Detailed Description

Iterator class for data object. The main aim of TGo4FitDataIter class is provide an sequential access to data, containing in appropriate data object. Each new class of data object should provide also it's own implementation for TGo4FitDataIrter class. To create iterator, MakeIter() method of data object should be used. Iterator has two main methods: Reset() and Next(). First method resets all internal buffers of iterator and positioning pointer on first data point. Next() method shifts to next data pointer. As argument of these methods usage of bins selection mechanism via range conditions or amplitude threshold can be specified. Typical usage of iterator:

auto iter = data->MakeIter(); if (iter->Reset()) do { // do something with values in iterator } while (iter->Next());

Access to most iterator methods like Values(), IndexesSize() and so on can be done only after first call of Reset() method.
