==============================
|

|
|
parentId is any distributed object id.
|
||
|
|
zoneId is a uint32, defaults to None (all zones). Try zone 2 if
|
||
|
|
you're not sure which zone to use (0 is a bad/null zone and
|
||
|
|
1 has had reserved use in the past as a no messages zone, while
|
||
|
|
2 has traditionally been a global, uber, misc stuff zone).
|
||
|
|
dclassType is a distributed class type filter, defaults
|
||
|
|
to None (no filter).
|
||
|
|
|
||
|
|
If dclassName is None then all objects in the zone are returned;
|
||
|
|
otherwise the list is filtered to only include objects of that type.
