Build AST Model Using Spoon when input project files are located in memory and not saved as files in disk
问题
我正在与Spoon Inria合作，用于解析和分析Java应用程序。目前，我正在使用以下代码创建输入项目模型。当项目文件保存在磁盘中时，此代码有效。
Launcher spoonAPI = new Launcher();spoonAPI.addInputResource(projectDirectory); // 项目根目录的路径spoonAPI.buildModel();CtModel ctModel = spoonAPI.getModel();
然而，目前我拥有Java文件（类）的内容存储在内存中，我不想将它们写入磁盘，因为这需要很长时间。
我想知道是否有一种方法可以使用Spoon将文件内容传递给解析器。例如，像下面的代码一样：
// Key是类的名称，Value是其内容Map<String, String> JavafileContents = new HashMap<String, String>();for (String filePath : JavafileContents.keySet()) {spoonAPI.parse(JavafileContents.get(filePath));}CtModel ctModel = spoonAPI.getModel(); // 提取的模型应包含所有已解析的文件。
类似于JDT提供的类似解决方案。
ASTParser parser = ASTParser.newParser(AST.JLS14);parser.setSource(javaFileContents.get(filePath).toCharArray());CompilationUnit compilationUnit = (CompilationUnit) parser.createAST(null);

I am working with Spoon Inria to parse and analyze Java applications. Currently, I am using the below code to create input project model. This code works when project files are saved in the disk.
Launcher spoonAPI = new Launcher();spoonAPI.addInputResource(projectDirectory); //The path to the project root directoryspoonAPI.buildModel();CtModel ctModel = spoonAPI.getModel();
However, currently I have contents of Java files (classes) in the memory and I do not want to write them in the disk as it takes ages.
I was wondering if there is a way using Spoon that I can pass file contents to the parser. For example, a code as below.
//Key is name of class and value is its contentMap<String, String> JavafileContents= new HashMap<String, String>();for (String filePath : JavafileContents.keySet()) {spoonAPI.parse(JavafileContents.get(filePath ));}CtModel ctModel = spoonAPI.getModel(); //The extracted model should contains all parsed files.
Like a similar solution provided in JDT.
ASTParser parser = ASTParser.newParser(AST.JLS14);parser.setSource(javaFileContents.get(filePath).toCharArray());CompilationUnit compilationUnit = (CompilationUnit)parser.createAST(null);

我也在寻找这个功能，我发现下面的代码可能符合您的要求。
import spoon.support.compiler.VirtualFile;...public static CtClass<?> parseClass(String code) {Launcher launcher = new Launcher();launcher.addInputResource(new VirtualFile(code));launcher.getEnvironment().setNoClasspath(true);launcher.getEnvironment().setAutoImports(true);...
源代码位于 https://github.com/INRIA/spoon/blob/spoon-core-8.2.0/src/main/java/spoon/Launcher.java#L856。
或者，您也可以使用像 createCodeSnippetStatement 这样的 API
Factory factory = new Launcher().createFactory();CtStatement tmpStmt = factory.Code().createCodeSnippetStatement(code);
选择使用哪种 API 取决于您的代码片段的类型（例如，表达式或语句）。

I'm also looking for the functionality, I found the following code may meet your requirement.
import spoon.support.compiler.VirtualFile;...public static CtClass<?> parseClass(String code) {Launcher launcher = new Launcher();launcher.addInputResource(new VirtualFile(code));launcher.getEnvironment().setNoClasspath(true);launcher.getEnvironment().setAutoImports(true);...
The source is https://github.com/INRIA/spoon/blob/spoon-core-8.2.0/src/main/java/spoon/Launcher.java#L856.
Alternatively, one can use APIs like createCodeSnippetStatement
Factory factory = new Launcher().createFactory();CtStatement tmpStmt = factory.Code().createCodeSnippetStatement(code);
The way of choosing an API depends on the type of your code snippet (e.g., expression or statement).
