The Store class

The Store manages a collection of Resource objects, which represent individual items in the sitemap. Resources are indexed by "source path", which is the path relative to the source directory, minus any template extensions. All "path" parameters used in this class are source paths.

#Symbol

This method returns an undefined value.

Register an object which can transform the sitemap resource list. Best to register these in a before_configuration or after_configuration hook.
