本文整理了Java中org.ff4j.core.Feature类的一些代码示例，展示了Feature类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Feature类的具体详情如下：
包路径：org.ff4j.core.Feature
类名称：Feature

Feature介绍

[英]Represents a feature flag identified by an unique identifier.

Features Flags or Features Toggle have been introduced by Martin Fowler for continuous delivery perspective. It consists of enable/disable some functionalities at runtime.

SecurityManagement : Even a feature is enabled, you can limit its usage to a group of users (for instance BETA Tester) before wide over all your users.
[中]表示由唯一标识符标识的特征标志。
Martin Fowler为连续交付透视图引入了功能标志或功能切换。它包括在运行时启用/禁用某些功能。
SecurityManagement：即使启用了某个功能，您也可以在覆盖所有用户之前将其使用限制在一组用户（例如BETA-Tester）。
