方法
__init__([field, timeUnit])copy([deep, ignore])返回对象的副本。
from_dict(dct[, validate])从字典表示构建类。
from_json(json_string[, validate])从有效的 JSON 字符串实例化对象。
resolve_references([schema])在该对象模式或根模式的上下文中解析引用。
to_dict([validate, ignore, context])返回对象的字典表示。
to_json([validate, indent, sort_keys, ...])将此对象的 JSON 表示输出为字符串。
validate(instance[, schema])在根模式的上下文中验证实例是否符合类模式。
validate_property(name, value[, schema])在根模式的上下文中验证属性是否符合属性模式。
