Method Detail

write

public void write(int b)
           throws IOException

Overrides:

write in class CRLFOutputStream

Throws:

IOException

write

public void write(byte[] b,
                  int off,
                  int len)
           throws IOException

Overrides:

write in class CRLFOutputStream

Throws:

IOException

flush

public void flush()

Override flush method in FilterOutputStream. The MimeMessage writeTo method flushes its buffer at the end, but we don't want to flush data out to the socket until we've also written the terminating "\r\n.\r\n". We buffer nothing so there's nothing to flush. We depend on the fact that CRLFOutputStream also buffers nothing. SMTPTransport will manually flush the socket before reading the response.

Specified by:

flush in interface Flushable

Overrides:

flush in class FilterOutputStream

ensureAtBOL

public void ensureAtBOL()
                 throws IOException

Ensure we're at the beginning of a line. Write CRLF if not.

Throws:

IOException - if the write fails
