ThreadedCalculationForTParameter1, TParameter2 Method (Int32, Int32, TParameter1, TParameter2, ITrackCalculationProgress, ThreadedCalculationBodyCallbackWithProgress2TParameter1, TParameter2)

A 'for' loop that is parallelized among multiple threads according to the ThreadingPolicy active in the calling thread. The loop behaves as if written as for (int i = start; i < stop; ++i). Inside the body callback, the ThreadingPolicy will be configured to use only the calling thread for any further parallelizable operations. This usually improves performance by putting the parallelism where it is most useful: in the 'for' loop itself. However, if you do wish to parallelize operations invoked inside the 'for' loop, you must explicitly set the ThreadingPolicy inside the callback.

The body of the 'for' loop is given an ITrackCalculationProgress instance that can be used to report detailed information about the progress of individual loop iterations. It is not recommended to use this overload when looping through a large number of iterations or when detailed information about the progress of individual iterations is not required, because there is some overhead to the detailed progress reporting.

Parameters

start: Type: SystemInt32
The start of the loop.
stop: Type: SystemInt32
The end of the loop. The body is NOT executed for this value.
parameter1: Type: TParameter1
The first parameter that is passed to the body of the loop. If this instance implements IThreadAware and IsThreadSafe returns , a copy of the parameter is made for each thread using CopyForAnotherThread.
parameter2: Type: TParameter2
The second parameter that is passed to the body of the loop. If this instance implements IThreadAware and IsThreadSafe returns , a copy of the parameter is made for each thread using CopyForAnotherThread.
tracker: Type: AGI.FoundationITrackCalculationProgress
The object to which progress is reported and that is able to cancel this operation before it is complete, or .
body: Type: AGI.Foundation.Infrastructure.ThreadingThreadedCalculationBodyCallbackWithProgress2TParameter1, TParameter2
The body of the loop.

Type Parameters

TParameter1: The type of the first parameter that is passed to the body of the loop.
TParameter2: The type of the second parameter that is passed to the body of the loop.
