Detailed Description

template<typename InputCollection, typename OutputCollection = InputCollection, typename P = typename edm::clonehelper::CloneTrait<InputCollection>::type>
class Merger< InputCollection, OutputCollection, P >

Merges an arbitrary number of collections into a single collection.

Template parameters:

• C : collection type
• P : policy class that specifies how objects in the collection are are cloned
