Hi,
I've a big problem with generics in GWT. I'm making a generic utility
to set a filter in a collection of data. I'd like to have a class
Filter with an attribute value that is the type that the user set:
public class Filter <T> implements Serializable{
private T value;
}
The problem is that GWT compiler raise an error beacuse the type T is
not Serializable. Another solution doesn't work:
public class Filter <T extends Serializable> implements Serializable{
private T value;
}
beacusa the type T can either implements or extends serializable.
So the only solution that I've think is to create a wrapper class
(that implements interface MyType) for each type that the attribute
value can be obtain (String,Date,Integer) and so the class Filter
became:
public class Filter <T extends MyType & Serializable> implements
Serializable{
private T value;
}
But I dont' like this solution.
Can someone post some ideas??
Thanks
Regards
