Updates the persistent caches for the next usage. This function not only stores the data of the textgroup objects but also of the string objects. That way we ensure that only cacheable string object go into the persistent cache.

Class

i18n_string_textgroup_cached

Textgroup handler for i18n_string API which integrated persistent caching.

Code

public function __destruct() {

  // Reduce size to cache by removing NULL values.
  $this->strings = array_filter($this->strings);
  $strings_to_cache = array();

  // Store the persistent caches. We just store the metadata the translations
  // are stored by the string object itself. However storing the metadata
  // reduces the number of DB queries executed during runtime.
  $cache_data = array();

    $cache_data[$context] = $context;
    $strings_to_cache[$context] = $i18n_string_object;

  // Store only the public visible data into the persistent cache.

    // to be stored again.
