copyStream	back to summary
public static int copyStream(InputStream input, ByteBuffer output, byte[] buffer) throws IOException Copy the data from an `InputStream` to a `ByteBuffer`, using the specified byte[] as a temporary buffer. The buffer's limit is increased by the number of bytes copied, the position is left unchanged. The stream is not closed. Parameters output:ByteBuffer Must be a direct Buffer with native byte order and the buffer MUST be large enough to hold all the bytes in the stream. No error checking is performed. Returns:int the number of bytes copied.
