Re: [Geotools-gt2-users] How do I find all the unique values of an attribute.

[Jody G. <jod...@gm...>]

There is a collection function that will figure out all the values for an
attribute (it may do a "full scan" of your data though depending on the
data store used).

For more information see the user manual:
