        public ByteArrayIOHandler​(byte[] byteArray)
    • Method Detail

      • toByteArray

        public byte[] toByteArray()
      • read

        public void read​(DataContext context,
                         byte[] data,
                         long position)
                  throws IOException
        Description copied from interface: IOHandler
        Reads a sequence of up to data.length bytes into the given array starting from the the given position. If the position is greater than the file's current size then no bytes are read.

        A read operation might not fill the array, and in fact it might not read any bytes at all. Whether or not it does so, depends upon the state of the file, e.g. only bytes that remain in the file starting from the given position will be read.

        Specified by:
        read in interface IOHandler
        Parameters:
        context - The I/O context.
        data - The data array into which bytes are to be transferred.
        position - The file position at which the transfer is to begin; must be non-negative.
        Throws:
        IOException - If an I/O error occurs.
      • write

        public void write​(DataContext context,
                          byte[] data,
                          long position)
                   throws IOException
        Description copied from interface: IOHandler
        Writes a sequence of up to data.length bytes to the file, starting at the given position. If the given position is greater than the file's current size then the file will be grown to accommodate the new bytes; the values of any bytes between the previous end-of-file and the newly-written bytes are unspecified.
        Specified by:
        write in interface IOHandler
        Parameters:
        context - The I/O context.
        data - The data array from which bytes are to be transferred.
        position - The file position at which the transfer is to begin; must be non-negative.
        Throws:
        IOException - If an I/O error occurs.
      • getMaxPosition

        public long getMaxPosition()
        Description copied from interface: IOHandler
        Returns the current size of the backing file, array or stream.

        This value may change, while writing to a growing file or array. If the value is unknown -1 will be returned.

        Specified by:
        getMaxPosition in interface IOHandler
        Returns:
        Te maximum position.
