        public Object invoke(Connection conn, ResultSet rs, Pojo pojo, Statement stmt) throws SQLException {
            Object value = lnk.getCallback().invoke(conn, rs, pojo, stmt);
            lnk.setValue(obj, value);
            return value;
        }
    });

Example 2 with PojoCallback

use of org.nutz.dao.sql.PojoCallback in project nutz by nutzam.

the class DoInsertLinkVisitor method visit.

public void visit(final Object obj, final LinkField lnk) {
    final Object value = lnk.getValue(obj);
    if (Lang.length(value) == 0)
        return;
    // 从宿主对象更新关联对象
    opt.add(Pojos.createRun(new PojoCallback() {

        public Object invoke(Connection conn, ResultSet rs, Pojo pojo, Statement stmt) throws SQLException {
            lnk.updateLinkedField(obj, value);
            return pojo.getOperatingObject();
        }
    }).setOperatingObject(obj));
    // 为其循环生成插入语句 : holder.getEntityBy 会考虑到集合和数组的情况的
    final Entity<?> en = lnk.getLinkedEntity();
    Lang.each(value, new Each<Object>() {

        public void invoke(int i, Object ele, int length) throws ExitLoop, LoopException {
            if (ele == null)
                throw new NullPointerException("null ele in linked field!!");
            // 执行插入
            opt.addInsert(en, ele);
            // 更新字段
            opt.add(Pojos.createRun(new PojoCallback() {

                public Object invoke(Connection conn, ResultSet rs, Pojo pojo, Statement stmt) throws SQLException {
                    lnk.saveLinkedField(obj, pojo.getOperatingObject());
                    return pojo.getOperatingObject();
                }
            }).setOperatingObject(ele));
        }
