Overview
Break needs to be used together with the For Each or While component to stop a loop. It can stop executing the loop statement even if the sequence is still in recursion or the loop condition is not false. When there is a nested loop, Break will jump out of the loop at the current layer and start to execute the next component.

Output
The message output by the component is as detailed below:
message Attribute |
Value |
| payload |
- In the For Each component, after the Break component is executed,
payload will inherit the payload of the component previous to For Each. - In the While component, after the Break component is executed,
payload will inherit the payload output by the component previous to Break.
|
| error |
Null. |
| attribute |
- In the For Each component, after the Break component is executed,
attribute will inherit the attribute output by the component previous to For Each. - In the While component, after the Break component is executed,
attribute will inherit the attribute output by the component previous to While.
|
| variable |
- In the For Each component, after the Break component is executed,
variable will be the variable output by the component previous to For Each and the variable declared in the For Each subflow. - In the While component, after the Break component is executed, the
variable will be the variable output by the component previous to While and the variable declared in the While subflow.

Example
- Add a For Each component and set the list to be traversed.
- Use a Choice component and add a condition in Conditional branch.
- On the Conditional branch node, add a Break component to jump out of the traversal process when
BMW is traversed.
