本文整理了Java中org.apache.tiles.request.Request.getContext方法的一些代码示例，展示了Request.getContext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。Request.getContext方法的具体详情如下：
包路径：org.apache.tiles.request.Request
类名称：Request
方法名：getContext

Request.getContext介绍

[英]Returns a context map, given the scope name. This method always return a map for all the scope names returned by getAvailableScopes(). That map may be writable, or immutable, depending on the implementation.
[中]返回给定作用域名称的上下文映射。此方法始终为getAvailableScopes（）返回的所有作用域名称返回一个映射。该映射可能是可写的，也可能是不可变的，具体取决于实现。
