Hello,

will be nice to be able to configure some options for this feature ala gson.

on gson lib, you are able to 
1) write custom serializer (can be done imps JSONAware so its ok)
2) write custom exclusion strategy: method get invoked per each field, and must 
return true/false to skip/keep the field ie:
    private class MyExclusionStrategy implements ExclusionStrategy {

        public boolean shouldSkipClass(Class<?> clazz) {
            return false;
        }

        public boolean shouldSkipField(FieldAttributes f) {
            String cn = (f.getDeclaringClass().getCanonicalName() + '.' + f.getName());
            for (String s : skip)
                if (cn.contains(s)) return true;
            return false;
        }
    }
in this way, we can build a macro serializer object, that can be configured 
on-the-fly with unwanted fields.

3) probably the most important feature, be able to serializer 
private/protected/transient fields (and toggle between them). on GSON by 
default, you get the full load of all fields per each class, then you can
                .excludeFieldsWithModifiers(java.lang.reflect.Modifier.TRANSIENT)

to remove some modifiers from the serialization. This will add a great value 
imho, sometimes is useful to serialize private/package_protected fields 
(transient should be keep off, the meaning of transient is exactly 'don't 
serialize it please') but, if you think about keep the state of a bean, a 
private VAR must be serialized for sure

such a feature implementation had been Start using

net.minidev.asm.FieldFilter;

this feature is not public for the moment and only will be available in 
json-smart 2.X

I think I have to add a JsonParserFactory to complete this feature.
