// .NAME vtkProcess - a process that can be launched by a vtkMultiProcessController
// .SECTION Description
// vtkProcess is an abstract class representing a process that can be launched
// by a vtkMultiProcessController. Concrete classes just have to implement
// Execute() method and make sure it set the proper value in ReturnValue.
//
// .SECTION Example
// class MyProcess: public vtkProcess
// ...
// vtkMultiProcessController *c;
// MyProcess *p=new MyProcess::New();
// p->SetArgs(argc,argv); // some parameters specific to the process
// p->SetX(10.0); // ...
// c->SetSingleProcess(p);
// c->SingleMethodExecute();
// int returnValue=p->GetReturnValue();
//
// .SECTION see also
// vtkMultiProcessController
#ifndef vtkProcess_h
#define vtkProcess_h
#include "vtkParallelCoreModule.h" // For export macro
#include "vtkObject.h"
class vtkMultiProcessController;
class VTKPARALLELCORE_EXPORT vtkProcess : public vtkObject
{
public:
vtkTypeMacro(vtkProcess,vtkObject);
void PrintSelf(ostream& os, vtkIndent indent);
// Description
// Entry point of the process.
// This method is expected to update ReturnValue.
virtual void Execute()=0;
// Description:
// Give access to the controller that launched the process.
// Initial value is NULL.
vtkMultiProcessController *GetController();
// Description:
// This method should not be called directly but set by the controller
// itself.
void SetController(vtkMultiProcessController *aController);
// Description:
// Value set at the end of a call to Execute.
int GetReturnValue();
protected:
