ParallelForWithPreWork(int32, TFunctionRef< void(int32)>, TFunctionRef< void()>, EParallelForFlags)
Description
General purpose parallel for that uses the taskgraph
| Name | ParallelForWithPreWork |
| Type | function |
| Header File | /Engine/Source/Runtime/Core/Public/Async/ParallelFor.h |
| Include Path | #include "Async/ParallelFor.h" |
void ParallelForWithPreWork
(
int32 Num,
TFunctionRef < void> Body,
TFunctionRef < void> CurrentThreadWorkToDoBeforeHelping,
EParallelForFlags Flags
)
Parameters
| Name | Remarks |
|---|---|
| Num; | number of calls of Body; Body(0), Body(1)....Body(Num - 1) |
| Body; | Function to call from multiple threads |
| CurrentThreadWorkToDoBeforeHelping; | The work is performed on the main thread before it starts helping with the ParallelFor proper |
| Flags; | Used to customize the behavior of the ParallelFor if needed. Notes: Please add stats around to calls to parallel for and within your lambda as appropriate. Do not clog the task graph with long running tasks or tasks that block. |

Parameters
| Name | Remarks |
|---|---|
| Num; | number of calls of Body; Body(0), Body(1)....Body(Num - 1) |
| Body; | Function to call from multiple threads |
| CurrentThreadWorkToDoBeforeHelping; | The work is performed on the main thread before it starts helping with the ParallelFor proper |
| bForceSingleThread; | Mostly used for testing, if true, run single threaded instead. Notes: Please add stats around to calls to parallel for and within your lambda as appropriate. Do not clog the task graph with long running tasks or tasks that block. |
