Interface Workload

All Superinterfaces:

java.lang.Comparable<Workload>

All Known Implementing Classes:

WorkloadWM1, WorkloadWM2

public interface Workload
extends java.lang.Comparable<Workload>

This interface is used to represent the workload associated with a task, the interface is used by the implementation for the two workload models being supported by the broker. It extends the Comparable interface, since the workloads need to be able to be sorted in an earliest deadline first order.
