Interface Summary

Interface	Description
AutoScaleAction	Describes an autoscaling action, either the scaling up or down of an autoscaling group.
AutoScaleRule	A rule that defines when to scale the number of hosts of a certain type.
ConstraintEvaluator	A constraint evaluator inspects a target to decide whether or not its attributes are satisfactory according to some standard given the current state of task assignments in the system at large.
TaskIterator
TaskRequest	Describes a task to be assigned to a host and its requirements.
TaskTrackerState	The state of the tasks that are tracked by the task scheduler.
VirtualMachineCurrentState	Represents the current state of the host (virtual machine) that Fenzo is considering for a task assignment.
VirtualMachineLease	A representation of a lease (resource offer).
VMTaskFitnessCalculator	Interface representing a task fitness calculator, or scheduling optimization plugin.

Class Summary

Class	Description
AssignmentFailure	An assignment failure to indicate that a particular task could not be scheduled because a quantifiable resource was insufficient, along with the amount of the resource that was requested (asked) by the task, the amount already used, and the amount available on the target.
AsSoftConstraint	Converts a hard constraint into a soft constraint.
ConstraintEvaluator.Result	The result of the evaluation of a ConstraintEvaluator.
ConstraintFailure	An object that encapsulates the case of a target failing to satisfy a constraint mandated by a task and implemented by a ConstraintEvaluator.
DefaultFitnessCalculator	A default fitness calculator that always finds any target to be perfectly fit for any task.
PreferentialNamedConsumableResourceSet	This encapsulates preferential resource sets available on a VM.
PreferentialNamedConsumableResourceSet.ConsumeResult
PreferentialNamedConsumableResourceSet.PreferentialNamedConsumableResource
ScaleDownAction	An autoscale action that indicates an autoscale group is to be scaled down.
ScaleUpAction	An autoscale action indicating that the autoscale group is to be scaled up.
SchedulingResult	The result of a scheduling trial, as returned by scheduleOnce().
TaskAssignmentResult	Encapsulates the results of attempting to assign a task to a host.
TaskRequest.AssignedResources
TaskRequest.NamedResourceSetRequest
TaskScheduler	A scheduling service that you can use to optimize the assignment of tasks to hosts within a Mesos framework.
TaskScheduler.Builder	The Builder is how you construct a TaskScheduler object with particular characteristics.
TaskSchedulingService	A task scheduling service that maintains a scheduling loop to continuously assign resources to tasks pending in the queue.
TaskSchedulingService.Builder
TaskTracker	Class to keep track of task assignments.
TaskTracker.ActiveTask	An active task in the scheduler.
VirtualMachineLease.Range	Describes a [beginning, end] range.
VMAssignmentResult	Result of resource assignments for a host (VM).

Enum Summary

Enum	Description
AutoScaleAction.Type	Indicates whether the autoscale action is to scale up or to scale down.
VMResource	Enumeration of resources avaialble on hosts (VMs)
