Thanks, looks like it passed the second time :)

This would return all the interfaces in the sandbox, also the one connecting to other endpoints.
Since this function belongs to Endpoint API, I'd expect it to return only the interface owned by this Endpoint.

If the goal instead is to get all the interfaces on the sandbox, I think we should wait for #365 to be merged and add the new API to the Sandbox interface.

@boucher Now that #365 is merged, are you planning to modify this PR to add the new method to the Sandbox interface instead of the Endpoint interface ?

[boucher]

Sure, let me take a look at what that involves.

[aboch]

Thanks !

@aboch yes, the goal is to get all the interfaces of the containers.
@boucher I can update the PR to move the function to sandbox interface based on #365 if you do not mind.

[boucher]

@huikang That would be great.

Closing as #518 is a rework of this PR.
