I can't quite comprehend how to best go about implementing a Builder pattern for the following generics hierarchy.
Base class,
@lombok.Data
public class Node<T> {
private T data;
private String source;
}
Child class,
@lombok.Data
public class MyNode extends Node<MyNode> {
private String firstDummy;
private String secondDummy;
}
Is there anyway to apply an anonymous builder class to the parent and extend it in the child class ?
Updated
If i have an anonymous builder like so for the Parent,
public class Node<T> {
private T data;
private final String source;
public static abstract class Builder<S extends Node> {
private String source;
public Builder<S> withSource(String source) {
this.source = source;
return this;
}
public abstract S build();
}
public static Builder<?> builder() {
return new Builder<Node>() {
@Override
public Node build() {
return new Node(this);
}
};
}
protected Node(Builder<?> builder) {
this.source = builder.source;
}
}
How do I then implement the builder for T in Node class ?
