Method Detail

copyStream

public static void copyStream(InputStream src,
                              OutputStream dest,
                              boolean closeStreams)
                       throws IOException,
                              NullArgumentException

Copy a stream.

Parameters:

src - the source input stream

dest - the destination output stream

closeStreams - TRUE if the streams should be closed on completion

Throws:

IOException - if an IO error occurs

NullArgumentException - if src or destination are null

copyStream

public static void copyStream(NetworkMonitor monitor,
                              URL source,
