Class ResultSetCursor

java.lang.Object
  |
  +--xxl.relational.ResultSetCursor
public class ResultSetCursor
extends java.lang.Object
implements Cursor

This class serves a ResultSet as a Cursor.

When the method next of this Cursor is called, a Tuple will be created from the underlying ResultSet and this Tuple will be returned.
This Cursor does not support peek, reset, remove or update.

One can specify, which kind of tuple implementation should be used here.

Example: 


	new ResultSetCursor(resultSet, ArrayTuple.FACTORY_METHOD);
Now the tuples of resultSet are served as ArrayTuples.

If nothing is specified, the linked list implementation will be used.

Example: 


	new ResultSetCursor(resultSet);
Now the tuples of resultSet are served as ListTuples.
