Iterator is a special type of module allowing to split arrays into single bundles.

Example: Save email attachments to Dropbox

The below scenario shows how to retrieve emails with attachments and save the attachments as single files to a selected Dropbox folder.

Every email can contain an array of attachments. The Email module (iterator) Retrieve attachments inserted after the first module will enable to handle each attachment separately. The iterator will split each received array of attachments into single bundles which will then be saved one at a time to selected Dropbox folder.

Setting up an iterator

Setting an iterator is done in the same way as setting a module. The source module that inputs bundles to the iterator is to be specified first.
