When creating a query using the Example object and the Hibernate Criteria API, you can create a query that excludes null values, which is the default, and you can also exclude zero values by calling the excludeZeroes() method. However, I wanted to exclude blank, non-null String objects, so I supposed excludeNone() would do the trick. Silly me.
The excludeNone() actually doesn't exclude null or zero-valued properties. Still, I found the 'double-negative' description of the method a little misleading.
