[req.hash_compare]

HashCompare is an object which is used to calculate hash code for an object and compare two objects for equality.

The type H satisfies HashCompare if it meets the following requirements:


HashCompare Requirements: Pseudo-Signature, Semantics

H::H(const H&)#

Copy constructor.

H::~H()#

Destructor.

std::size_t H::hash(const KeyType &k) const#

Calculates the hash for a provided key.

ReturnType H::equal(const KeyType &k1, const KeyType &k2) const#

Requirements:

  • The type ReturnType should be implicitly convertible to bool.

Compares k1 and k2 for equality.

If this function returns true, H::hash(k1) should be equal to H::hash(k2).
