Hi Tomas,
thanks for your insights.
I am creating the ClasspathInfo object with a maven project root:
final ClassIndex classIndex =
ClasspathInfo.create(mvnPrj.getProjectDirectory()).getClassIndex();
where mvnPrj is a org.netbeans.modules.maven.NbMavenProjectImpl casted from
a org.netbeans.api.project.Project passed to the constructor of a class
annotated with @ProjectServiceProvider for maven project types.
I then query packages with:
Set<String> packageNames = classIndex.getPackageNames(filter, true,
EnumSet.allOf(ClassIndex.SearchScope.class));
where filter is a user typed text string, and later in the code for classes
in a given package with:
Set<ElementHandle<TypeElement>> types =
classIndex.getDeclaredTypes(typeFilter,
ClassIndex.NameKind.CASE_INSENSITIVE_PREFIX, Collections.singleton(new
SinglePackageScope(packageFilter)));
where typeFilter and packageFilter are substrings of user typed string.
To have more context the plugin project is on GitHub at
https://github.com/AlexFalappa/nb-springboot , the snippets above are
from here:
https://github.com/AlexFalappa/nb-springboot/blob/5a5867946a0c0d89a243b91559d163f43f0015dc/src/main/java/com/github/alexfalappa/nbspringboot/projects/service/impl/SpringBootServiceImpl.java#L252-L257
and here:
https://github.com/AlexFalappa/nb-springboot/blob/5a5867946a0c0d89a243b91559d163f43f0015dc/src/main/java/com/github/alexfalappa/nbspringboot/projects/service/impl/LoggerNameHintProvider.java#L57-L79
It seems I am doing everything right, yet I noticed getting back results
from all the maven projects currently opened in the IDE. I will double
check later at home.
Your explanation is already valuable however.
Regards,
Alex
