# AsdfOrderedDictNode

class asdf.lazy_nodes.AsdfOrderedDictNode(data=None, af_ref=None)

  Bases: `AsdfDictNode`, `OrderedDict`

  An class that acts like a `collections.OrderedDict`. The values for this `OrderedDict` will start out as tagged nodes which will only be converted to custom objects the first time the corresponding key is used (the custom object will then be cached for later reuse).
