Can't figure out what lazy-loading policy NHibernate uses

Can somebody te开发者_如何学Cll me what lazy-loading policy NHibernate uses? Various sources provides contradictory information - this one says that NHibernate doesn't provide lazy-loading for properties, and NHibernate in Action read that lazy-fetching are on by default. Am I missing something?

I am not an expert but I think that the book means lazy loading of collection properties. As for other properties nhibernate does support them but it might not be released yet: NHibernate new feature: Lazy Properties
