Event::ExecFlow::Scheduler − Abstract class for parallel scheduling
#−− Create a new Scheduler object my $scheduler = Event::ExecFlow::Scheduler::XYZ−>new ( ... ); #−− Attach scheduler to a group job with parallel execution $group_job−>set_parallel(1); $group_job−>set_scheduler($scheduler); #−− The following methods gets called by Event::ExecFlow #−− at runtime $scheduler−>schedule_job($job); $scheduler−>job_finished($job);
This abstract base class represents just an interface which needs to be implemented by custom schedulers for controlling the execution of jobs in a Event::ExecFlow::Group which has the parallel option set.
Event::ExecFlow ships a very simple example for a scheduler which just limits the maximum number of parallel executed jobs: Event::ExecFlow::Scheduler::SimpleMax.
