Examples of org.onebusaway.exceptions.ServiceException

org.onebusaway.exceptions.ServiceException
A base exception type that is used by many OneBusAway service methods. I decided to make this base exception a sub-class of {@link RuntimeException}, which means that you do no have to explicitly wrap calls to methods that throw {@link ServiceException} with catch or with throws. There is a lot ofdebate about that behavior in the Java community. Generally speaking, if errors are non-recoverable, the convention is to make them a runtime exception. However, there are definitely a number of uses of {@link ServiceException} and its subclasses that are recoverable. Perhapssome refactoring is in order? @author bdferris
