Tag | tag for the association proxy to be created |
withAssociated()
This class is (indirectly) called when using proxy::withAssociated()
in getCollection()
. Its task is to supervise the creation of the proxy to the data association between the main data type and an auxiliary one. The interface required by withAssociated()
includes:make()
method creating and returning the associated data proxy with arguments an event, the main data product handle, a template argument representing the main collection information, and all the arguments required for the creation of the associated proxy (coming from withAssociated()
); equivalent to the signature: This class can be specialized (see withAssociated()
for an example). The default implementation just wraps a one-to-many art::Assns<Main, Aux>
data product fulfilling "one-to-many sequential
association" requirement (see the "Definitions" section in ProxyBase.h
documentation).
The last template argument is designed for specialization of associations in the context of a specific proxy type.

Create a association proxy collection using main collection tag.
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 |
event | the event to read associations from |
mainHandle | handle to the main collection data product |
mainArgs | an object describing the main data product |
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.

Create a association proxy collection using main collection tag.
Event | type of the event to read associations from |
Handle | type of data product handle |
MainArgs | any type convertible to art::InputTag |
Args | optional single type (art::InputTag required) |
event | the event to read associations from |

margs | an object describing the main data product |
args | input tag for associated data, if different from main |
The returned object exposes a random access container interface, with data indexed by the index of the corresponding object in the main collection.
This implementation requires margs
object to be convertible by explicit type cast into a art::InputTag
; that input tag will be used to fetch the association.
