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

Body.getUnits介绍

[英]Returns the Chain of Units that make up this body. The units are returned as a PatchingChain. The client can then manipulate the chain, adding and removing units, and the changes will be reflected in the body. Since a PatchingChain is returned the client need not worry about removing exception boundary units or otherwise corrupting the chain.
[中]返回组成此实体的单位链。这些单元作为修补链返回。然后,客户机可以操作链,添加和删除单元,更改将反映在主体中。由于PatchingChain被返回,客户机不必担心删除异常边界单元或以其他方式损坏该链。
