Mapping

Mapping is a special Apex class that gives Adapters and Filters info about the mappings a user has defined for the Link.

Mappings can be found as a property inside a LinkContext.

The Mapping class is pretty straightforward, the only thing that is a little special is the configuration property. It is contextually-sensitive, so for example if you are inspecting the Mappings from inside your custom Filter, if there’s a value inside configuration it is because a user has specifically set a configuration for YOUR Filter on THIS Link, so go ahead and use it.

For more information about mapping configurations, check out ConfigurablePerMappingFilter.
