Postgresql's inet type, ipv4/ipv6/mac

Hi!

I've failed to find (google and this forum) a working example where Hibernate maps the postgresql type INET. Have anyone seen work being made on this anywhere, 'cause I've failed to find that as well.

The way to do it would of course be to create a new Type, but without looking much into it, that seems to be a too big a challenge to me.

So, currently, what I'm looking at is to map the bean properties as Strings and then implement Lifecycle to set up proper Java classes in onLoad, and convert them back to string in onUpdate and onSave.

Is there a better way to do this? Is there something particular I should consider regarding the Lifecycle-approach?

Thanks in advance

Implementing a custom UserType for this is actually very easy. This is really the way to go here.

Oh, I intend to use the MACADDR type and INET, but only for IPv4Address - no ranges and no IPv6. (I hope someone else have provided a better solution when I need IPv6 support in the application.)

Ok, I'll give it a try then. Thanks.

onSave and onUpdate are actually called dring the first usage of save or update.

Code:

Object o = session.load(...);
session.update(o);

won't call onUpdate().

Consider using a custom type. There is a sample in the wiki area

A good sample is for example this one: http://www.hibernate.org/76.html
