NAME

       Event::ExecFlow::Scheduler - Abstract class for parallel scheduling

SYNOPSIS

         #-- 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);

DESCRIPTION

       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.
