本文整理了Java中org.osgi.framework.hooks.weaving.WovenClass类的一些代码示例,展示了WovenClass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。WovenClass类的具体详情如下:
包路径:org.osgi.framework.hooks.weaving.WovenClass
类名称:WovenClass

WovenClass介绍

[英]A class being woven. This object represents a class being woven and is passed to each WeavingHook for possible modification. It allows access to the most recently transformed class file bytes and to any additional packages that should be added to the bundle as dynamic imports.

Upon entering one of the terminal states, this object becomes effectively immutable.
[中]正在编织的课程。此对象表示正在编织的类,并传递给每个编织钩进行可能的修改。它允许访问最近转换的类文件字节,以及应作为动态导入添加到包中的任何附加包。
当进入一个终端状态时,这个对象实际上是不可变的。
