Hi Andrea,
Your hitting on some definite issues with the api... and ones i am
ashamed to say i have hacked around in the past :(. So here is what I
think is needed:
1. A way to do only *safe* vs *lax* conversions
2. A way to prioritize or sort factories
So i would recommend the following:
1. Add a method to Converter"
boolean isSafe();
Then we also add an additional method to Converters called convert( ...,
boolean safe ), which would only allow safe coverters to execute.
2. Add a method to ConverterFactory:
int getPriority();
And then sort on it when the converter factories are loaded.
What do folks think?
