:relfileprefix: ../../
:mrdocs:

This class wraps the (template parameter) `HASH_ALGORITHM`, which requires a seed, in an interface that satisfies the `hash` requirements of the C++11 standard. The (template parameter) type `SEED_GENERATOR` will be used to generate the seed required by `HASH_ALGORITHM`.
