Detailed Description

Monostate providing hash functions.

Member Function Documentation

static constexpr Core32BitHashKey CoreHash::combine ( Core32BitHashKey  left, Core32BitHashKey  right  )

inlinestatic

Combine 2 hashes together.

Note

Implementation based on Boost (hash_combine_impl(boost::uint32_t&, boost::uint32_t) in container_hash/hash.hpp)

template<typename U , typename V , typename... W>

static constexpr Core32BitHashKey CoreHash::combine ( U  left, V  right, W...  hashes  )

inlinestatic

Helper used to combine any number of hash keys. Use it like this: ``` unsigned int hash = CoreHash::combine( CoreHash::get_hash(some_pointer), CoreHash::get_hash(some_float), some_unsigned_int ); ```

combine(Core32BitHashKey, Core32BitHashKey)

CoreString CoreHash::get_as_string ( const Core128BitHashKey &  key )

static

Serialized a 128 bits hash key to a string.

const Core128BitHashKey & CoreHash::null_key ( )

static

Get an empty 128 bits hash key.
