Internal.hashEnum介绍

[英]Helper method for implementing MessageLite#hashCode() for enums.

This is needed because java.lang.Enum#hashCode() is final, but we need to use the field number as the hash code to ensure compatibility between statically and dynamically generated enum objects.
[中]用于为枚举实现MessageLite#hashCode（）的助手方法。
这是必要的，因为java。lang.Enum#hashCode（）是最终的，但我们需要使用字段号作为哈希代码，以确保静态和动态生成的枚举对象之间的兼容性。
