◆ doFinish()

bool ReflectivitySampler::doFinish ( bool success )

overrideprivatevirtual

Called after all doWork have finished.

Parameters

success indicates whether all doWork returned true.

Reimplemented from ParallelTask.

◆ doPrepare()

bool ReflectivitySampler::doPrepare ( int nrthreads )

overrideprivatevirtual

Called once, before any doWork is called.

Reimplemented from ParallelTask.

◆ doWork()

bool ReflectivitySampler::doWork	(	od_int64	start,
		od_int64	stop,
		int	threadidx )

overrideprivatevirtual

The functions that does the job. The function will be called with all intervals from 0 to ParallelTask::nrIterations()-1. The function must be designed to be able to run in parallel.

Parameters

start	first index
stop	last index
threadidx	gives an identifier (between 0 and nr of threads -1) that is unique to each call to doWork.

Implements ParallelTask.

◆ nrIterations()

Returns: the number of times the process should be run.
