public class CursorSelectOption {
    // ===================================================================================
    //                                                                           Attribute
    //                                                                           =========
    protected boolean _byPaging;
    protected boolean _orderByPK;
    protected int _pageSize;
    // ===================================================================================
    //                                                                           by Paging
    //                                                                           =========
    
Do cursor select by paging ordering by PK.
Consistent-read is not perfect.
You might select records at second or more select that are not target when the first select.

Parameters:
pageSize The size of one page. (NotMinus, NotZero)
Returns:
this. (NotNull)
    public CursorSelectOption byPagingOrderByPK(int pageSize) {
         = true;
         = true;
         = pageSize;
        return this;
    }

    
Do cursor select by paging simply.
Consistent-read is not guaranteed.
You might select duplicate records or cannot select required records, so you should save consistent-read by DBMS settings, e.g. MySQL's RepeatableRead.

Deprecated:
Consistent-read is not guaranteed so you should use this carefully.
Parameters:
pageSize The size of one page. (NotMinus, NotZero)
Returns:
this. (NotNull)
    public CursorSelectOption byPagingSimply(int pageSize) {
         = true;
         = false;
         = pageSize;
        return this;
