What is the best way to get the hierarchy of parent category objects from the category.php template, when there is no post as such.
The function get_category_parents() returns a string not the objects.
The function get_categories() seems to be intended for pages where there is a post because the type argument can take either post or link.
Is there any other function I am missing? I would need something that behaves exactly like get_category_parents() but I need the category objects not just a string of all of the names.

Reset to default 1I am not aware of a built in function that does what you are asking but it is not that hard to cook up. In fact, you are pretty close. get_categories is correct but it needs the child_of argument, which means finding the topmost parent via get_ancestors. child_of will only return children, not the specified parent, so that parent has to be inserted into the results manually.
var_dump(get_category_parents(5)); // reference
$anc = get_ancestors(5,'category');
$parent = array_pop($anc);
$hier[] = get_category($parent);
$args = array(
'child_of' => $parent,
);
array_push($hier,get_categories($args));
var_dump($hier);
