Detailed Description

Critical section locking class.

vtkCriticalSection allows the locking of variables which are accessed through different threads. This header file also defines vtkSimpleCriticalSection which is not a subclass of vtkObject. The API is identical to that of vtkMutexLock, and the behavior is identical as well, except on Windows 9x/NT platforms. The only difference on these platforms is that vtkMutexLock is more flexible, in that it works across processes as well as across threads, but also costs more, in that it evokes a 600-cycle x86 ring transition. The vtkCriticalSection provides a higher-performance equivalent (on Windows) but won't work across processes. Since it is unclear how, in vtk, an object at the vtk level can be shared across processes in the first place, one should use vtkCriticalSection unless one has a very good reason to use vtkMutexLock. If higher-performance equivalents for non-Windows platforms (Irix, SunOS, etc) are discovered, they should replace the implementations in this class
