Interface HasNestedException

All Known Implementing Classes:

BadXMLException, NestedException, NestedRuntimeException

public interface HasNestedException

An interface implemented by some exceptions to indicate that they have an additional exception nested inside of them. This is very useful in order to be able to add extra information to an exception without losing the original information. For example:

       try
       {
            readFile(fileName);
       }
       catch (IOException x)
       {
            throw new NestedException("Error while reading "+fileName,x);
       }
