Overview

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.

Actually update the resource list, assuming anything has called rebuild_resource_list! since the last time it was run. This is very expensive!

#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.

Parameters:

  • name (Symbol) —

    Name of the manipulator for debugging

  • manipulator (#manipulate_resource_list) —

    Resource list manipulator

  • priority (Numeric) —

    Sets the order of this resource list manipulator relative to the rest. By default this is 50, and manipulators run in the order they are registered, but if a priority is provided then this will run ahead of or behind other manipulators.
