数据类型
说明
rowType
输出
String
返回更新策略类型，该类型是以下值之一：
  • DELETE
  • INSERT
  • REJECT
  • UPDATE
可以将 getInRowType 方法添加到
输入行
代码输入选项卡上的 Java 代码中。
可以在配置为设置更新策略的主动转换中使用 getInRowType 方法。 如果在未配置为设置更新策略的主动转换中调用此方法，则
会话
将生成错误。
使用以下 Java 代码可完成以下操作：
  • 将当前输入行类型传播到输出行。
  • 如果 input1 输入端口的值大于 100，则将输出行类型设置为 DELETE。 
// Set the value of the output port.
output1 = input1;
// Get and set the row type.
String rowType = getInRowType();
setOutRowType(rowType);
// Set row type to DELETE if the output port value is > 100.
if(input1 > 100
     setOutRowType(DELETE);
