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

Bundle.getBundleContext介绍

[英]Returns this bundle's BundleContext. The returned BundleContext can be used by the caller to act on behalf of this bundle.

If this bundle is not in the #STARTING, #ACTIVE, or #STOPPING states or this bundle is a fragment bundle, then this bundle has no valid BundleContext. This method will return null if this bundle has no valid BundleContext.
[中]返回此捆绑包的BundleContext。调用者可以使用返回的BundleContext来代表该捆绑包。
如果此捆绑包未处于#开始#活动或#停止状态，或者此捆绑包是片段捆绑包，则此捆绑包没有有效的BundleContext。如果此捆绑包没有有效的BundleContext，则此方法将返回null。
