Class BasicResultSetIterator

java.lang.Object

org.deeplearning4j.text.sentenceiterator.BasicResultSetIterator

All Implemented Interfaces:

SentenceIterator

public class BasicResultSetIterator
extends Object
implements SentenceIterator

Primitive iterator over a SQL ResultSet Please note: for reset functionality, the underlying JDBC ResultSet must not be of TYPE_FORWARD_ONLY To achieve this using postgres you can make your query using: connection.prepareStatement(sql,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY); This class is designed in a similar fashion to org.deeplearning4j.text.sentenceiterator.BasicLineIterator
