[news.eclipse.platform] Re: Obtaining classes/types of a project

[Jacek Pospychala <jacek.pospychala@xxxxxxxxxx>]

Paul,

i've been thinking of using JDT search engine - it can find classes very 
fast, without iterating over whole project. But i got stuck with 
defining the search query. We basically want to know of all types 
definitions in a project, but search engine doesn't make a big 
distinction between classes defined in source folders and found deeply 
in classpath, so user would have to find out all the source folders and 
use only them as a search scope.
The best place to start out with search are SearchPattern and 
SearchEngine classes from jdt.core.

Another question is how to switch from classes to all their hierarchies. 
It's again easy to search, but may be not very effective if we want it 
for all classes in project. Ryan, could you give us some more details, 
how do you want to use the list of classes with their types hierarchy?
