Detailed Description

template<class T, class S, class H = ProductFromFwdPtrFactory<T>>
class edm::FwdPtrCollectionFilter< T, S, H >

Selects a list of FwdPtr's to a product T (templated) that satisfy a method S(T) (templated). Can also handle input as View<T>. Can also have a factory class to create new instances of clones if desired.
