smash::ClebschGordan::ThreeSpins Struct Reference

#include <clebschgordan_lookup.h>

Auxiliary struct to be used as key in the look up table of Clebsch-Gordan coefficients.

It basically contains the input to retrieve one coefficient. Note that this is public since it is useful to be used from client code, e.g. in tests.

Member Function Documentation

tied()

auto smash::ClebschGordan::ThreeSpins::tied ( ) const

inlineprivate

A utility function to avoid duplication in comparison operator(s).

Note that in order to use auto deduced returned type, this member has to be defined before using it.

Returns

A tuple of constant references to members.

Definition at line 57 of file clebschgordan_lookup.h.

{ return std::tie(j1, j2, j3, m1, m2, m3); }

operator==()

bool smash::ClebschGordan::ThreeSpins::operator== ( const ThreeSpins &  other ) const

inline

Comparison operator between two set of spin information.

This is needed in order to use this object in a std::unordered_map container.

Parameters

other

The object to be compared to

Returns

true If all 6 spins value are identical

false otherwise
