C++ (Cpp) PRINT_AND_THROW Examples

Example #1

File: json_marshal.hpp Project: Hongxiao321321/trajopt-1

void fromJsonArray(const Json::Value& parent, std::vector<T>& ref, int size) {
  if (parent.size() != size) {
    PRINT_AND_THROW(boost::format("expected list of size size %i. got: %s\n")%size%parent);
  }
  else {
    fromJsonArray(parent, ref);
  }
}

Example #2

File: json_marshal.hpp Project: Hongxiao321321/trajopt-1

void childFromJson(const Json::Value& parent, T& ref, const char* name) {
  if (parent.isMember(name)) {
    const Json::Value& v = parent[name];
    fromJson(v, ref);
  }
  else {
    PRINT_AND_THROW(boost::format("missing field: %s")%name);
  }
}

Example #3
