Detailed Description

template<typename Aux, typename Metadata, typename ArgTuple, template< typename CollProxy > class ProxyMaker, typename AuxTag>
class proxy::details::WithAssociatedStructBase< Aux, Metadata, ArgTuple, ProxyMaker, AuxTag >

Helper to create associated data proxy.

Template Parameters

Aux	type of data associated to the main one
Metadata	type of metadata of the association
ArgTuple	type of arguments required for the creation of proxy
ProxyMaker	template type of the proxy maker class
AuxTag	tag for the associated data (default: as Aux)

This class stores user arguments for the construction of a proxy to associated data of type Aux. It can use that information plus some additional one to create the associated data itself. This additional information is provided by getCollection().

The association will be identified by type AuxTag.

This is not a customization point: to have a custom associated data produced, choose and then specialize the ProxyMaker class.
