Functions
One-to-one (optional) associations
These functions allow to merge into a data collection proxy some auxiliary data via an art association fulfilling the one-to-(zero-or-one) sequential association requirement. One category of functions is currently available: proxy::withZeroOrOne() reads the relevant association from an event Variants of proxy::withZeroOrOne() called proxy::withZeroOrOneMeta() will allow merging the metadata of an association too. This feature is not supported yet, though. Also, variants are available to customize the tag class. The implementation of this feature is documented in its own doxygen module.
