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

WovenClass.getDynamicImports介绍

[英]Returns the list of dynamic import package descriptions to add to the #getBundleWiring() for this woven class. Changes made to the returned list will be visible to later WeavingHook called with this object. The returned list must not be modified outside invocations of the WeavingHook#weave(WovenClass) method by the framework.

After leaving the #TRANSFORMING state, this woven class can no longer be transformed and the returned list will be unmodifiable.

If the Java runtime environment supports permissions, any modification to the returned list requires AdminPermission[bundle,WEAVE]. Additionally, any add or set modification requires PackagePermission[package,IMPORT].
[中]返回要添加到此编织类的#getBundleWiring()中的动态导入包描述列表。对返回列表所做的更改将在以后使用此对象调用WeavingHook时可见。在框架调用WeavingHook#weave(WovenClass)方法之外,不能修改返回的列表。
离开#转换状态后,这个编织类将无法再被转换,返回的列表将不可修改。
如果Java运行时环境支持权限,那么对返回列表的任何修改都需要AdminPermission[bundle,WEAVE]。此外,任何添加或设置修改都需要PackagePermission[打包,导入]。
