# HG changeset patch # User Kaitlin Rupert <karupert(a)us.ibm.com&gt; # Date 1194471308 28800 # Node ID 5959f8f0e5e87540fb7da0bc5a0365388112452b # Parent 404c4803b1b542676c4d283226a7cc3b7f3ab58d Add association results filtering. This adds result filtering so that an association only returns instances that match the result class specified during the query. Such an example is the following: HostedService needs to return VSMS and RPCS instances when queried using CIM_ManagedElement as the result class. However, if CIM_VSMS is specified as the result class, then only the VSMS instance needs to be returned.
