Detailed Description

a process that can be launched by a vtkMultiProcessController

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.

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();

virtual int vtkProcess::IsA ( const char *  name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

Reimplemented from vtkObject.

vtkProcess* vtkProcess::NewInstance

(

)

const

void vtkProcess::PrintSelf ( ostream &  os, vtkIndent  indent  )

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

virtual void vtkProcess::Execute ( )

pure virtual

Entry point of the process. This method is expected to update ReturnValue.

vtkMultiProcessController* vtkProcess::GetController

(

)

Give access to the controller that launched the process. Initial value is NULL.

void vtkProcess::SetController

(

vtkMultiProcessController *

aController

)

This method should not be called directly but set by the controller itself.

int vtkProcess::GetReturnValue

(

)

Value set at the end of a call to Execute.
