eclipse - 如何从给定包中获取所有类的列表

Question

我有一个 Eclipse bundle ，并且想要获取该 bundle 中所有类的列表。

我该怎么做？

Answer 1

bundle 中的类的名称将位于最后的 classNameOfCurrentBundle 列表中:

BundleWiring bundleWiring = bundle.adapt(BundleWiring.class);
// Getting all the class files (also from imported packages)
Collection<String> resources = bundleWiring.listResources("/", "*.class", BundleWiring.LISTRESOURCES_RECURSE);

List<String> classNamesOfCurrentBundle = new ArrayList<String>();
for (String resource : resources) {
    URL localResource = bundle.getEntry(resource);
    // Bundle.getEntry() returns null if the resource is not located in the specific bundle
    if (localResource != null) {
        String className = resource.replaceAll("/", ".");
        classNamesOfCurrentBundle.add(className);
    }
}

将类名转换为类类型:

bundle.loadClass(className);
