w is a UUID string,

l is a list of strings, the first of which corresponds to the UML type, and all remaining ones (if any) correspond to stereotypes, and

e is a named table in JSON format, as described on the QueryModel page.

The GetInstances(t) calling sequence downloads and caches all instance specifications whose classifier is t (and whose UUIDs are contained in t["_instanceSpecificationOfClassifier"]) in bulk. Typically, t is a Block.

The GetSlots(t) calling sequence downloads and caches all slots whose defining feature is t (and whose UUIDs are contained in t["_slotOfDefiningFeature"]) in bulk. Typically, t is a Property.

All calling sequences return the empty list $\left[\right]$ if no such instance specifications or slots exist.

The GetInstances(u) and GetSlots(u) calling sequences first download the SysML model element specified by the UUID in u, and then proceed as above. If a model element with the given UUID cannot be found on the server, an error is raised.

The GetInstances(q) and GetSlots(q) calling sequences first look up, download and cache the SysML model element specified by the qualified name q (see QueryModel), and then proceed as above. If a model element with the given qualified name cannot be found on the server, an error is raised.

If the first argument is a table in JSON format without an "@id" field, then it is assumed to be a valid model element, corresponding to the t calling sequence. If the first argument is a string that is not a syntactically valid UUID, then it is assumed to be a qualified name, corresponding to the q calling sequence.

Both GetChildren and GetSlots can return slots. The difference is that GetSlots returns all slots with the same defining feature, which will usually belong to different instances, while GetChildren returns all slots belonging to the same instance, which will usually have different defining features.

Model elements that have already been downloaded and cached previously are retrieved from the cache instead of re-downloaded from the server.

Use of this command requires an active server connection, using the Connect command.  If such a connection does not exist, an error will be raised.
