Detailed Description

template<typename Main, typename Aux, typename Metadata, typename AuxTag = Aux>
struct proxy::AssociatedDataProxyMakerBase< Main, Aux, Metadata, AuxTag >

Creates an associated data wrapper for the specified types.

Template Parameters

Main	type of main datum (element) to associate from ("left")
Aux	type of datum (element) to associate to ("right")
AuxTag	tag labelling this association

Usually, AuxTag is also the type of datum (element) to associate to ("right").

This class works as a base class for AssociatedDataProxyMaker so that the specializations of the latter can still inherit from this one if they its facilities.

inlinestatic

Create a association proxy collection using main collection tag.

Template Parameters

Event	type of the event to read associations from
Handle	type of handle to the main data product
MainArgs	any type convertible to `art::InputTag`

Parameters

event	the event to read associations from
mainHandle	handle to the main collection data product
mainArgs	an object describing the main data product

Returns: an auxiliary data proxy object

The returned object exposes a random access container interface, with data indexed by the index of the corresponding object in the main collection.

The mainArgs object is of an arbitrary type that must be convertible by explicit type cast into a art::InputTag; that input tag will be used to fetch the association.

Parameters

event	the event to read associations from
