Class UimaResultSetIterator

java.lang.Object

org.deeplearning4j.text.sentenceiterator.BasicResultSetIterator

org.deeplearning4j.nlp.uima.sentenceiterator.UimaResultSetIterator

All Implemented Interfaces:

SentenceIterator

public class UimaResultSetIterator
extends BasicResultSetIterator

Iterates over and returns sentences based on the passed in analysis engine Database version of UimaSentenceIterator based off Adam Gibson's UimaSentenceIterator but extends BasicResultSetIterator 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);
