Constructor Detail

TraceInputStream

public TraceInputStream(InputStream in,
                        OutputStream traceStream,
                        boolean debug,
                        boolean encode)

Construct a debug trace stream.

Parameters:

in - The source input stream.

traceStream - The side trace stream to which trace data gets written.

encode - Indicates whether we wish the Trace data to be Q-P encoded.

Method Detail

setDebug

public void setDebug(boolean d)

Set the current setting of the debug trace stream debug flag.

Parameters:

d - The new debug flag settings.

read

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

Reads up to len bytes of data from this input stream, placing them directly into the provided byte array.

Overrides:

read in class FilterInputStream

Parameters:

b - the provided data buffer.

off - the starting offset within the buffer for placing the data.

len - the maximum number of bytes to read.

Returns:

that number of bytes that have been read and copied into the buffer or -1 if an end of stream occurs.

Throws:

IOException - for any I/O errors.

read

public int read()
         throws IOException

Read the next byte of data from the input stream, returning it as an int value. Returns -1 if the end of stream is detected.

Overrides:

read in class FilterInputStream

Returns:

The next byte of data or -1 to indicate end-of-stream.

Throws:

IOException - for any I/O errors
