Constructor Details

TraceInputStream

public TraceInputStream(InputStream in,
 MailLogger logger)

Creates an input stream filter built on top of the specified input stream.

Parameters:

in - the underlying input stream.

logger - log trace here

TraceInputStream

public TraceInputStream(InputStream in,
 OutputStream traceOut)

Creates an input stream filter built on top of the specified input stream.

Parameters:

in - the underlying input stream.

traceOut - the trace stream.

Method Details

setTrace

public void setTrace(boolean trace)

Set trace mode.

Parameters:

trace - the trace mode

setQuote

public void setQuote(boolean quote)

Set quote mode.

Parameters:

quote - the quote mode

read

public int read()
         throws IOException

Reads the next byte of data from this input stream. Returns -1 if no data is available. Writes out the read byte into the trace stream, if trace mode is true

Overrides:

read in class FilterInputStream

Throws:

IOException

read

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

Reads up to len bytes of data from this input stream into an array of bytes. Returns -1 if no more data is available. Writes out the read bytes into the trace stream, if trace mode is true

Overrides:

read in class FilterInputStream

Throws:

IOException
