Converters usage

Since 0.6, library is allowing to add converters. A converter is an object that is converting arguments from some type to other. Here is a simple example of a converter that is changing int arguments to save them as long:

static class IntToLongConverter implements ArgConverter<Integer, Long> {

    @Override
    public Long wrap(Integer toWrap) {
        return toWrap.longValue();
    }

    @Override
    public Integer unwrap(Long wrapped) {
        return wrapped.intValue();
    }
}

So if we define now @Arg int i; then it will be saved as long:

bundle.putLong(L_KEY, new IntToLongConverter().wrap(activity.i));

To use them, there must be added configuration annotation behind any class in project: (suggested is BaseActivity)

@ActivityStarterConfig(converters = { ParcelarArgConverter.class })

or in Kotlin

@ActivityStarterConfig(converters = arrayOf(ParcelarArgConverter::class))

This functionality should me mostly used to pass as an argument objects of not supported types. There are build-in converters:
