What’s the output from for-each scope in MuleSoft?

The output from a For Each scope in MuleSoft depends on the processors that you place inside the scope. The For Each scope will process each element of the collection one at a time, and the output from the processors will be accumulated into a list. The list will then be set as the payload of the message that is returned from the For Each scope.

For example, if you have a For Each scope that contains a Log processor, the output will be a log message for each element of the collection. If you have a For Each scope that contains a Transform Message processor, the output will be a transformed version of each element of the collection.

The specific output from a For Each scope will also depend on the type of collection that is being processed. If you are processing a list of strings, the output will be a list of strings. If you are processing a list of objects, the output will be a list of objects.

Here is an example of a For Each scope that contains a Log processor:

 

XML

<foreach collection="input">
  <logger level="INFO"/>
</foreach>

This code will output a log message for each element of the input collection. The output will look something like this:

 

[INFO] Processing element 1
[INFO] Processing element 2
[INFO] Processing element 3

Here is an example of a For Each scope that contains a Transform Message processor:

 

XML

<foreach collection="input">
  <transform message="${element}" into="java:my.custom.Transformer"/>
</foreach>

This code will transform each element of the input collection using the my.custom.Transformer class. The output will depend on the implementation of the my.custom.Transformer class.

In general, the output from a For Each scope will be a list of the outputs from the processors that are contained in the scope. The specific output will depend on the type of collection that is being processed and the type of processors that are used.
