namespace variations {

// Provides a mapping from hashes of generated resource names to their IDs. The
// mapping is provided by the embedder as two arrays |resource_hashes|, a sorted
// array of resource name hashes, and |resource_indices| an array of resource
// indices in the same order.
//
// The mapping is created by generate_ui_string_overrider.py based on generated
// resources header files. The script ensure that if one header file contains
// |#define IDS_FOO 12345| then for some index |i|, |resource_hashes[i]| will
// be equal to |HASH("IDS_FOO")| and |resource_indices[i]| will be equal to
// |12345|.
//
// Both array must have the same length |num_resources|. They are not owned by
// the UIStringOverrider and the embedder is responsible for their lifetime
// (usually by passing pointer to static data).
//
// This class is copy-constructible by design as it does not owns the array
// and only have reference to globally allocated constants.
