René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Add a flag to include/exclude inputs from preview calls","articleBody":"Let's add `boolean isPreviewed()` to `ModuleItem`, and `boolean preview() default true;` to `Parameter`, which control whether each individual parameter calls the `preview()` method after it changes.\n\nNote that in cases where parameter `foo` triggers a callback which changes `bar`, but `foo` declares `preview=false`, this will _not_ trigger a preview even though `bar` also changed, because callbacks and previews do not chain. It is the responsibility of the programmer to keep track of such \"parameter dependencies\" and structure things as needed for their use case.\n\nThanks to Adrian Daerr for [the suggestion](http://imagej.net/pipermail/imagej-devel/2015-August/002685.html).\n","author":{"url":"https://github.com/ctrueden","@type":"Person","name":"ctrueden"},"datePublished":"2015-08-27T18:52:36.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/184/scijava-common/issues/184"}
