You have to determine the class of a ConditionalElement (this is an
interface for things common to Pattern, Group and Accumulate. If it is a
Pattern, you proceed by iterating over the tests, either thos in a
particular slot or over all.
Add this after your println:
if( e instanceof Pattern ){
Pattern p = (Pattern)e;
Iterator<?> titer = p.getTests( );
while( titer.hasNext() ){
Object o = titer.next();
System.out.println( "test: " + o.toString() );
}
}
