Check if given items are present in cache

Description

Check if given items are present in cache

Usage

tw_check_cached_items(
  id,
  language = tidywikidatar::tw_get_language(),
  cache_connection = NULL,
  disconnect_db = TRUE
)

Arguments

id	A character vector. Each element must start with Q, and correspond to a Wikidata identifier.
language	Defaults to language set with tw_set_language(); if not set, "en". Use "all_available" to keep all languages. For available language values, see https://www.wikidata.org/wiki/Help:Wikimedia_language_codes/lists/all
cache_connection	Defaults to NULL. If NULL, and caching is enabled, tidywikidatar will use a local sqlite database. A custom connection to other databases can be given (see vignette caching for details).
disconnect_db	Defaults to TRUE. If FALSE, leaves the connection to cache open.

Value

A character vector with IDs of items present in cache. If no item found in cache, returns NULL.

Examples

if (interactive()) {
  tw_set_cache_folder(path = tempdir())
  tw_enable_cache()
  tw_create_cache_folder(ask = FALSE)

  # add three items to local cache
  invisible(tw_get(id = "Q180099", language = "en"))
  invisible(tw_get(id = "Q228822", language = "en"))
  invisible(tw_get(id = "Q184992", language = "en"))

  # check if these other items are in cache
  items_in_cache <- tw_check_cached_items(
    id = c(
      "Q180099",
      "Q228822",
      "Q76857"
    ),
    language = "en"
  )
  # it should return only the two items from the current list of id
  # but not other item already in cache
  items_in_cache
}
