public static long copy(InputStream inputStream, OutputStream outputStream, boolean closeOutputStream) throws IOException
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
