 int length)

Method Details

byteBufferToValue

protected abstract T byteBufferToValue(ByteBuffer buff)

valueToByteBuffer

protected abstract void valueToByteBuffer(ByteBuffer buff,
 T value)

byteOrder

public final SELF byteOrder(ByteOrder byteOrder)

Sets the Byte-Order. Default is "BIG_ENDIAN". See http://www.simplymodbus.ca/FAQ.htm#Order.

Parameters:

byteOrder - the ByteOrder

Returns:

myself

getByteOrder

protected final ByteOrder getByteOrder()

valueToRaw

protected final com.ghgande.j2mod.modbus.procimg.Register[] valueToRaw(T value,
 WordOrder wordOrder)

rawToValue

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

Description copied from class: AbstractModbusElement

Converts the RAW value from j2mod to the expected type.

Specified by:

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

Parameters:

registers - the raw value

Returns:

the typed/converted value

registersToValue

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

Converts the Registers from j2mod to the expected type.

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

Parameters:

registers - the Registers

Returns:

the typed/converted value

commonRegistersToValue

protected final T commonRegistersToValue(com.ghgande.j2mod.modbus.procimg.Register[] registers,
 WordOrder wordOrder)
