function hook_rebuild

hook_rebuild()

Rebuild data based upon refreshed caches.

This hook allows your module to rebuild its data based on the latest/current module data. It runs after hook_cache_flush() and after all module data has been updated.

This hook is only invoked after the system has been completely cleared; i.e., all previously cached data is known to be gone and every API in the system is known to return current information, so your module can safely rely on all available data to rebuild its own.
