Thanks for the clarification :)
So there isn’t a way to get only the bundle descriptions that has a resolver 
error. You have to check them all.

The isResolved() method does not indicate that every bundle in the state is in 
the resolved state. As the javadoc states it only indicates that the State has 
not been modified since the last call to one of the State.resolve methods. This 
method is intended to indicate that the State needs a resolve operation done on 
it because it has pending changes that could effect the resolution state when 
one of the resolve methods is called.

Perhaps I should add that last sentence to the javadoc ;-)

It sounds like Virgo is doing the correct thing by looking for resolver errors 
for unresolved BundleDescriptions after performing a resolve operation.

[equinox-dev] equinox state and resolver

________________________________



Hi,

I was playing around with the Equinox resolver and state and observed something 
that confused me.

I get a state object from PlatformAdmin and add some bundle descriptions that I 
know won’t be able to resolve – for example they trigger a “uses” conflict.
I call resolve and after that isResolved(), which returns true.
If I go through the bundle descriptions in the state and check them I’ll be 
able to retrieve the resolver error for the uses conflict and that particular 
bundle description will return false for its isResolved() method.
I found that strange so I checked the javadoc for State’s isResolved method and 
found it “Returns true if there have been no modifications to this state since 
the last time resolve() was called.”.
This puzzled me even more, after all I included some descriptions in that State.

In Virgo for the quasi resolve to catch resolver errors early, we check the 
bundles descriptions for resolver errors and don’t call the isResolved method 
of the State, which works fine.
But it made me curious about how the State is expected to work and in order to 
get a resolution result which is the best approach.
Can you share some technical background? :)

Best Regards
Borislav
