Fires an event for each item in the input list, and collects the results into a new list.
This node is useful for performing the same (or similar) sequence of steps on each item in a list. For example, you could use this node to take a list of images and apply an effect to each one. This is simpler and more flexible than copying and pasting the same sequence of nodes multiple times into your composition — you can easily change the number of iterations and the sequence of steps performed for each iteration.
Start Processing — When it receives an event, clears the node’s internal list and causes the first in a series of events to fire from
Item — Sequentially fires an event for each item in the
Start Processing input list. Use this output to execute a chain of nodes many times.
Processed Item — This port needs to receive each event fired by the
Item port. When it receives an event, it appends its data to the node’s internal list, and it causes either
Finished Processing to fire (depending on whether there are more list items to process).
Finished Processing — Fires an event containing the final list when iteration is complete.
Start Processing port’s value is an empty list when it receives an event, no events are fired from
Finished Processing immediately fires an event with an empty list.
Start Processing port receives an event while the node is still iterating through the list for the previous
Start Processing event, then the later
Start Processing event is ignored (dropped). To avoid having events ignored, you can modify your composition to limit the rate at which events hit this node.
