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;
}
}

There is also a shortcut function NiPyApi for this, as it is handy when
procedurally deploying flows:

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. Anything
viewable/doable in the NiFi UI is a doable through REST API endpoints.

Is there a REST API to list all NiFi processors in a current NiFi release?
Thanks.
