方法
__init__([aria, clipHeight, columnPadding, ...])copy([deep, ignore])返回对象的副本。
from_dict(dct[, validate])从字典表示构建类实例。
from_json(json_string[, validate])从有效的 JSON 字符串实例化对象。
resolve_references([schema])在对象的 schema 或根 schema 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 表示作为字符串发出。
validate(instance[, schema])在 rootschema 的上下文中根据类 schema 验证实例。
validate_property(name, value[, schema])在 rootschema 的上下文中根据属性 schema 验证属性。
