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.
