Description Thomas Watson CLA 2011-05-25 08:35:59 EDT 
In bug 346979 we needed to generate a filter from a set of arbitrary attributes.  It became evident that we need some kind of filter builder to make such code more simple.  Some other things to note:

- VersionRange is not completely correct with respect to open ranges (i.e. >=1.0).  It uses max.max.max as the absolute maximum version, but max.max.max.qualifier > max.max.max.
- VersionRange could add a method to get a filter string that represents the range

Move all 3.8 bugs to Juno.
Comment 2 Thomas Watson CLA 2011-08-04 16:10:40 EDT 
There is a proposal in OSGi to add a VersionRange class to the org.osgi.framework package.  This VersionRange class may contain a toFilterString() method.  If this happens then we can consider using that method to generate the filter string.  We will also consider making the Equinox VersionRange extend the osgi VersionRange.
Comment 3 Thomas Watson CLA 2012-02-29 12:15:27 EST 
This is no longer valid.  The OSGi VersionRange class now provides the method we need to create a filter for version ranges.
