/**
 * Meta API: WP_Metadata_Lazyloader class

 * @since 4.5.0
 */

/**
 * Core class used for lazy-loading object metadata.
 *
 * When loading many objects of a given type, such as posts in a WP_Query loop, it often makes
 * sense to prime various metadata caches at the beginning of the loop. This means fetching all
 * relevant metadata with a single database query, a technique that has the potential to improve
 * performance dramatically in some cases.
 *
 * In cases where the given metadata may not even be used in the loop, we can improve performance
 * even more by only priming the metadata cache for affected items the first time a piece of metadata
 * is requested - ie, by lazy-loading it. So, for example, comment meta may not be loaded into the
 * cache in the comments section of a post until the first time get_comment_meta() is called in the
 * context of the comment loop.
 *
 * WP uses the WP_Metadata_Lazyloader class to queue objects for metadata cache priming. The class
 * then detects the relevant get_*_meta() function call, and queries the metadata of all queued objects.
 *
 * Do not access this class directly. Use the wp_metadata_lazyloader() function.
 *
 * @since 4.5.0
