Detailed Description
A class for performing multithreaded execution.
- Date:

- Revision:
-
1.47
vtkMultithreader is a class that provides support for multithreaded execution using sproc() on an SGI, or pthread_create on any platform supporting POSIX threads. This class can be used to execute a single method on multiple threads, or to specify a method per thread.

[static] |
|
|
|
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkObject. |

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

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 vtkMultiThreader::SetNumberOfThreads |
( |
int |
|
) |
[virtual] |
|
|
|
Get/Set the number of threads to create. It will be clamped to the range 1 - VTK_MAX_THREADS, so the caller of this method should check that the requested number of threads was accepted. |
| virtual int vtkMultiThreader::GetNumberOfThreads |
( |

) |
[virtual] |
|
|
|
Get/Set the number of threads to create. It will be clamped to the range 1 - VTK_MAX_THREADS, so the caller of this method should check that the requested number of threads was accepted. |
| void vtkMultiThreader::SetGlobalMaximumNumberOfThreads |
( |
int |
val |
) |
[static] |
|
|
|
Set/Get the maximum number of threads to use when multithreading. This limits and overrides any other settings for multithreading. A value of zero indicates no limit. |
| int vtkMultiThreader::GetGlobalMaximumNumberOfThreads |
( |
|
) |
[static] |
|
|
|
Set/Get the maximum number of threads to use when multithreading. This limits and overrides any other settings for multithreading. A value of zero indicates no limit. |
| void vtkMultiThreader::SetGlobalDefaultNumberOfThreads |
( |
int |
val |
) |
[static] |
|
|
|
Set/Get the value which is used to initialize the NumberOfThreads in the constructor. Initially this default is set to the number of processors or VTK_MAX_THREADS (which ever is less). |

| void vtkMultiThreader::SingleMethodExecute |
( |
|
) |
|
|
|
|
Execute the SingleMethod (as define by SetSingleMethod) using this->NumberOfThreads threads. |
| void vtkMultiThreader::MultipleMethodExecute |
( |
|
) |
|
|
|
|
Execute the MultipleMethods (as define by calling SetMultipleMethod for each of the required this->NumberOfThreads methods) using this->NumberOfThreads threads. |
|
|
Set the SingleMethod to f() and the UserData field of the ThreadInfo that is passed to it will be data. This method (and all the methods passed to SetMultipleMethod) must be of type vtkThreadFunctionType and must take a single argument of type void *. |
|
|
Set the MultipleMethod at the given index to f() and the UserData field of the ThreadInfo that is passed to it will be data. |
|
|
Create a new thread for the given function. Return a thread id which is a number between 0 and VTK_MAX_THREADS - 1. This id should be used to kill the thread at a later time. |
| void vtkMultiThreader::TerminateThread |
( |
int |
thread_id |
) |
|
|
|
|
Terminate the thread that was created with a SpawnThreadExecute() |
