	same as reference
using	IOTypes = std::tuple< AIOTypes... >
	Types that should be served to apply on invokation.
using	IOVectors = std::tuple< std::vector< AIOTypes >... >
	Vector types that should be served to apply on invokation.

Detailed Description

template<class TWrappedFindlet>
class Belle2::TrackFindingCDC::FindletStoreArrayInput< TWrappedFindlet >

Findlet which can wrap another Findlet and forward the contents of a StoreArray to the wrapped findlet.

This simplifies development of findlets who can either be used stand-alone (with input from a StoreArray) or within a more complex findlet chain with input from, for example, an std::vector. For an example, see the TrackTimeExtractionModule

Internally, this class uses the StoreArrayLoader to transfer the pointers from a StoreArray to an std::vector for each event.
