Detailed Description

template<typename T>
class TTClusterBuilder< T >

Plugin to load the Clustering algorithm and produce the collection of Clusters that goes in the event content.

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.

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

Prepare output

Temp vectors containing the vectors of the hits used to build each cluster




Find the hits in each stack member

If there are hits, cluster them It is the TTClusterAlgorithm::Cluster method which calls the constructor to the Cluster class!


Create TTCluster objects and store them Use the FastFiller with edmNew::DetSetVector

End of loop over detector elements

Put output in the event
