Custom Property Types

class lfview.resources.spatial.base.InstanceSnapshot(doc, instance_class, **kwargs)

Instance property that can serialize to JSON string

This property type inherits from properties.Instance. However, it overrides the serializer and deserializer with custom methods that allow serialization to JSON string. To access this behavior, pass snapshot=True key word argument into serialize.

class lfview.resources.spatial.base.ShortString(doc, **kwargs)

String property with maximum length

Available keywords (in addition to those inherited from properties.String):

• max_length - If specified, the length of the string is validated to be less than or equal to this value.
