Re: [p2-dev] @noimplement and @noextend annotation of IQuery
|
It would be interesting to understand what types of queries cannot be expressed with the _expression_ Language.
In the worst case you could write an _expression_ query that returns all the results and iterate through the list choosing the ones you want. This is obviously less than optimal though.

I know p2 want developers using _expression_ query instead of directly
implementing IQuery interface.
However some query conditions can't be translated to _expression_. So we
have to implement the IQuery interface. Those two annotation might let
PDE warn the concrete class illegally.
I think it's a pervasive case, the _expression_ can't cover all what users
want to compare. And directly implementing IQuery give us the biggest
capability.
