Retrieving mode (Basic|Advanced) of ADF query component

Question

I want to capture query component mode(Basic | Advanced) in processQuery event listener method for QueryEvent as below:

public void processQuery(QueryEvent queryEvent) { // Add event code here... QueryDescriptor qdesc = queryEvent.getDescriptor(); String searchName = qdesc.getName(); String queryMode =?

I tried to get this value from getUIHints() map using UIHINT_MODE key. but getUIHints() returns empty map.
