Process Description

Objects that represent generic computational processes There are a great number of situations in which you may want to model a computational process as an object.An implementation of this sort of object generally looks like the following when somebody uses it. my $object = MyProcessThingy->new( ... ); my $rv = $object->run; if ( $rv ) { print "Thingy ran ok"; } else { print "Failed to run thingy"; }The Process family of modules are intended to be used as base and role classes for these types of objects. They are used to help identify process objects, and enforce a common API on these objects.The primary intent of this module is to provide a common base for objects that will be able to be used with various distributed processing systems, without itself actually implementing any form of distributed system.The scope of uses for Process includes solutions to address the following scenarios.A single CPU on a single hostMultiple CPUs on a single hostMultiple hosts on a single networkHosts distributed across the internetAny processing resource accessible via any mechanismTo put it another way, this family of classes is intended to addresses the separation of concerns between the processing of something, and the results of something.The actual ways in which the processes are run, and the handling of the results of the process are outside the scope of these classes.The Process class itself is the root of all of these classes. In fact, it is so abstract that it contains no functionality at all, and serves primarily to indicate that an object obeys the general rules of a Process class.Most of the basic Process modules are similar. They define how your object should behave (an API for a particular concept) without dictating a particular implementation.However, by using them, you are confirming to some processing system that your objects will obey particular rules, and thus can interact sanely with any processing system that follows the API.SYNOPSIS # Create the process my $object = MyProcess->new( ... ) or die("Invalid configuration format"); # Initialize it $object->prepare or die("Configuration not supportable"); # Execute the process $object->run or die("Error while trying to execute the process"); Requirements: · Perl
