Less

template<typename TValueType, typename TSfinae = void>
struct libsemigroups::Less

Adapter for comparisons.

Defined in adapters.hpp.

This type should be a stateless trivially default constructible with a call operator of signature bool operator()(TValueType const&, TValueType const&) (possibly noexcept, inline and/or constexpr also) which defines a linear order on the objects of type TValueType

Used by:

• FroidurePinTraits

Template Parameters

• TValueType – the type of objects to compare.

• TSfinae – this template parameter can be used for SFINAE.

Public Functions

inline bool operator()(TValueType const &x, TValueType const &y) const

This call operator compares x and y using std::less with template parameter TValueType.
