openforcefield.utils.serialization.Serializable

class openforcefield.utils.serialization.Serializable

Mix-in to add serialization and deserialization support via JSON, YAML, BSON, TOML, MessagePack, and XML.

For more information on these formats, see: JSON, BSON, YAML, TOML, MessagePack, and XML.

To use this mix-in, the class inheriting from this class must have implemented to_dict() and from_dict() methods that utilize dictionaries containing only serialiable Python objects.

Warning

The serialization/deserialiation schemes used here place some strict constraints on what kinds of dict objects can be serialized. No effort is made to add further protection to ensure serialization is possible. Use with caution.

Examples

Example class using Serializable mix-in:

>>> from openforcefield.utils.serialization import Serializable
>>> class Thing(Serializable):
...     def __init__(self, description):
...         self.description = description
...
...     def to_dict(self):
...         return { 'description' : self.description }
...
...     @classmethod
...     def from_dict(cls, d):
...         return cls(d['description'])
...
>>> # Create an example object
>>> thing = Thing('blorb')

Get JSON representation:

>>> json_thing = thing.to_json()

Reconstruct an object from its JSON representation:

>>> thing_from_json = Thing.from_json(json_thing)

Get BSON representation:

>>> bson_thing = thing.to_bson()

Reconstruct an object from its BSON representation:

>>> thing_from_bson = Thing.from_bson(bson_thing)

Get YAML representation:

>>> yaml_thing = thing.to_yaml()

Reconstruct an object from its YAML representation:

>>> thing_from_yaml = Thing.from_yaml(yaml_thing)

Get MessagePack representation:

>>> messagepack_thing = thing.to_messagepack()

Reconstruct an object from its MessagePack representation:

>>> thing_from_messagepack = Thing.from_messagepack(messagepack_thing)

Get XML representation:

>>> xml_thing = thing.to_xml()
