Functions
One-to-many sequential associations
These functions allow to merge into a data collection proxy auxiliary data via an art association fulfilling the one-to-many sequential association requirement. Two categories of functions are available depending on the data source: proxy::withAssociated() reads the relevant association from an event proxy::wrapAssociated() uses an existing association objects Variants of proxy::withAssociated() called proxy::withAssociatedMeta() allow merging the metadata of an association too. The proxy::wrapAssociated() functions always merge the metadata if the wrapped association has it. Also, variants are available to customize the tag class. The implementation of this feature is documented in its own doxygen module.

This library is header-only. It provides two classes of functions:

• proxy::withAssociated(): reads and parses an association from the event
• proxy::wrapAssociated(): parses an already existing association object
