Hi Niall,
first off, thanks for the great library. But I'm having trouble fitting
the following together:
package com.mycompany.simpletest;
import org.simpleframework.xml.Element;
import org.simpleframework.xml.Root;
@Root(name = "pair")
public class Pair<A, B> {
@Element
private final A first;
@Element
private final B second;
public Pair(A first, B second) {
this.first = first;
this.second = second;
}
public A getFirst() { return first; }
public B getSecond() { return second; }
}
------------------
package com.mycompany.simpletest;
import java.util.ArrayList;
import java.util.List;
import org.simpleframework.xml.Element;
import org.simpleframework.xml.ElementList;
import org.simpleframework.xml.Root;
@Root(name = "test")
public class Test {
@Root(name = "element1")
public class Info {
@Element
private String name;
public Info(String name) {
this.name = name;
}
}
@ElementList(name = "list")
private List<Pair<Info, Info>> list;
public Test() {
list = new ArrayList<>();
}
public void add(String s1, String s2) {
Info i1 = new Info(s1);
Info i2 = new Info(s2);
Pair<Info, Info> p = new Pair<>(i1, i2);
list.add(p);
}
}
------------------
package com.mycompany.simpletest;
import java.io.FileOutputStream;
import org.simpleframework.xml.Serializer;
import org.simpleframework.xml.convert.AnnotationStrategy;
import org.simpleframework.xml.core.Persister;
import org.simpleframework.xml.strategy.Strategy;
public class SimpleTest {
public static void main(String[] args) {
Test t1 = new Test();
t1.add("a", "b");
t1.add("b", "c");
try {
FileOutputStream out = new FileOutputStream("test.xml");
Strategy strategy = new AnnotationStrategy();
Serializer serializer = new Persister(strategy);
serializer.write(t1, out);
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
And this is the result:

You cannot construct a non static inner class through reflection. For the constructors also you must specify the names
Pair(@Element(name="first") A first, @Element(name="second") B second)

Hi,
could you please help me get this working? I really do not know what is
wrong. I haven't had the time to look into the simple sources yet...

I think I mentioned that non-static inners cannot be instantiated via reflection, it has an implicit "this"...
