Detailed Description

Classes for storing and manipulating the results of your analysis.

Create your own Result

In NAGASH, Result is the result of your job. And you can get it by

auto myresult = ResultGroupUser()->BookResult<ResultType>(name, filename, ...);

inside any class inherite from NAGASH::Job. The first argument is necessary, and the second argument is optional if no other arguments are needed.

If you want to define your own result, you should organize your code as :

#pragma once
 
class UserResult : public NAGASH::Result
{
    UserResult(std::shared_ptr<NAGASH::MSGTool> msg, std::shared_ptr<NAGASH::ConfigTool> config, const TString &name, const TString &filename, other arguments you want)
        : Result(msg, config, name, filename)
    {
        // do something you want
        // Then you can get this result by
        // ResultGroupUser()->BookResult<UserResult>(name, filename, other arguments);
        // inside class inherite from NAGASH::Job
    }
 
    // here are two functions you should override
    void Combine(std::shared_ptr<Result> result) override
    {
        // combine with other result
        auto subresult = std::dynamic_pointer_cast<std::remove_pointer<decltype(this)>::type>(result);
        if (subresult != nullptr)
        {
            // do something you want
        }
    }
 
    // this function is optional
    void WriteToFile() override
    {
    }
}
