Cursor (mybatis 3.5.15 API)

All Superinterfaces:

AutoCloseable, Closeable, Iterable<T>

All Known Implementing Classes:

DefaultCursor
```
public interface Cursor<T>
extends Closeable, Iterable<T>
```
Cursor contract to handle fetching items lazily using an Iterator. Cursors are a perfect fit to handle millions of items queries that would not normally fit in memory. If you use collections in resultMaps then cursor SQL queries must be ordered (resultOrdered="true") using the id columns of the resultMap.
