active-class

A C++17 implementation of an active class: an active class generates a thread and controls it using functional objects passed by the client application

Requirements

cmake is used to compile the sources.

The default compiler used is clang++-5.0.

The cmake files compile with -std=c++17.

The unit tests are implemented in googletest: be sure you have installed googletest to compile.

Install and Run Unit Tests

$ git clone https://github.com:massimo-marino/active-class.git
$ cd active-class
$ mkdir build
$ cd build
$ cmake ..
$ make
$ cd src/unitTests
$ ./unitTests

The unit tests provide examples of usage of active classes.

The Active Class

The active class generates a thread whose function runs a sequence of three client provided functional objects:

• a prologue
• a body
• an epilogue

All the above functional objects are unary functions whose unique argument is a data structure provided by the calling application.

The prologue and the epilogue return a bool, the body returns a client defined type.

The thread runs as follows:

bool epilogueResult{};
bool prologueResult = prologue(threadData);
if ( false == prologueResult )
{
  body(threadData);
  epilogueResult = epilogue(threadData);
}

See the class activeClass and its method void activeClassBody() for the details.

The unit tests named runThreadOK_1, runThreadOK_2, and runThreadOK_3 provide examples of usage of the active class concept.
