Detailed Description

template<typename... FeaturesT>
struct gz::physics::FeatureList< FeaturesT >

Use a FeatureList to aggregate a list of Features.

FeatureLists can be constructed in hierarchies, e.g. a FeatureList can be passed into another FeatureList, and the set of all features in the new list will be the sum.

// FeatureA, FeatureB, AdvancedA, and AdvancedB are all feature classes.
 
using BasicList = FeatureList<FeatureA, FeatureB>;
using AdvancedList = FeatureList<BasicList, AdvancedA, AdvancedB>;

Member Typedef Documentation

Features

template<typename... FeaturesT>

using Features = typename detail::CombineLists<FeaturesT...>::Result

Features is a std::tuple containing all the feature classes that are bundled in this list. This list is fully seralialized; any hierarchy that was used to construct this FeatureList will be collapsed in this member.

FeatureTuple

template<typename... FeaturesT>

using FeatureTuple = std::tuple<FeaturesT...>

RequiredFeatures

template<typename... FeaturesT>

using RequiredFeatures = void

All the features required by this FeatureList will be included in CombineLists.

Member Function Documentation

ConflictsWith()

template<typename... FeaturesT>

template<typename SomeFeatureList , bool AssertNoConflict = false>

static constexpr bool ConflictsWith ( )

staticconstexpr

A static constexpr function which indicates whether any features in SomeFeatureList conflict with any features in SomeFeatureList.

Template Parameters

SomeFeatureList	The list to compare against for conflicts.
AssertNoConflict	Setting this to true will result in a static_assert if a conflict is found. That way, if a conflict exists, you will get a compilation error, and the compilation error will tell you which feature is conflicting.

Returns

true if any features in SomeFeatureList conflict with this list or vice versa.

HasFeature()

template<typename... FeaturesT>

template<typename F >

static constexpr bool HasFeature ( )

staticconstexpr

A static constexpr function which indicates whether a given Feature, F, is contained in this list.

Template Parameters

F	The feature class to check for in this FeatureList

Returns

true if F is in this FeatureList; false otherwise.
