66 class SerializingObject(object):
68 Common ancestor for TaskResource & TaskFilter, since they both
69 need to serialize arguments.
71 Serializing method should hold the following contract:
72 - any empty value (meaning removal of the attribute)
73 is deserialized into a empty string
74 - None denotes a empty value for any attribute
76 Deserializing method should hold the following contract:
77 - None denotes a empty value for any attribute (however,
78 this is here as a safeguard, TaskWarrior currently does
79 not export empty-valued attributes) if the attribute
80 is not iterable (e.g. list or set), in which case
81 a empty iterable should be used.
83 Normalizing methods should hold the following contract:
84 - They are used to validate and normalize the user input.
85 Any attribute value that comes from the user (during Task
86 initialization, assignign values to Task attributes, or
87 filtering by user-provided values of attributes) is first
88 validated and normalized using the normalize_{key} method.
89 - If validation or normalization fails, normalizer is expected
