deserializePayload method

@override int deserializePayload(SonarDataBuilder builder, ByteData byteData, Endian endianness, int offset,)

Call to deserialize only the payload, no header. The Builder is to allow passing the message to build into. returns a int with a serialized size

Implementation

@override

    Endian endianness, int offset) {
  var byteOffset = offset;

  // field type
  builder.type = imc.SonarDataEnumType(byteData.getUint8(byteOffset));

  // field frequency
  builder.frequency = byteData.getUint32(byteOffset, endianness);
  byteOffset += 4;
  // field minRange
  builder.minRange = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  // field maxRange
  builder.maxRange = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  // field bitsPerPoint
  builder.bitsPerPoint = byteData.getUint8(byteOffset);
  byteOffset += 1;
  // field scaleFactor
  builder.scaleFactor = byteData.getFloat32(byteOffset, endianness);
  byteOffset += 4;
  // field beamConfig
  var beamConfigMMsgsNumber = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
