Detailed Description

Opaque iterator for meta associative containers.

Constructor & Destructor Documentation

meta_iterator()

template<bool KeyOnly, typename It >

entt::meta_associative_container::meta_iterator::meta_iterator ( std::integral_constant< bool, KeyOnly >  , It  iter  )

inline

Constructs a meta iterator from a given iterator.

Template Parameters

KeyOnly	True if the associative container is also key-only, false otherwise.
It	Type of actual iterator with which to build the meta iterator.

Parameters

iter	The actual iterator with which to build the meta iterator.

Member Function Documentation

operator bool()

entt::meta_associative_container::meta_iterator::operator bool ( ) const

inlineexplicit

Returns false if an iterator is invalid, true otherwise.

Returns

False if the iterator is invalid, true otherwise.

operator!=()

bool entt::meta_associative_container::meta_iterator::operator!= ( const meta_iterator &  other ) const

inline

Checks if two meta iterators refer to the same element.

Parameters

other

The meta iterator with which to compare.

Returns

False if the two meta iterators refer to the same element, true otherwise.

operator*()

reference entt::meta_associative_container::meta_iterator::operator* ( ) const

inline

Indirection operator.

Returns

The element to which the meta pointer points.

operator++() [1/2]

meta_iterator& entt::meta_associative_container::meta_iterator::operator++ ( )

inline

Pre-increment operator.

Returns

This iterator.

operator++() [2/2]

meta_iterator entt::meta_associative_container::meta_iterator::operator++ ( int  )

inline

Post-increment operator.

Returns

This iterator.

operator==()

bool entt::meta_associative_container::meta_iterator::operator== ( const meta_iterator &  other ) const

inline

Checks if two meta iterators refer to the same element.

Parameters

other

The meta iterator with which to compare.

Returns

True if the two meta iterators refer to the same element, false otherwise.
