[Wicket-develop] i am a bit playing with the converter interface.

[Johan Compagner]

Hi,

first currently we have IConverter and ITypeConverter , i want to combine those 2 to be one interface
And then a converter must be easy to make but also to understand.

So i can do this:

IConverter.convertToObject (String, Class)
IConverter.convertToString(Object)

Then writing a DateConverter is pretty simple, you have one SimpleDateFormat (or more per locale)
and then in toObject you do parse and in toString you do format

The thing is we loose a bit of the more "generic" nature we have now
because in the current setup we could do:

conveter.convert(new Double(10), Integer.class) to convert from a double to a integer.
Do we need this? We could make:

IConverter.convertObject(Object, Class) instead of IConverter.convertToObject(String, Class)
besides to convertToString.

But that would complicate converters again.

That Class param can be ignored by a Converter impl (or it could check if it was the type for which this converter is build.)
But having that class param there then it is possible to make a compound converter and only have one interface
so that you can much easier make youre converter for a specific textfield.
