Loop Embedded Objects
You can use Loop embedded objects to obtain data from the For Each node.

Description |
Example |
|---|---|---|---|
dataArray |
String |
Loop.dataArray indicates the two-dimensional array defined in the dataset of the For Each node. Generally, the format is #{Loop.dataArray[0][0]} or #{Loop.dataArray[0][1]}. [0][0] indicates the first value in the first row of the array, and [0][1] indicates the second value in the first row, and so on. |
The value of Subjob Parameter for the For Each node indicates that the first value in the second row of the two-dimensional array in the dataset is always used in the For Each loop. #{Loop.dataArray[1][0]} |
current |
String |
For Each nodes process data in a dataset by row. Loop.current indicates a row of a two-dimensional array defined in the dataset of the For Each node. This row is a one-dimensional array. Generally, the format is similar to #{Loop.current[0]}, #{Loop.current[1]}, or others. [0] indicates the first value in the current row, [1] indicates the second value in the current row, and so on. |
The value of Subjob Parameter for the For Each node indicates that the second value in the traversed row of the two-dimensional array in the dataset is always used in the loop traversal of the For Each node. #{Loop.current[1]} |
offset |
Int |
Current offset of the For Each node, starting from 0. Loop.dataArray[Loop.offset] = Loop.current. |
Obtain the current offset of the For Each loop, that is, the number of traversals, starting from 0. #{Loop.offset} |
Example
To obtain the second value of a row that is being processed, use the following EL expression:
#{Loop.current[1]}
