Syntax
class FGPUSortManager : public FRefCountedObject
Remarks
A manager that handles different GPU sort tasks. Each task has different constraints about when the data can be generated and when the sorted results need to be available. The usecase involes registering a sort task through AddTask() and then initializing the sort data through the KeyGen callback. The sort manager can be enabled or disabled through "fx.AllowGPUSorting"
