PointFromTokensReader module¶

Module contents¶

template<typename PointT, typename SourceIterT> class PointFromTokensReader : public tracktable::GenericReader<PointT>¶

Read points from lists of tokens.

PointFromTokensReader expects as its input an iterator that will yield iterator ranges. That is, each value of the iterator is a (begin, end) pair of iterators that will produce a set of tokens for one point.

Think of it with this common use case. Somewhere upstream you are reading lines from a text file. Your reader takes lines from the file and separates each line into a list of tokens using some delimiter. PointFromTokensReader takes each of those lists of tokens, one list at a time, and turns it into a point of some user-requested type.
