Methods

buildTarget() → dynamic

使用本实例字段成员的值生成包装的目标类实例

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson() → Map<String, dynamic>

转换为基本数据类型的Map。转换结果可以直接使用jsonEncode进行序列化，可以直接保存到mongo数据库

toKValues() → Map<String, dynamic>

转换为用字符串key读取字段值的Map

toString() → String

jsonEncode(this)抛出的异常被吃掉了，所以需要写成jsonEncode(toJson())

updateByJson(Map<String, dynamic> map, {Location? parser}) → void

通过基本数据类型的Map来更新字段。来源map可以直接使用jsonEncode进行序列化，可以直接保存到mongo数据库

updateByKValues(Map<String, dynamic> map) → void

通过用字符串key读取字段值的Map来更新字段

Operators

operator ==(Object other) → bool

The equality operator.
