Restrict Custom Post Type or Taxonomy to Logged In Users

<?php
// While specified areas are under development, redirect users to home page if not logged in
add_filter( 'wp', 'f040925b_redirect', 0 );
function f040925b_redirect( $content ) {

/* Essentially, this runs three early checks:
            1) Does the $post object's post type match what you're trying to hide?
            2) Is this URL a post type archive for the post type you're trying to hide?
            3) Is this URL a taxonomy/term page for the taxonomy you're trying to hide?
 If any of these is a match and the user is not logged in, then the user is redirected to homepage. */
