Member Function Documentation

◆ clear()

template<typename Type>

bool entt::basic_meta_associative_container_traits< Type >::clear ( void * container )

inlinestaticnodiscard

Clears a container.

Parameters

container Opaque pointer to a container of the given type.

Returns: True in case of success, false otherwise.

Definition at line 216 of file container.hpp.

◆ erase()

template<typename Type>

size_type entt::basic_meta_associative_container_traits< Type >::erase	(	void *	container,
		const void *	key )

inlinestaticnodiscard

Removes an element from a container.

Parameters

container	Opaque pointer to a container of the given type.
key	An opaque key value of an element to remove.

Returns: Number of elements removed (either 0 or 1).

Definition at line 272 of file container.hpp.

◆ find()

template<typename Type>

iterator entt::basic_meta_associative_container_traits< Type >::find	(	const meta_ctx &	area,
		void *	container,
		const void *	as_const,
		const void *	key )

inlinestatic

Finds an element with a given key.

Parameters

area	The context to pass to the newly created iterator.
container	Opaque pointer to a container of the given type.
as_const	Const opaque pointer fallback.
key	Opaque key value of an element to search for.

Returns: An iterator to the element with the given key, if any.

Definition at line 284 of file container.hpp.

◆ insert()

template<typename Type>

bool entt::basic_meta_associative_container_traits< Type >::insert	(	void *	container,
		const void *	key,
		const void *	value )

inlinestaticnodiscard

Inserts an element into a container, if the key does not exist.

Parameters

container	Opaque pointer to a container of the given type.
key	An opaque key value of an element to insert.
value	Optional opaque value to insert (key-value containers).

Returns: True if the insertion took place, false otherwise.

Definition at line 258 of file container.hpp.

◆ iter()

template<typename Type>

iterator entt::basic_meta_associative_container_traits< Type >::iter	(	const meta_ctx &	area,
		void *	container,
		const void *	as_const,
		const bool	end )

inlinestatic

Returns a possibly const iterator to the beginning or the end.

Parameters

area	The context to pass to the newly created iterator.
container	Opaque pointer to a container of the given type.
as_const	Const opaque pointer fallback.
end	False to get a pointer that is past the last element.

Returns: An iterator to the first or past the last element of the container.

Definition at line 245 of file container.hpp.

◆ reserve()

template<typename Type>

bool entt::basic_meta_associative_container_traits< Type >::reserve	(	void *	container,

Parameters

container	Opaque pointer to a container of the given type.
sz	Desired capacity.

Returns: True in case of success, false otherwise.

Definition at line 227 of file container.hpp.

◆ size()

inlinestaticnodiscard

Returns the number of elements in a container.

Parameters

container Opaque pointer to a container of the given type.

Returns: Number of elements.
