Detailed Description

Base (abstract) class for a jet transformer.

A transformer, when it acts on a jet, returns a modified version of that jet, one that may have a different momentum and/or different internal structure.

The typical usage of a class derived from Transformer is

   SomeTransformer transformer(...);
   PseudoJet transformed_jet = transformer(original_jet);
   // or
   vector<PseudoJet> transformed_jets = transformer(original_jets);

For many transformers, the transformed jets have transformer-specific information that can be accessed through the


See the description of the Filter class for a more detailed usage example. See the FastJet manual to find out how to implement new transformers.
