Method Details

registersToValue

protected final T registersToValue(com.ghgande.j2mod.modbus.procimg.Register[] registers)

Description copied from class: ModbusRegisterElement

Converts the Registers from j2mod to the expected type.

The length of the registers array is guaranteed to match `this.length`.

Specified by:

registersToValue in class ModbusRegisterElement<SELF extends AbstractModbusElement<SELF,com.ghgande.j2mod.modbus.procimg.Register[],T>,T>

Parameters:

registers - the Registers

Returns:

the typed/converted value

valueToRaw

protected com.ghgande.j2mod.modbus.procimg.Register[] valueToRaw(T value)

Specified by:

valueToRaw in class AbstractModbusElement<SELF extends AbstractModbusElement<SELF,com.ghgande.j2mod.modbus.procimg.Register[],T>,com.ghgande.j2mod.modbus.procimg.Register[],T>
