function _ctools_export_get_defaults_from_cache in Chaos Tool Suite (ctools) 7

Attempt to load default objects from cache.

We can be instructed to cache default objects by the schema. If so we cache them as an index which is a list of all default objects, and then each default object is cached individually.

Return value

Either an array of cached objects, or NULL indicating a cache rebuild is necessary.

Code

function _ctools_export_get_defaults_from_cache($table, $export) {
  $data = cache_get('ctools_export_index:' . $table, $export['default cache bin']);
  if (!$data || !is_array($data->data)) {
    return;

  // This is the perfectly valid case where there are no default objects,
  // and we have cached this state.

  // If any of our indexed keys missed, then we have a fail and we need to
  // rebuild.

    return;
  }

  // Now, translate the returned cache objects to actual objects.
  $cache = array();
