template<typename SystemContext SystemContext, typename Element Element>
gtopt::ElementTraits struct

Defines default traits for element access and manipulation.

Template parameters
SystemContext The context providing access to the system model.
Element The type of element these traits are for.

This traits struct provides a generic implementation for interacting with elements within a SystemContext. It forwards calls to the underlying SystemLP object.

Public static functions

template<template<typename> class Id>
static auto get_element(SystemContext& sc, const Id<Element>& id) -> constexpr auto&&
Gets a reference to an element by its ID.
template<template<typename> class Id>
static auto get_element_index(SystemContext& sc, const Id<Element>& id) -> constexpr auto
Gets the index of an element by its ID.
static auto get_elements(SystemContext& sc) -> constexpr auto&& noexcept
Gets a container of all elements of a specific type.
template<typename ElementType2 ElementType2>
static auto push_back(SystemContext& sc, ElementType2&& e) -> constexpr auto
Adds a new element to the system.

Function documentation

template<typename SystemContext SystemContext, typename Element Element> template<template<typename> class Id>
static constexpr auto&& gtopt::ElementTraits<SystemContext, Element>::get_element(SystemContext& sc, const Id<Element>& id)

Gets a reference to an element by its ID.

Parameters
sc The system context.
id The ID of the element.
Returns A reference to the element.

Routes through sc.get_element(id) — a fully-inline template in system_context.hpp using void* dispatch — so that call sites do NOT need to include system_lp.hpp to instantiate this template.

template<typename SystemContext SystemContext, typename Element Element> template<template<typename> class Id>
static constexpr auto gtopt::ElementTraits<SystemContext, Element>::get_element_index(SystemContext& sc, const Id<Element>& id)

Gets the index of an element by its ID.

Parameters
sc The system context.
id The ID of the element.
Returns The ElementIndex for the given ID.

template<typename SystemContext SystemContext, typename Element Element>
static constexpr auto&& gtopt::ElementTraits<SystemContext, Element>::get_elements(SystemContext& sc) noexcept

Gets a container of all elements of a specific type.

Parameters
sc The system context.
Returns A reference to the container of elements.

template<typename SystemContext SystemContext, typename Element Element> template<typename ElementType2 ElementType2>
static constexpr auto gtopt::ElementTraits<SystemContext, Element>::push_back(SystemContext& sc, ElementType2&& e)

Adds a new element to the system.

Parameters
sc The system context.
e The element to add.
Returns The ElementIndex of the newly added element.
