Detailed Description

Example class that can be used both within FWLite and within the full framework.

This is an example for keeping classes that can be used both within FWLite and within the full framework. The class is derived from the BasicAnalyzer base class, which is an interface for the two wrapper classes EDAnalyzerWrapper and FWLiteAnalyzerWrapper. The latter provides basic configuration file reading and event looping equivalent to the FWLiteHistograms executable of this package. You can see the FWLiteAnalyzerWrapper class at work in the FWLiteWithBasicAnalyzer executable of this package.
