Detailed Description

template<typename Collection>
class CollectionCombiner< Collection >

Description: this templated EDProducer can merge (no duplicate removal) any number of collection of the same type. the usage is to declare a concrete combiner in SealModule: typedef CollectionCombiner<std::vector< Trajectory> > TrajectoryCombiner; DEFINE_FWK_MODULE(TrajectoryCombiner); edm::View cannot be used, because the template argument is used for the input and the output type.
