Class VMAssignmentResult

java.lang.Object

com.netflix.fenzo.VMAssignmentResult

public class VMAssignmentResult
extends java.lang.Object

Result of resource assignments for a host (VM). When you call your task scheduler's scheduleOnce() method to schedule a set of tasks, that method returns a SchedulingResult. That object includes the method getResultMap() which returns a map of host names to VMAssignmentResult objects. Those objects in turn have the getLeasesUsed() and getTasksAssigned() methods, which return information about the resource offers that participated in the assignments and which tasks were assigned on those hosts, in the form of VirtualMachineLease objects and TaskAssignmentResult objects respectively. This approach will give you insight into which tasks have been assigned to which hosts in the current scheduling round (but not about which tasks are already running on those hosts).
