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 vignettecaching
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
