Detailed Description

template<template< int i > typename ValueType>
class operations_research::math_opt::AttrMap< ValueType >

A map of attribute to ValueType<i>, where i is the index of the attribute type. See AttrMapTest for example usage.

Note

this is formally a map (it maps attributes to values), but internally uses dense storage.

Member Function Documentation

ForEachAttrValue()

template<template< int i > typename ValueType>

template<typename Fn>

void operations_research::math_opt::AttrMap< ValueType >::ForEachAttrValue ( Fn && fn )

inline

Applies fn on each value for each attribute type. fn must have a overload set of operator() that accepts a ValueType<i> for i in 0..AllAttrs::kSize. This cannot be an iterator because value types are not homogeneous.

operator[]() [1/2]

template<template< int i > typename ValueType>

template<typename AttrT>

ValueType< AllAttrs::GetIndex< AttrT >()> & operations_research::math_opt::AttrMap< ValueType >::operator[] ( AttrT a )

inline

Todo

(b/365997645): post C++ 23, prefer std::to_underlying(a).

operator[]() [2/2]

template<template< int i > typename ValueType>

template<typename AttrT>

const ValueType< AllAttrs::GetIndex< AttrT >()> & operations_research::math_opt::AttrMap< ValueType >::operator[] ( AttrT a ) const

inline

The const_cast is fine because non-const operator[] does not mutate anything and we're casting the return type back to const.
