Where is the source code(github address and java class name) of /camunda/api/engine/engine/default/filter API?

After I started camunda-bpm-run-7.16.0 and login the camunda tasklist page and I can see all of the tasks pending on the current login user, I can see that the web page will invoke the below API:
http://127.0.0.1:8080/camunda/api/engine/engine/default/filter?firstResult=0&maxResults=2000&itemCount=false&resourceType=Task

where is the source code(github address and java class name) of /camunda/api/engine/engine/default/filter API? thank you.

Hi @henry007,

the implementation starts here: camunda-bpm-platform/FilterRestServiceImpl.java at master · camunda/camunda-bpm-platform · GitHub

Hope this helps, Ingo

Many thanks!
