classLineReader
¶ Read data from a stream one line at a time.
This class is an adapter that takes a std::istream as input and provides an InputIterator that loops over the lines of the stream. In its current version it delegates to the getline() function to determine when a line has ended.
The behavior is meant to be the same as the Python idiom
for line in file
.We do not expect you to instantiate this class directly. Instead, it shows up as part of PointReader where you put a stream in one end and get points out the other end.
