public final class CMSDataOutputStream
extends CMSOutputStream

Implements a CMS data output stream so that outgoing data can be written to the output stream.

Constructor Detail

CMSDataOutputStream

public CMSDataOutputStream(OutputStream out,
                           boolean outer)
Creates a data output stream.

Parameters:
out - The outputstream to write data too.
outer - A boolean to determine if this is the outer CMS stream, since CMS streams can be nested within themselves. The stream needs to know if it is the "outer" layer so it can do some extra processing. For example, if you wish to sign and then encrypt a message, the CMSSignedDataOutputStream will be the "outer" layer.

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.

Overrides:
write in class CMSOutputStream

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
