## Detailed Description

Class in charge of generating the C code of a TPGGraph.

Each program of the TPGGraph is represented by a C function. All the functions are regrouped in a file. Another file holds the required functions to iterate through the TPGGraph.

To use the generated code two code templates are provided in the directory doc/codeGen. One template is for generic learning environment. The other one is dedicated for adversarial learning environment and manages the switch between the players. Both templates can use the inference with the codeGen or the inference with Gegelati.

The repo gegelati apps give some example of the template code completed for TicTacToe, Pendulum and StickGame.

## ◆ ~TPGGenerationEngine()

CodeGen::TPGGenerationEngine::~TPGGenerationEngine | ( |  | ) |
| virtual

destructor of the class.

add endif at the end of the header and close both file.

## Member Function Documentation

## ◆ generateAction()

virtual void CodeGen::TPGGenerationEngine::generateAction | ( | const TPG::TPGAction & | action | ) |
| protectedpure virtual

Method for generating a action of the graph.

This method generates the C function that represents an action. The generated function return a NULL pointer and write the action in the pointer given as parameter.

Parameters

  [in] | action | const reference of the TPGAction that must be generated.

Implemented in CodeGen::TPGStackGenerationEngine, and CodeGen::TPGSwitchGenerationEngine.

## ◆ generateEdge()

virtual void CodeGen::TPGGenerationEngine::generateEdge | ( | const TPG::TPGEdge & | edge | ) |
| protectedpure virtual

Method for generating the code for an edge of the graph.

This function generates the code that represents an edge. An edge of a team is represented by a struct with: an integer, a function pointer of type : double (ptr_prog)() for the program of the edge a a function pointer of type : void (ptr_vertex)(int) to represent the destination of the edge

Parameters

  [in] | edge | that must be generated.

Implemented in CodeGen::TPGStackGenerationEngine, and CodeGen::TPGSwitchGenerationEngine.

## ◆ generateTeam()

virtual void CodeGen::TPGGenerationEngine::generateTeam | ( | const TPG::TPGTeam & | team | ) |
| protectedpure virtual

Method for generating the code for a team of the graph.

This method generates the C function that represents a team. Each function representing a team contains a static array of TPGEdge and calls the function executeTeam(Edge*, int).

Parameters

  [in] | team | const reference of the TPGTeam that must be generated.

Implemented in CodeGen::TPGStackGenerationEngine, and CodeGen::TPGSwitchGenerationEngine.

## ◆ generateTPGGraph()

virtual void CodeGen::TPGGenerationEngine::generateTPGGraph | ( |  | ) |
| pure virtual

function that creates the C files required to execute the TPG without gegelati.

This function iterates trough the TPGGraph and create the required C code to represent each element of the TPGGraph.

Implemented in CodeGen::TPGStackGenerationEngine, and CodeGen::TPGSwitchGenerationEngine.

## ◆ initHeaderFile()

virtual void CodeGen::TPGGenerationEngine::initHeaderFile | ( |  | ) |
| protectedpure virtual

function printing generic code declaration in the main file header.

This function print the the struct required to represent the TPG and the prototypes of the function to execute the TPG and manage the stack of visited edges.

Implemented in CodeGen::TPGStackGenerationEngine, and CodeGen::TPGSwitchGenerationEngine.

## ◆ initTpgFile()

virtual void CodeGen::TPGGenerationEngine::initTpgFile | ( |  | ) |
| protectedpure virtual

function printing generic code in the main file.

This function prints generic code to execute the TPG and manage the stack of visited edges.

Implemented in CodeGen::TPGStackGenerationEngine, and CodeGen::TPGSwitchGenerationEngine.

## Member Data Documentation

## ◆ filenameProg

const std::string CodeGen::TPGGenerationEngine::filenameProg = "program"
| inlinestaticprotected

String added at the end of the parameter filename to create the filename of the file with the programs of the TPGGraph.

## ◆ progGenerationEngine

CodeGen::ProgramGenerationEngine CodeGen::TPGGenerationEngine::progGenerationEngine
| protected

ProgramGenerationEngine for generating Programs of edges.

Keeping this ProgramGenerationEngine as an attribute avoids wasting time rebuilding a new one for each edge.
