closepublic void close()Description copied from interface:ResultIteratorCloses ResultIterator and associated ResultSet. This method must be called explicitly when the user is finished processing the records. Otherwise unused database resources will not be released properly.- Specified by:
- closein interface- AutoCloseable
- Specified by:
- closein interface- ResultIterator<T>
 
- 
allRowsDescription copied from interface:ResultIteratorReturns all yet unread rows from ResultSet without closing it.- Specified by:
- allRowsin interface- ResultIterator<T>
- Since:
- 3.0
 
- 
hasNextRowpublic boolean hasNextRow()Description copied from interface:ResultIteratorReturns true if there is at least one more record that can be read from the iterator.- Specified by:
- hasNextRowin interface- ResultIterator<T>
 
- 
nextRowDescription copied from interface:ResultIteratorReturns the next result row that is, depending on the query, may be a scalar value, a DataRow, or an Object[] array containing a mix of scalars and DataRows.- Specified by:
- nextRowin interface- ResultIterator<T>
- Since:
- 3.0
 
- 
skipRowpublic void skipRow()Description copied from interface:ResultIteratorGoes past current row. If the row is not needed, this may save some time on data conversion.- Specified by:
- skipRowin interface- ResultIterator<T>
- Since:
- 3.0
