Detailed Description

Opaque container for meta constructors.

Member Typedef Documentation

size_type

using entt::meta_ctor::size_type = typename internal::meta_ctor_node::size_type

Unsigned integer type.

Constructor & Destructor Documentation

meta_ctor()

entt::meta_ctor::meta_ctor ( const internal::meta_ctor_node *  curr = nullptr )

inline

Constructs an instance from a given node.

Parameters

curr	The underlying node with which to construct the instance.

Member Function Documentation

arg()

meta_type entt::meta_ctor::arg ( size_type  index ) const

inline

Returns the meta type of the i-th argument of a meta constructor.

Parameters

index

The index of the argument of which to return the meta type.

Returns

The meta type of the i-th argument of a meta constructor, if any.

invoke()

template<typename... Args>

meta_any entt::meta_ctor::invoke ( Args &&...  args ) const

inline

Creates an instance of the underlying type, if possible.

To create a valid instance, the types of the parameters must coincide exactly with those required by the underlying meta constructor. Otherwise, an empty and then invalid container is returned.

Template Parameters

Args	Types of arguments to use to construct the instance.

Parameters

args	Parameters to use to construct the instance.

Returns

A meta any containing the new instance, if any.

operator bool()

entt::meta_ctor::operator bool ( ) const

inlineexplicit

Returns true if a meta object is valid, false otherwise.

Returns

True if the meta object is valid, false otherwise.

operator==()

bool entt::meta_ctor::operator== ( const meta_ctor &  other ) const

inline

Checks if two meta objects refer to the same node.

Parameters

other

The meta object with which to compare.

Returns

True if the two meta objects refer to the same node, false otherwise.

parent()

meta_type entt::meta_ctor::parent ( ) const

inline

Returns the meta type to which a meta object belongs.

Returns

The meta type to which the meta object belongs.

prop() [1/2]

template<typename Op >

std::enable_if_t<std::is_invocable_v<Op, meta_prop>, void> entt::meta_ctor::prop ( Op  op ) const

inline

Iterates all the properties assigned to a meta constructor.

Template Parameters

Op	Type of the function object to invoke.

Parameters

op	A valid function object.

prop() [2/2]

meta_prop entt::meta_ctor::prop ( meta_any  key ) const

inline

Returns the property associated with a given key.

Parameters

key	The key to use to search for a property.

Returns

The property associated with the given key, if any.

size()

size_type entt::meta_ctor::size ( ) const

inline

Returns the number of arguments accepted by a meta constructor.

Returns

The number of arguments accepted by the meta constructor.
