Examples of RecordIterator

edu.stanford.nlp.io.RecordIterator
For reading files or input streams which are structured as records and fields (rows and columns). Each time you call next(), you get back the next record as a list of strings. You can specify the field delimiter (as a regular expression), how many fields to expect, and whether to filter lines containing the wrong number of fields. The iterator may be empty, if the file is empty. If there is an IOException when next() is called, it is caught silently, and null is returned (!). @author Bill MacCartney
no.priv.garshol.duke.RecordIterator
Special Iterator class for Record collections, in order to add some extra methods for resource management.
org.apache.drill.exec.ref.RecordIterator
org.apache.jackrabbit.core.journal.RecordIterator
RecordIterator interface.
org.archive.wayback.util.flatfile.RecordIterator
Iterator that returns sequential lines from a file. @author brad @version $Date: 2007-07-25 01:35:07 +0100 (Wed, 25 Jul 2007) $, $Revision: 1873 $
org.ofbiz.datafile.RecordIterator
Record Iterator for reading large files Note: this is a memory intensive and will not handle files that exceed memory.
org.openrdf.sail.nativerdf.btree.RecordIterator
An iterator that iterates over records, for example those in a BTree. @see BTree @author Arjohn Kampman
org.prevayler.demos.scalability.RecordIterator
Generates Record objects with ids from 0 to numberOfRecords - 1.
uk.ac.open.kmi.smartproducts.sesame.sail.btree.RecordIterator
