Example 1 with CreoleListener

use of gate.event.CreoleListener in project gate-core by GateNLP.

the class AnnotationEditor method initData.

protected void initData() {
    schemasByType = new HashMap<String, AnnotationSchema>();
    java.util.List<LanguageResource> schemas = Gate.getCreoleRegister().getLrInstances("gate.creole.AnnotationSchema");
    for (Iterator<LanguageResource> schIter = schemas.iterator(); schIter.hasNext(); ) {
        AnnotationSchema aSchema = (AnnotationSchema) schIter.next();
        schemasByType.put(aSchema.getAnnotationName(), aSchema);
    }
    CreoleListener creoleListener = new CreoleListener() {

        @Override
        public void resourceLoaded(CreoleEvent e) {
