Can't figure out how to get list of service client or servers names and types by node

[usmahm]

Is there a way to get list of service client or servers names and types by node, similar to how we can get list of publishers or subscribers names and node using these respective methods getPublisherNamesAndTypesByNode, getSubscriptionNamesAndTypesByNode ?

@usmahm thanks for your feedback, I think you are finding:

rclnodejs/lib/node.js

Line 977 in baba669

getServiceNamesAndTypesByNode(nodeName, namespace) {

Also check out the document.

For the client equivalent, after checking with the latest rcl which is the middleware library rclnodjs builds on, there dose kind of method to be exposed, see below:

https://github.com/ros2/rcl/blob/cc72fc1769ce9e6557c0f01efde982b3212e77b0/rcl/include/rcl/graph.h#L254

I'm going to add the missing method for getting client, thanks!

@minggangw, yes thank you.

I saw how to get the service names and types using getServiceNamesAndTypesByNode , however, I couldn't find the pair that gets the client names and types, and I need both for what I am trying to implement.

When do you think we can get the method for getting client?
Also, are there any other ways I can achieve that pending the time that is available?

The implementation of getClientNamesAndTypesByNode is missing, I will prepare a PR to add it back. Hopefully early this week.

#1097 merged, a new release of rclnodejs will be followed later. You can try with below in advance.
