Package protocols.apps.canvas.timers

Class ControlTimer

java.lang.Object
pt.unl.fct.di.novasys.babel.generic.ProtoTimer
protocols.apps.canvas.timers.ControlTimer
All Implemented Interfaces:
Cloneable
public class ControlTimer extends pt.unl.fct.di.novasys.babel.generic.ProtoTimer
Polls the shared control file in orchestrator-coordinated workload mode (see CanvasApp.uponControlTimer). The experiment script lets the whole system join and settle, then writes RUN to begin the paint workload on every node at once, and later STOP to cease — so painting starts only once ALL nodes are present (a node's own view being stable is not enough; late joiners would miss its early ops). Set up with setupPeriodicTimer(...) when canvas.workload.controlFile is configured; otherwise the node uses the legacy single start-delay timer.

Stateless, so clone() returns this — the Babel convention.
