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.IOException - An I/O error occurred.public static long copy(InputStream inputStream, OutputStream outputStream, boolean closeOutputStream, byte[] buffer) throws IOException
