function node_import_set_object in Node import 6

Store an object-id in the node_import cache.

As some string->object-id lookups can be expensive (in db queries) and most of the time the same strings are looked up (eg users), we have a cache of object-ids we already have looked up.

This function is used to store an object-id in the cache.

Parameters

$type: String. The type of object (eg 'user').

$value: String or array. The value we haved looked up.

$oid: Integer. The looked-up object-id. If NULL, the currently stored object-id is returned without setting the $type/$value to NULL. If you want to reset (eg make it NULL) a value, use

node_import_set_object($type, $value, NULL, TRUE);

$reset: Boolean. Whether to reset the cache. If $type is NULL, the whole cache is reset. If $value is not NULL only the cache for that specific $type/$value is reset.

Return value

Integer. The looked-up object-id. NULL if not found.
