Constructor Detail

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.
out - the trace stream
Method Detail

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
