Detailed Description

template<typename T>
class TTClusterAssociator< T >

Plugin to create the MC truth for TTClusters.

After moving from SimDataFormats to DataFormats, the template structure of the class was maintained in order to accomodate any types other than PixelDigis in case there is such a need in the future.

Constructor & Destructor Documentation

template<typename T >

TTClusterAssociator< T >::TTClusterAssociator ( const edm::ParameterSet & iConfig )

explicit

Constructors.

Close class.

NOTE since pattern hit correlation must be performed within a stacked module, one must store Clusters in a proper way, providing easy access to them in a detector/member-wise way

Implementation of methods

Here, in the header file, the methods which do not depend on the specific type <T> that can fit the template. Other methods, with type-specific features, are implemented in the source file.Constructors
