    • MutableModbusDataView

      public MutableModbusDataView(net.solarnetwork.util.IntShortMap dataRegisters)
      Construct with data registers to mutate.
      Parameters:
      dataRegisters - the registers to mutate; calling code should by synchronized on this instance

    • saveDataMap

      public final void saveDataMap(Map<Integer,? extends Number> data)
      Description copied from interface: ModbusData.MutableModbusData
      Store a mapping of addresses to associated 16-bit integer register data values.
      Specified by:
      saveDataMap in interface ModbusData.MutableModbusData
      Parameters:
      data - the data map to save; all values will be treated as 16-bit integer

    • saveDataArray

      public final void saveDataArray(short[] data, int addr)
      Description copied from interface: ModbusData.MutableModbusData
      Store an array of 16-bit integer register data values, starting at a given address.
      Specified by:
      saveDataArray in interface ModbusData.MutableModbusData
      Parameters:
      data - the data array to save, as shorts
      addr - the starting address of the data

    • saveDataArray

      public final void saveDataArray(int[] data, int addr)
      Description copied from interface: ModbusData.MutableModbusData
      Store an array of 16-bit integer register data values, starting at a given address.

      Note that the data values will be treated as 16-bit unsigned values.

      Specified by:
      saveDataArray in interface ModbusData.MutableModbusData
      Parameters:
      data - the data array to save, as ints
      addr - the starting address of the data

    • saveDataArray

      public final void saveDataArray(Integer[] data, int addr)
      Description copied from interface: ModbusData.MutableModbusData
      Store an array of 16-bit integer register data values, starting at a given address.

      Note that the data values will be treated as 16-bit unsigned values.

      Specified by:
      saveDataArray in interface ModbusData.MutableModbusData
      Parameters:
      data - the data array to save, as ints
      addr - the starting address of the data

    • saveBytes

      public void saveBytes(byte[] data, int addr)
      Description copied from interface: ModbusData.MutableModbusData
      Store an array of bytes into 16-bit register data values, starting at a given address.

      The bytes are packed into 16-bit values, so the number of register addresses written to will be half of the length of bytes (rounded up to nearest even even length).

      This method will assume ModbusWordOrder.MostToLeastSignificant word ordering.

      Specified by:
      saveBytes in interface ModbusData.MutableModbusData
      Parameters:
      data - the bytes to save
      addr - the starting address of the data
