Sample: registerPostType

In my abstract I have methods like the following.

 public function registerPostType( $args=NULL ) {

        foreach ( $this->post_type as $post_type ) {

            if ( !empty( $post_type['taxonomies'] ) )                                
                $taxonomies = $post_type['taxonomies'];       
            .
            .
            .
            .
            $labels = array(
                'name' => _x( $post_type['name'], 'post type general name'),
                'singular_name' => _x( $post_type['singular_name'], 'post type singular name'),
                'add_new' => _x('Add New ' . $post_type['singular_name'] . '', 'something'),
                'add_new_item' => __('Add New ' . $post_type['singular_name'] . ''),
                'edit_item' => __('Edit '. $post_type['singular_name'] .''),
                'new_item' => __('New '. $post_type['singular_name'] .''),
                'view_item' => __('View '. $post_type['singular_name'] . ''),
                'search_items' => __('Search ' . $post_type['singular_name'] . ''),
                'not_found' => __('No ' . $post_type['singular_name'] . ' found'),
                'not_found_in_trash' => __('No ' . $post_type['singular_name'] . ' found in Trash'),
                'parent_item_colon' => ''
                );

            .
            .
            .

        register_post_type( $post_type['type'], $args);

     } // End 'foreach'         

     return $this->post_type;
}
