Along with my Xtext/XBase DSLs, i have Java classes which can be accessed by my DSL's XExpression.
The methods of my java classes are annotated using Java Annotations.
How can I find out the list of java classes available and its methods along with its respective annotations from Xtext.
Say, I used a generator where i need to print out the classes , methods in the classes with their annotations in a text file.How can I do this?

when i use this below code fragment , it was not printing me the java files as URIs.
But some how Xtext/XBase has the data indexed.

@Inject IContainer.Manager manager
 
def void printVisibleResources(Resource resource, IResourceDescriptions index) {
    val descr = index.getResourceDescription(resource.URI)
    for (visibleContainer : manager.getVisibleContainers(descr, index)) {
        for (visibleResourceDesc : visibleContainer.resourceDescriptions) {
            println(visibleResourceDesc.URI)
        }
    }
}

Hi,

this is not generally possible.

have a look at the classes IJvmTypeProvider - that does name lookup

and ITypesProposalProvider that is used for proposals
