Interface ExceptionListener

public interface ExceptionListener

The exception listener interface must be implemented by types which want to get informed about unexpected exceptions within PriDE API operations. Every Database objects has the ExceptionListener associated which is set as default listener in the DatabaseFactory. You can register your own ExceptinListener by calling setDefaultExceptionListener.
