Example 1 with EventData

use of com.vaadin.flow.component.EventData in project flow by vaadin.

the class PolymerServerEventHandlers method getParameters.

private String[] getParameters(Method method) {
    List<String> result = new ArrayList<>();
    for (Parameter parameter : method.getParameters()) {
        EventData eventData = parameter.getAnnotation(EventData.class);
        if (eventData != null) {
            result.add(eventData.value());
        }
        if (ReflectTools.hasAnnotation(parameter, REPEAT_INDEX_FQN)) {
            result.add(REPEAT_INDEX_VALUE);
        }
        Optional<Annotation> annotation = ReflectTools.getAnnotation(parameter, MODEL_ITEM_FQN);
        if (annotation.isPresent()) {
            result.add(ReflectTools.getAnnotationMethodValue(annotation.get(), VALUE).toString());
        }
    }
    return result.toArray(new String[result.size()]);
