WP_Rewrite::wp_rewrite_rules()

Retrieves the rewrite rules.

Description

The difference between this method and WP_Rewrite::rewrite_rules() is that this method stores the rewrite rules in the ‘rewrite_rules’ option and retrieves it. This prevents having to process all of the permalinks to get the rewrite rules in the form of caching.

Return

(array) Rewrite rules.

				add_action( 'wp_loaded', array( $this, 'flush_rules' ) );
				return $this->rules;
