Either.obtainLeft介绍

[英]Utility function for EitherSerializer to support object reuse. To support object reuse both subclasses of Either contain a reference to an instance of the other type. This method provides access to and initializes the cross-reference.
[中]EitherSerializer的实用功能，支持对象重用。为了支持对象重用，其中一个的两个子类都包含对另一类型实例的引用。此方法提供对交叉引用的访问和初始化。
