Loop Embedded Objects¶
You can use Loop embedded objects to obtain data from the For Each dataset.
Property¶
Property | Type | Description |
|---|---|---|
dataArray | String | Dataset input by the For Each node. It is a two-dimensional array. |
current | String | Data row traversed by the For Each node. It is a one-dimensional array. |
offset | Int | Current offset of the For Each node, starting from 0. Loop.dataArray[Loop.offset] = Loop.current. |
Example¶
The EL expression for the Foreach operator to cyclically obtain the first column of the output (a two-dimensional array) of the previous node is as follows:
#{Loop.current[0]}
