Constructor Detail

LogInputStream

public LogInputStream(java.io.InputStream is,
                      java.io.PrintStream ps)
This class can be used to keep a copy of the bytes read from the supplied InputStream

Parameters:
is - The InputStream to read from
ps - the PrintStream to write any bytes read to. We use a PrintStream so that we don't have to worry about any Exceptions on the OutputStream
Method Detail

read

public int read()
         throws java.io.IOException
Reads the next byte of data from this input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

This method simply performs in.read() and returns the result.

Overrides:
read in class java.io.FilterInputStream
Returns:
the next byte of data, or -1 if the end of the stream is reached.
Throws:
java.io.IOException - if an I/O error occurs.

FilterInputStream.in

read

public int read(byte[] b,
                int off,
                int len)
         throws java.io.IOException
Reads up to len bytes of data from this input stream into an array of bytes. This method blocks until some input is available.

This method simply performs in.read(b, off, len) and returns the result.

Overrides:
read in class java.io.FilterInputStream
Parameters:
b - the buffer into which the data is read.
off - the start offset of the data.
len - the maximum number of bytes read.
Returns:
the total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached.
Throws:
java.io.IOException - if an I/O error occurs.
See Also:
FilterInputStream.in

markSupported

public boolean markSupported()
Tests if this input stream supports the mark and reset methods. This method always returns false, as we are not able to reset the PrintStream in an appropriate manner

Overrides:
markSupported in class java.io.FilterInputStream
Returns:
false
