Annotation

Annotations are used to control the behavior of jCloak. You need to include the annotations in your project.

JCloakEntrypoint

The JCloakEntrypoint is the most important annotation. Without it’s existance, jCloak won’t work. It should be used on the class that is being loaded first. This is typically the Main class.

@JCloakEntrypoint
public class Main {

    public static void main(String[] args) {
        new TestClass();
    }
}

JCloakLoaded

The JCloakLoaded annotation marks the class for removal and thus hides it from the jar.

@JCloakLoaded
public class TestClass {

    public TestClass() {
        System.out.println("Hello World");
    }
}

Native Implementation

You can also create a native dummy class which has native methods to fake a native implementation. This is especially usefull when you want to expose api endpoints while hiding their implementation.

This can be done by setting the value of the annotation to NATIVE_DUMMY

@JCloakLoaded(NATIVE_DUMMY)
public class TestClass {

    public TestClass() {
        System.out.println("Hello World");
    }
}

The result will look like this:

public class TestClass {

    public native TestClass();

}
