      • readFully

        public static void readFully​(java.io.InputStream stream,
                             byte[] bytes,
                             int offset,
                             int length)
                      throws java.io.IOException
        Reads into a buffer from a stream, making multiple read calls if necessary.
        Parameters:
        stream - an InputStream to read from
        bytes - a buffer to write into
        offset - starting offset in the buffer for the data
        length - length of bytes to copy from the input stream to the buffer
        Throws:
        java.io.EOFException - if the end of the stream is reached before reading length bytes
        java.io.IOException - if there is an error while reading

      • writeFully

        public static void writeFully​(java.io.OutputStream outputStream,
                              java.nio.ByteBuffer buffer)
                       throws java.io.IOException
        Writes a buffer into a stream, making multiple write calls if necessary.
        Throws:
        java.io.IOException

      • readRemaining

        public static int readRemaining​(java.io.InputStream stream,
                                byte[] bytes,
                                int offset,
                                int length)
                         throws java.io.IOException
        Reads into a buffer from a stream, making multiple read calls if necessary returning the number of bytes read until end of stream.
        Parameters:
        stream - an InputStream to read from
        bytes - a buffer to write into
        offset - starting offset in the buffer for the data
        length - length of bytes to copy from the input stream to the buffer
        Returns:
        the number of bytes read
        Throws:
        java.io.IOException - if there is an error while reading
