Constructor Detail

TraceOutputStream

public TraceOutputStream(OutputStream out,
                         MailLogger logger)

Creates an output stream filter built on top of the specified underlying output stream.

Parameters:

out - the underlying output stream.

logger - log trace here

TraceOutputStream

public TraceOutputStream(OutputStream out,
                         OutputStream traceOut)

Creates an output stream filter built on top of the specified underlying output stream.

Parameters:

out - the underlying output stream.

traceOut - the trace stream.

Method Detail

setTrace

public void setTrace(boolean trace)

Set the trace mode.

Parameters:

trace - the trace mode

setQuote

public void setQuote(boolean quote)

Set quote mode.

Parameters:

quote - the quote mode

write

public void write(int b)
           throws IOException

Writes the specified byte to this output stream. Writes out the byte into the trace stream if the trace mode is true

Overrides:

write in class FilterOutputStream

Parameters:

b - the byte to write

Throws:

IOException - for I/O errors

write

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

Writes b.length bytes to this output stream. Writes out the bytes into the trace stream if the trace mode is true

Overrides:

write in class FilterOutputStream

Parameters:

b - bytes to write

off - offset in array

len - number of bytes to write

Throws:

IOException - for I/O errors
