variant

Fully qualified name: carb::variant

namespace variant

Namespace for carb.variant.plugin and related utilities.

Classes

Registrar

Lifetime management wrapper for IVariant::registerType() .

Variant

A wrapper class for managing the lifetime of VariantData and converting the contained value to C++ types.

VariantArray

An array-of-variants type that can itself be contained in a Variant .

VariantMap

An associative array (i.e.

Functions

bool operator!=(const Variant &lhs, const Variant &rhs)

Tests for inequality between two variants.

bool operator==(const Variant &lhs, const Variant &rhs)

Tests for equality between two variants.

VariantData translate(Type &&type) noexcept

A helper function to translate a typed value into a VariantData via a Translator .

Structs

IVariant

Interface for carb.variant.plugin

KeyValuePair

A representation of a key value pair, similar to std::pair<const Variant, Variant> .

Translator

Default implementation of a Translator type.

VTable

A v-table definition for a variant type. Each registered type has a unique v-table pointer that is retrievable via IVariant::getVTable() . Each entry in the v-table is a function with a default behavior if nullptr .

VariantData

A standard-layout.

traits

A structure containing functions for performing the prescribed actions on a VariantData . The functions handle the default behavior if the v-table or v-table function are nullptr .

Typedefs

VariantArrayPtr

Helper definition.

VariantMapPtr

Helper definition.
