In the following code snippet the inner classes Row and Cell do not
run through serialization. When it gets to "Verifying instantiability"
an exception is thrown, see below.
Everything does work if I take the inner classes out and make them
first class citizens
Code...........
public class DataModel implements Serializable,
Iterable<DataModel.Row> {
private static final long serialVersionUID =
5660038413002738627L;
public class Row implements Iterable<Cell>, Serializable {
private static final long serialVersionUID =
-8434488660727968577L;
public List<Cell> cells;
Row() {
//
}
public Cell get(int index) {
Cell result = cells.get(index);
if(result == null) {
result = new Cell();
cells.set(index, result);
}
return result;
}
public Iterator<Cell> iterator() {
return cells.iterator();
}
}
public class Cell implements Serializable {
private static final long serialVersionUID =
-2731510596752061219L;
private String contents;
Cell() {
//
}
public void setContents(Object contents) {
this.contents = contents == null ? null :
contents.toString();
}
public void setContents(int integer) {
this.contents = Integer.toString(integer);
}
public String getContents() {
return contents;
}
}
Exception.............
