Decides whether to keep an item by comparing a value from the item against a value produced by a transformer. This is useful when the value you want to compare against is not fixed text but something you have to build or look up first, such as the set of allowed codes produced by a transformer. The transformer produces a reference result, then a value from the item is compared against a value from that result, and the item is kept only when the comparison succeeds.

Sample data

This filter answers yes or no for each item, so there is no before and after. The example runs a transformer that produces { "allowed": "paid" }, then compares each item’s status against that allowed value with “equals”, so only paid items are kept.
