                       int length)
        Flushes the pending buffer into the given output array. If the output array is to small, only a partial flush is done.
        Parameters:
        output - the output array;
        offset - the offset into output array;
        length - the maximum number of bytes to store;
        Throws:
        java.lang.IndexOutOfBoundsException - if offset or length are invalid.

      • toByteArray

        public final byte[] toByteArray()
        Flushes the pending buffer and returns that data in a new array
        Parameters:
        output - the output stream
