6 Event::ExecFlow::Scheduler - Abstract class for parallel scheduling
7
9 #-- Create a new Scheduler object
10 my $scheduler = Event::ExecFlow::Scheduler::XYZ->new ( ... );
11
12 #-- Attach scheduler to a group job with parallel execution
13 $group_job->set_parallel(1);
14 $group_job->set_scheduler($scheduler);
15
16 #-- The following methods gets called by Event::ExecFlow
17 #-- at runtime
18 $scheduler->schedule_job($job);
19 $scheduler->job_finished($job);

22 This abstract base class represents just an interface which needs to be
23 implemented by custom schedulers for controlling the execution of jobs
24 in a Event::ExecFlow::Group which has the parallel option set.
25
26 Event::ExecFlow ships a very simple example for a scheduler which just
27 limits the maximum number of parallel executed jobs:
28 Event::ExecFlow::Scheduler::SimpleMax.
