protected CMSOutputStream(OutputStream out, int contentType, boolean dataOut, boolean outer)
out - The output stream to use.contentType - The content type of the output from CMSContentTypes.dataOut - Determines whether or not to write the data to the output stream. It is not writtten
out in a clear signed SMIME message.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 |
public void close()
throws IOException
OutputStreamclose
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.
close in class OutputStream
OutputStreamIOException - if an I/O error occurs.
public void flush()
throws IOException
OutputStreamflush is
that calling it is an indication that, if any bytes previously
written have been buffered by the implementation of the output
stream, such bytes should immediately be written to their
intended destination.
The flush method of OutputStream does nothing.
flush in class OutputStream
OutputStreamIOException - if an I/O error occurs.
public void write(byte[] data)
throws IOException
OutputStreamb.length bytes from the specified byte array
to this output stream. The general contract for write(b)
is that it should have exactly the same effect as the call
write(b, 0, b.length).write in class OutputStream
OutputStreamb - the data.IOException - if an I/O error occurs.OutputStream.write(byte[], int, int)
public abstract void write(byte[] data,
int offset,
int length)
throws IOException
OutputStreamlen 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.
write in class OutputStream
OutputStreamb - the data.off - the start offset in the data.len - the number of bytes to write.IOException - if an I/O error occurs. In particular,
an IOException is thrown if the output
stream is closed.
public void write(int data)
throws IOException
OutputStreamwrite is that one byte is written
to the output stream. The byte to be written is the eight
low-order bits of the argument b. The 24
high-order bits of b are ignored.
Subclasses of OutputStream must provide an
implementation for this method.
write in class OutputStream
OutputStreamb - the byte.IOException - if an I/O error occurs. In particular,
an IOException may be thrown if the
output stream has been closed.
