Short-circuits the return value of a meta field.
The dynamic portion of the hook name, $meta_type, refers to the meta object type
(post, comment, term, user, or any other type with an associated meta table).
Returning a non-null value will effectively short-circuit the function.
Possible filter names include:
get_post_metadataget_comment_metadataget_term_metadataget_user_metadata
$check = apply_filters( "get_{$meta_type}_metadata", null, $object_id, $meta_key, $single, $meta_type );
