Get a list of methods from a class which can be called from java source code

Question

I need a way to get a list of all methods of a java class which could be called from a java file. I know that I can use Class.getMethods, but that does not work in some situations like I need it:

public interface IField<T> {
    public void setValue(T value);
}

public class Field implements IField<String> {
    private String value;

    @Override
    public void setValue(String value) {
        this.value = value;
    }
}

Calling Field.class.getMethods() contains to setValue methods, but only the one with the String parameter is allowed to be called from a java source file.

Just remove the one with the "less specific" parameter is also not a solution becasue there might be situations like this:

public abstract class AbstractBean {
    private Object value;

    public void setValue(Object value) {
        this.value = value;
    }
}

public class Field extends AbstractBean {
    private Integer value;

    public void setValue(Integer value) {
        this.value = value;
    };
}

where both setValue methods are ok to be called.

you may aswell want to loop through the superclasses of Field. — SomeJavaGuy

After some more research I found this article on type erasure. So I have to filter out the bridge methods via Method.isBridge()
