Event::ExecFlow::Scheduler

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.
