Class ResettableReaderIteratorFactory

java.lang.Object

edu.stanford.nlp.objectbank.ReaderIteratorFactory

edu.stanford.nlp.objectbank.ResettableReaderIteratorFactory

All Implemented Interfaces:

Iterable<Reader>

public class ResettableReaderIteratorFactory
extends ReaderIteratorFactory

Vends ReaderIterators which can always be rewound. Java's Readers cannot be reset, but this ReaderIteratorFactory allows resetting. It the input types are anything other than Readers, then it resets them in the obvious way. If the input is a Reader, then it's contents are saved to a tmp file (which is destroyed when the VM exits) which is then resettable.
