InputStream
to the given OutputStream. Shortcut for
copy(pInputStream, pOutputStream, new byte[8192]);
inputStream - The input stream, which is being read.
It is guaranteed, that InputStream.close() is called
on the stream.outputStream - The output stream, to which data should
be written. May be null, in which case the input streams
contents are simply discarded.closeOutputStream - True guarantees, that OutputStream.close()
is called on the stream. False indicates, that only
OutputStream.flush() should be called finally.java.io.IOException - An I/O error occurred.public static long copy(java.io.InputStream inputStream,
