Interface LineReader

  • All Known Implementing Classes:

    public interface LineReader
    When the Unmarshaller reads a text file, it reads it via a LineReader.
    Unless specified, the default implementation will be used, SimpleLineReader, which will read each line and pass it to the Unmarshaller
    Sometimes, text files contains lines you're not interested to, or you want to do some preprocessing before parsing them: in such cases, it's useful to provide your own implementation of LineReader
