18 /** @brief Simulation Agent
20 * An actor may be defined as a code executing in a location (host).
22 * All actors should be started from the XML deployment file (using the @link{s4u::Engine::loadDeployment()}),
23 * even if you can also start new actors directly.
24 * Separating the deployment in the XML from the logic in the code is a good habit as it makes your simulation easier
25 * to adapt to new settings.
27 * The code that you define for a given actor should be placed in the main method that is virtual.
28 * For example, a Worker actor should be declared as follows:
31 * #include "s4u/actor.hpp"
33 * class Worker : simgrid::s4u::Actor {
35 * int main(int argc, char **argv) {
36 * printf("Hello s4u");
45 Actor(const char*name, s4u::Host *host, int argc, char **argv);
46 Actor(const char*name, s4u::Host *host, int argc, char **argv, double killTime);
49 /** The main method of your agent */
50 virtual int main(int argc, char **argv)=0;
52 /** The Actor that is currently running */
53 static Actor *current();
54 /** Retrieves the actor that have the given PID (or NULL if not existing) */
55 static Actor *byPid(int pid);
57 /** Retrieves the name of that actor */
59 /** Retrieves the host on which that actor is running */
61 /** Retrieves the PID of that actor */
64 /** If set to true, the actor will automatically restart when its host reboots */
65 void setAutoRestart(bool autorestart);
66 /** Sets the time at which that actor should be killed */
67 void setKillTime(double time);
68 /** Retrieves the time at which that actor will be killed (or -1 if not set) */
71 /** Ask kindly to all actors to die. Only the issuer will survive. */
72 static void killAll();
73 /** Ask the actor to die.
75 * It will only notice your request when doing a simcall next time (a communication or similar).
76 * SimGrid sometimes have issues when you kill actors that are currently communicating and such. We are working on it to fix the issues.
