ptolemy.actor.Manager.iterate()
Invoke one iteration of the model. An iteration consists of first performing changes queued with requestChange() and type resolution, if necessary, and then invoking prefire(), fire(), and postfire(), in that order. If prefire() returns false, then fire() and postfire() are not invoked, and true is returned. Otherwise, fire() will be called once, followed by postfire(). The return value of postfire() is returned. Note that this method ignores finish and pause requests and thus determines a minimum granularity of the execution. Set the state of the manager to ITERATING. This method is read synchronized on the workspace.
@return True if postfire() returns true.
@exception KernelException If the model throws it, or if thereis no container.
