It is also assumed that any lists in the JSON object contain objects of the same type, so the ":types:" dictionary does not contain lists a list at that level but the type information for every element of the list.

A few top-level keys have predefined types, reflecting their use as in configuration objects.  These reserved keys are:

In order to simplify the creation of typed JSON objects, the typed_json module defines the cdict class.  The constructor for this class takes an optional argument which is either an instance of another cdict or a dictionary representing a typed JSON object that is used to initialize the new cdict.  The main methods for this class are:

• set(name, value, type="INT32", override=False, append=False)
• setInfo(detType=None, detName=None, detId=None, doc=None)
  Set the top-level reserved keys to the specified values.
• setAlg(alg, version=[0,0,0], doc="")
  Set the top-level "alg" key to a dictionary containing the arguments.
• set(name, value, type="INT32", override=False, append=False)
  The "name" parameter is a "flattened" name with dot-separated fields.  XXX
• typed_json()
  Return a dictionary representing a typed JSON object (with the ":types:" key, etc.)
• get(name, withtype=False)
• getenumdict(name, reverse=False)
• define_enum(name, value)
