Class DBReader.DBReaderForwardIterator

java.lang.Object
org.apache.empire.db.DBReader.DBReaderIterator
org.apache.empire.db.DBReader.DBReaderForwardIterator
All Implemented Interfaces:
Iterator<DBRecordData>
Enclosing class:
DBReader
public class DBReader.DBReaderForwardIterator extends DBReader.DBReaderIterator
This is an iterator for forward only resultsets. There is an important limitation on this iterator: After calling hasNext() the caller may not use any functions on the current item any more. i.e. Example: while (i.hasNext()) { DBRecordData r = i.next(); Object o = r.getValue(0); // ok bool last = i.hasNext(); // ok Object o = r.getValue(0); // Illegal call! }
