Class ResourceConstraints

java.lang.Object
  hu.mta.sztaki.lpds.cloud.simulator.iaas.ResourceConstraints

All Implemented Interfaces:

Comparable<ResourceConstraints>

public class ResourceConstraints
extends Object
implements Comparable<ResourceConstraints>

This class is intentionally non mutable, allowing those users (e.g. the class of IaaSService or Scheduler) who would want to share their current capacities not to create a new instance for every new query.
