We have code that was created in Eclipse Galileo. I need to upgrade the Eclipse to the latest version. I run into an issue that the interface IObservableValue changed definition to IObservableValue<T>
I'm looking for new example how the EMF databinding should be defined but can't find any information
My code is simple:
public boolean doDataBinding(EditingDomain domain, EObject input) {
binding = new EMFDataBindingContext();
IWidgetValueProperty<Text, String> prop = WidgetProperties.text(SWT.Modify);
IEMFValueProperty value = EMFEditProperties.value(domain, fldFeature);
IObservableValue<?> ob = value.observe(input);
binding.bindValue(prop.observeDelayed(FIELD_INPUT_DELAY, txtControl), ob);
return false;
}
The warning I get on the code "value.observe(input)" is:
Type safety: The method observe(Object) belongs to the raw type IValueProperty. References to generic type IValueProperty<S,T> should be parameterized
How do I do that???
Where can I find sample code that will help me do databinding for all types of widgets?
Thanks
Yigal

Hi
Presumably your code works, so Java is 'happy' with the partial type information. The easiest approach is to add e.g. @SuppressWarnings("rawtypes") perhaps to individual declarations, perhaps to methods / classes / projects.
If some parameters are already defined then you need to go along with them, otherwise <?> or <Object> will probably do.
Ultimately genetics enable you to write safer code so its best to use them rather than fight them. As Ed Merks writes, helper methods can help.I have a variety of XXXUtil classes for such purposes.
