This is a sample C++ project for "Pipes and Filters" architecture in Software Engineering.
- Pipes: Simply send data from filter to filter. Pipes are independent to types of filter they are connected to. Pipes can be connected to multiple filters.
- Filters: Process some kind of data got from input pipe and output the data through output pipe. Filters do not know about previous filters nor the next filters.
For simplicity, I only used pipes that pass through vector<string>s.
From IPipe interface, all pipes should implement these two methods. PutData() sends data into the pipe, GetData() is the data that came out from the pipe.
From IFilter interface, all fiters should implement Process() method(member function) so that the filter can process input data from the input pipe and then feed the processed data into the output pipe.
I think real world example is way different from this, but this sample project explains the concept of this architecture well enough.
CMake version 3.26 above required.
git clone <this_repo>
cd <this_repo>
mkdir build
cd build
cmake ..
For GCC/Clang... users can use make command to build after cmake ..
For Windows MSVC users, the command above will create .sln file so you can use that for building instead. (Open with Visual Studio IDE)
./cxx-pipe-and-filter {textfile.txt}
For default, the program will print words per line, and total words in the text file. Sample lorem ipsum text is in /src/file.txt. CMake will copy to build directory when building the project.
In main.cpp, you can edit the filters, pipes or even implement your own types in Filter.hpp/Pipe.hpp.
