Returns results from the in-memory cache, filtered by ids
if given.
Cache must be created first using banc_meta_create_cache()
.
Details
banc_meta()
never queries databases directly.
If ids
are given, filters the meta table by root_id.
Examples
if (FALSE) { # \dontrun{
banc_meta_create_cache() # build the cache
all_meta <- banc_meta() # retrieve all
} # }
