[Hawkular-dev] inventory API: can I get a feed ID from a resource ID?

[Lukas Krejci]

In Inventory 0.2.0.Alpha1 which I am about to release today if no breakage was 
discovered during my absence:

If you have the resource java object, which I think you have in agent, you 
simply do:

resourceObject.getPath().ids().getFeedId();

Long version:

All inventory entities now store a "canonical path" which is a path going down 
from tenant do the entity in question following the "contains" relationships.

The above call will take the resource object's path analyze it using the 
"ids()" call and will return the feed id, if the resource is contained within 
a feed or null, if the resource lives directly under an environment.

Also if you just store the resource ID, remember that that is only "locally 
unique" within your feed, so to reliably get the correct resource, you only 
can search for it within the feed:

inventory.tenants().getAll("asdf").environments().get("asf").feeds("myfeed")
.resources().get("resource-id");

If you also store the canonical path of the resource, you could do:

inventory.inspect(CanonicalPath.fromString("resource-path"), 
Resources.Single.class);

which would return to you the same access object as the above call.

So when you create your resource, you supply locally unique id, and can use 
the access object returned from the create method to get the newly created 
resource which will contain its full canonical path and all the other details.
