ObjectContainer

template<template< typename... > class Container, typename ManagedType , class BaseType , class = std::enable_if_t<std::is_base_of_v<ObjectHandle, ManagedType>>>

using ScriptInterface::ObjectContainer = typedef std::conditional_t< std::is_same_v<BaseType, ObjectHandle>, AutoParameters<Container<ManagedType, BaseType>, BaseType>, BaseType>

Base class for containers whose BaseType might be a full specialization of AutoParameters.

Definition at line 36 of file ObjectContainer.hpp.

ObjectId

using ScriptInterface::ObjectId = typedef std::size_t

Definition at line 32 of file packed_variant.hpp.

ObjectRef

using ScriptInterface::ObjectRef = typedef std::shared_ptr<ObjectHandle>

Definition at line 59 of file Variant.hpp.

PackedMap

using ScriptInterface::PackedMap = typedef std::vector<std::pair<std::string, PackedVariant> >

Definition at line 62 of file packed_variant.hpp.

PackedVariant

using ScriptInterface::PackedVariant = typedef boost::make_recursive_variant< None, bool, int, std::size_t, double, std::string, ObjectId, Utils::Vector3b, Utils::Vector3i, Utils::Vector2d, Utils::Vector3d, Utils::Vector4d, std::vector<int>, std::vector<double>, std::vector<boost::recursive_variant_>, std::unordered_map<int, boost::recursive_variant_>, std::unordered_map<std::string, boost::recursive_variant_> >::type

Packed version of Variant.

When packing variants by PackVisitor, objects of type ObjectRef are packed as ObjectId. Other than that, all other types allowed in Variant must appear here.

Definition at line 54 of file packed_variant.hpp.

Variant

using ScriptInterface::Variant = typedef boost::make_recursive_variant< None, bool, int, std::size_t, double, std::string, ObjectRef, Utils::Vector3b, Utils::Vector3i, Utils::Vector2d, Utils::Vector3d, Utils::Vector4d, std::vector<int>, std::vector<double>, std::vector<boost::recursive_variant_>, std::unordered_map<int, boost::recursive_variant_>, std::unordered_map<std::string, boost::recursive_variant_> >::type

Possible types for parameters.

The visitors and packing functions need to be adapted accordingly when extending this variant with new types. For the exact details, see commit b48ab62. The number of types is limited by macro BOOST_MPL_LIMIT_LIST_SIZE (defaults to 20).

VariantMap

using ScriptInterface::VariantMap = typedef std::unordered_map<std::string, Variant>

Definition at line 82 of file Variant.hpp.

Function Documentation

get_value() [1/2]

template<typename T >

T ScriptInterface::get_value

(

Variant const &

v

)

Extract value of specific type T from a Variant.

This is a wrapper around boost::get that allows us to customize the behavior for different types. This is needed e.g. to deal with containers whose elements have mixed types that are implicitly convertible to a requested type.
