  orca.tests.core.SimpleLoadSource

All Implemented Interfaces:

IInitialize, ILoadSource

public class SimpleLoadSource
extends java.lang.Object
implements ILoadSource

Very simple demand. Creates demand either once (if oneRequestOnly used) or on every cycle. Only bids for one resource type and the same number of resources and term length every time.

slice

protected CodSlice slice

The slice

sm

protected ServiceManager sm

The service manager

clock

The clock

logger

protected LoggingTool logger

The logger

CLOCK_SKEW

public static final long CLOCK_SKEW

The amount of time over specific policy decisions the SM must add when communicating with other actors (e.g. redeem() and renew()). Clock skew must be at least one if the SM is ticked after the agent and/or authority At some point in time we may want this to not be static and learn it from what we see in the system, but for now it is static.
