提取类使用AST解析器实现的接口 [英] extract interface that a class implementing using AST parser

问题描述

我正在使用AST解析器编译项目源。我可以通过什么方式提取类层次结构信息，即它是实现任何接口还是从另一个类扩展？

I am compiling a project source using AST parser. In what way i can extract class hierarchy infromation, that is whether it is implementing any interface or extends from another class?

推荐答案

您可以访问 TypeDeclaration 节点并从中获取类型绑定。

You can visit the TypeDeclaration node and get the type binding from it.

ITypeBinding typeBind = typDec.resolveBinding();

然后可以按如下方式获取超类和已实现的接口：

You can then get the super class and implemented interfaces as follows:

public boolean visit(TypeDeclaration typeDeclaration) {

        ITypeBinding typeBind = typeDeclaration.resolveBinding();
        ITypeBinding superTypeBind = typeBind.getSuperclass();
        ITypeBinding[] interfaceBinds = typeBind.getInterfaces();      

        return true;
}
