Detailed Description

Base class for implementing data iterators.

Each data iterator handles a single stream of data. All derived classes must implement the GetNext() method and override the Seek() method appripriately.

The documentation for this class was generated from the following files:

src/datahandler.h
src/datahandler.cc
