CLang 3.5 LibTooling:获取clang :: VarDecl中变量的文件名 [英] CLang 3.5 LibTooling: getting file name of a variable in clang::VarDecl
问题描述
我有一个 clang :: VarDecl
对象。我想获取变量的文件名/位置(至少如果它们是全局的)。我也通过一个问题: -
I am having a clang::VarDecl
object. I want to fetch the file name/location of the variable (at least if they are global). I also skimmed through a question:-
但我想这不是关于文件名哪些变量被声明。
我还提到了
But I guess it is not about file name in which variables are declared. I also referred to
http://clang.llvm.org/doxygen/classclang_1_1SourceLocation.html
没有可能返回文件名的任何函数。
There isn't any function which may return file name. Can anybody tell me how to get it?
推荐答案
你应该使用 SourceManager
获取 SourceLocation
中的具体数据。具体来说,请查看 SourceManager :: getFilename(SourceLocation) 方法
。
You're supposed to use SourceManager
to get concrete data out of a SourceLocation
. In particular, take a look at the SourceManager::getFilename(SourceLocation)
method.
您可以通过以下方式获取 SourceManager
使用 CompilerInstance :: getSourceManager
。
You can get an instance of a SourceManager
by using CompilerInstance::getSourceManager
.
