Constructor Detail

MIMEOutputStream

public MIMEOutputStream(OutputStream out)

Create an output stream that writes to the target output stream.

Parameters:

out - The wrapped output stream.

Method Detail

write

public void write(int ch)
           throws IOException

Specified by:

write in class OutputStream

Throws:

IOException

forceTerminatingLineBreak

public void forceTerminatingLineBreak()
                               throws IOException

Force the stream to be terminated at a line break. This is generally in preparation for the transport to write out an end-of-data marker, which generally needs to be preceded by a CRLF sequence.

Throws:

IOException

writeSMTPTerminator

public void writeSMTPTerminator()
                         throws IOException

Write out the SMTP terminator to the output stream. This ensures that we don't write out an extra CRLF if the data terminates with that value.

Throws:

IOException
