基于 AST 的 Eclipse 搜索 [英] AST-based search for Eclipse

问题描述

是否有 Eclipse 插件可以让您根据项目文件的 Java AST(抽象语法树)进行搜索?Java 搜索"功能似乎不包括以下情况:

Is there a plug-in for Eclipse that lets you search based on the Java AST (Abstract Syntax Tree) of your project files? The "Java Search" feature doesn't seem to cover cases like:

获取所有类中声明为'X'类型的所有字段"

"Get me all the fields declared as type 'X' in all classes"

我可以想象基于 AST 的搜索会带来更多可能性，但我什至不知道这样的插件是否具有实际性能.

I can imagine many more possibilities that would open up with an AST-based search, but I don't even know if such a plug-in would have practical performance.

更新:正如下面 Kevin 所指出的，Java 搜索功能确实涵盖了我提到的用例.我仍然很好奇是否有人编写了允许任意类型的 AST 搜索的插件，例如.获取所有字符串连接"(带有 + 运算符和 StringLiteral 操作数的 InfixExpression)

Update: As pointed out by Kevin below, the Java Search feature does cover the use case I mentioned. I'm still curious though about whether or not someone has written a plug-in that allows any arbitrary kind of AST search, ex. "Get all string concatenations" (InfixExpression with + operator and StringLiteral operand)

推荐答案

获取所有声明为类型的字段所有课程中的X"

Get me all the fields declared as type 'X' in all classes

我不知道您还有什么想法，但我相信您可以通过执行以下操作来完成此特定搜索:

I don't know what else you had in mind but I believe you can accomplish this specific search by doing the following:

• 打开类型 X (Ctrl-Shift-T)
• 突出显示类名
• Ctrl-H 搜索
• 搜索类型/匹配位置 -> 字段类型
