function views_object_cache_get

Get an object from the non-volatile Views cache.

This function caches in memory as well, so that multiple calls to this will not result in multiple database reads.

Parameters

$obj: A 32 character or less string to define what kind of object is being stored; primarily this is used to prevent collisions.

$name: The name of the view (or other object) being stored.

$skip_cache: Skip the memory cache, meaning this must be read from the db again.

Return value

The data that was cached.
