Problème avec SearchEngine
Bonjour.
Voici mon problème.
Je suis en train de mettre en place une fonction de recherche grâce au SearchEngine JAVA.
Voici le code relatif à la création de mon SearchEngine :
Code:
1
2
3
4
5
6
7
8
9
| // Create search scope
SearchPattern my_pattern = SearchPattern.createPattern("int", JavaSearchConstants.DECLARATIONS, IJavaSearchConstants.ALL_OCCURRENCES, SearchPattern.R_PATTERN_MATCH);
IJavaSearchScope my_scope = SearchEngine.createWorkspaceScope();
SearchRequestor my_requestor = new MySearchRequestor();
SearchEngine searchEngine = new SearchEngine();
searchEngine.search(my_pattern, new SearchParticipant[] {SearchEngine.getDefaultSearchParticipant()}, my_scope, my_requestor, null); |
Et voici le code de la fonction acceptSearchMatch de ma classe MySearchRequestor qui étend SearchRequestor comme exigé qui me envoie un message à chaque fois qu'une occurence de ma recherche est trouvée :
Code:
1
2
3
| public void acceptSearchMatch(SearchMatch searchMatch) throws CoreException {
sample.showMessage("référence trouvée..." + myObject.getClass());
} |
Cependant après plusieurs essais en changeant les critères de recherches, j'ai le message d'erreurs suivant :

J'ai l'impression que ce message n'apparait que quand ma recherche trouve un élément qui correspond à mes critères et qu'il n'apparaît pas quand ma recherche ne trouve rien.
Si quelqu'un avait de quoi me faire sortir de l'impasse...
D'avance merci
