Method: Adds the items to the trail items array for 404 pages.

Method: Adds a specific post’s parents to the items array.

Method: Adds a specific post’s hierarchy to the items array. The hierarchy is determined by post type’s rewrite arguments and whether it has an archive page.

Method: Adds a post’s terms from a specific taxonomy to the items array.

Method: Get parent posts by path. Currently, this method only supports getting parents of the ‘page’ post type. The goal of this function is to create a clear path back to home given what would normally be a “ghost” directory. If any page matches the given path, it’ll be added.

Method: Searches for term parents of hierarchical taxonomies. This function is similar to the WordPress function get_category_parents() but handles any type of taxonomy.

Method: Magic method to use in case someone tries to output the layout object as a string.

Method: Sets the labels property. Parses the inputted labels array with the defaults.

Method: Sets the `$post_taxonomy` property. This is an array of post types (key) and taxonomies (value).

Method: Runs through the various WordPress conditional tags to check the current page being viewed. Once a condition is met, a specific method is launched to add items to the `$items` array.
