使用 Class 和 JInvocation.arg 的 Sun CodeModel

Sun CodeModel using Class with JInvocation.arg

我正在使用 sun 的代码模型 (2.4.1) 类 生成代码。如何将 Class 传递给 JInvocation.arg?我要生成的代码是:

JAXBContext jc;
jc = JAXBContext.newInstance(NaturalLanguageUsage.class);

我是运行的代码是:

JClass importJAXBContext = codeModel.directClass(javax.xml.bind.JAXBContext.class.toString());
JType typeJAXBContext = codeModel._ref(javax.xml.bind.JAXBContext.class);
JVar varJc = block.decl(typeJAXBContext, "jc");

JInvocation invokeJAXBContext = block.staticInvoke(importJAXBContext, "newInstance");
invokeJAXBContext.arg(??); // how do I pass NaturalLanguageUsage.class

我想生产什么:

JAXBContext jc;
jc = JAXBContext.newInstance(NaturalLanguageUsage.class);

甚至更好:

JAXBContext jc = JAXBContext.newInstance(NaturalLanguageUsage.class);
    JClass importJAXBContext = codeModel.ref(javax.xml.bind.JAXBContext.class);
    JVar varJc = block.decl(importJAXBContext, "jc");

    JClass naturalLangClassRef = codeModel.ref(NaturalLanguageUsage.class);

    JInvocation invokeJAXBContext = importJAXBContext.staticInvoke("newInstance");
    invokeJAXBContext.arg(naturalLangClassRef.dotclass());

    block.assign(varJc, invokeJAXBContext);

在一行中生成声明和赋值:

    JVar varJc = block.decl(importJAXBContext, "jc", invokeJAXBContext);
