receipt covers. Note that no encoding is done to this value before it is written to the stream. It is assumed that signatureValue is already encoded as an OCTET STRING.

Method Detail

write

public void write(byte[] data,
                  int offset,
                  int length)
           throws IOException

Description copied from class: OutputStream

Writes len bytes from the specified byte array starting at offset off to this output stream. The general contract for write(b, off, len) is that some of the bytes in the array b are written to the output stream in order; element b[off] is the first byte written and b[off+len-1] is the last byte written by this operation.

The write method of OutputStream calls the write method of one argument on each of the bytes to be written out. Subclasses are encouraged to override this method and provide a more efficient implementation.

If b is null, a NullPointerException is thrown.

If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown.

Specified by:

write in class CMSOutputStream

Parameters:

data - the data.

offset - the start offset in the data.

length - the number of bytes to write.

Throws:

IOException - if an I/O error occurs. In particular, an IOException is thrown if the output stream is closed.

close

public void close()
           throws IOException

Description copied from class: OutputStream

Closes this output stream and releases any system resources associated with this stream. The general contract of close is that it closes the output stream. A closed stream cannot perform output operations and cannot be reopened.

The close method of OutputStream does nothing.

Overrides:

close in class CMSOutputStream

Throws:

IOException - if an I/O error occurs.
