I develop in Java. Thinking of switching to Kotlin (rather than Scala). Here is how the relevant code looks in my NifiRestClient, which uses Swagger generated REST client to access NiFi REST API.
/* * List all NiFi processors in this release */ public List<String> listAllProcessors() { List<String> processors = new ArrayList<>(); try { flowApi.getProcessorTypes() .getProcessorTypes() .forEach(dto -> { // get processor short type from class name String type = dto.getType(); type = type.substring(type.lastIndexOf('.') + 1); processors.add(type); } ); } catch (Exception ae) { printApiException("NifiRestClient#listAllProcessors", ae); throw new IllegalArgumentException("Failed to obtain a list of all available NiFi processors"); } processors.sort(Comparator.naturalOrder()); return processors; } } From: Daniel Chaffelson <chaffel...@gmail.com> Sent: Tuesday, November 13, 2018 7:57 AM To: users@nifi.apache.org Subject: Re: Easiest way to list all NiFi processors in a release. There is also a shortcut function NiPyApi for this, as it is handy when procedurally deploying flows: https://nipyapi.readthedocs.io/en/latest/_modules/nipyapi/canvas.html#list_all_processor_types On Mon, Nov 12, 2018 at 6:23 PM Pierre Villard <pierre.villard...@gmail.com<mailto:pierre.villard...@gmail.com>> wrote: Hi Vitaly, Yes there is one [1]: GET on /flow/processor-types Easiest way to find out is to use the developer tool of your browser.
