Simple Data Logger

A simple data logger framwork

Prerequisites

• A compiler with c++11 support

Build

mkdir build
cd build
cmake ..
make

Usage

Create custom data type inheriting IDataObj and override the Dump method

class CustomeDataType : public IDataObj{
public:
    explicit CustomeDataType(int data) : some_data_(data) {
        if(!file_stream.is_open()){
            file_stream.open("./some_file.txt");
        }
    }

    inline void Dump() const override{
        if(file_stream.is_open()){
            file_stream << some_data_ << std::endl;
        }
    }

    static void CloseStream(){
        if(file_stream.is_open()){
            file_stream.close();
        }
    }
private:
    int some_data_;
    static std::ofstream file_stream;
};

Add shared pointer of the data instance to DataManager (Singleton)

DataManager::Instance().Add(std::make_shared<CustomeDataType>(1));

Then the data will be automatically dumped by calling the Dump method.

DataManger will use another thread to perform the dumping loop, control the loop rate by the following interface

DataManager::Instance().SetLoopSleepMs(50);
