Subject Re: Distribute closures error: "Operation cannot be performed in raw mode."
Date Thu, 02 Aug 2018 12:52:12 GMT
Here we go. Maybe the problem is the vector<std::string> inside the class
Calculation.

namespace ignite {
namespace binary {

template<>
struct BinaryType<Calculation>
{
   static int32_t GetTypeId()
   {
      return GetBinaryStringHashCode("Calculation");
   }

   static void GetTypeName(std::string& dst)
   {
      dst = "Calculation";
   }

   static int32_t GetFieldId(const char* name)
   {
      return GetBinaryStringHashCode(name);
   }

   static int32_t GetHashCode(const Calculation& obj)
   {
      return 0;
   }

   static bool IsNull(const Calculation& obj)
   {
      return false;
   }

   static void GetNull(Calculation& dst)
   {
      dst = Calculation();
   }

   static void Write(BinaryWriter& writer, const Calculation& obj)
   {
      writer.RawWriter().WriteBool(obj.local_log_);
      writer.RawWriter().WriteString(obj.service_name_);

      auto sa_writer = writer.WriteStringArray("input");
      for(const auto &s : obj.input_)
         sa_writer.Write(s);
      sa_writer.Close();
   }

   static void Read(BinaryReader& reader, Calculation& dst)
   {
      dst.local_log_ = reader.RawReader().ReadBool();
      dst.service_name_ = reader.RawReader().ReadString();

      auto sa_reader = reader.ReadStringArray("input");
      while(sa_reader.HasNext())
         dst.input_.push_back(sa_reader.GetNext());
   }
};

template<>
struct BinaryType<std::vector<std::string>>
{
   typedef std::vector<std::string> value_type;

   static int32_t GetTypeId()
   {
      return GetBinaryStringHashCode("VectorOfString");
   }

   static void GetTypeName(std::string& dst)
   {
      dst = "VectorOfString";
   }

   static int32_t GetFieldId(const char* name)
   {
      return GetBinaryStringHashCode(name);
   }

   static int32_t GetHashCode(const std::vector<std::string> &obj)
   {
      return 0;
   }

   static bool IsNull(const std::vector<std::string> &obj)
   {
      return !obj.size();
   }

   static void GetNull(std::vector<std::string> &dst)
   {
      dst = value_type();
   }

   static void Write(BinaryWriter &writer, const std::vector<std::string>
&obj)
   {
      auto sa_writer = writer.WriteStringArray("items");
      for(const auto &s : obj)
         sa_writer.Write(s);
      sa_writer.Close();
   }

   static void Read(BinaryReader &reader, std::vector<std::string> &dst)
   {
      auto sa_reader = reader.ReadStringArray("items");
      while(sa_reader.HasNext())
         dst.push_back(sa_reader.GetNext());
   }
};

} } // namespace ignite binary

Thanks,
   F.D.
