NAME

Pipeline::Segment - basic class for a segment

SYNOPSIS

use Pipeline::Segment;
my $ps = Pipeline::Segment->new();
$ps->dispatch();

DESCRIPTION

Pipeline::Segment is designed as a part of the Pipeline system. The Pipeline::Segment class is designed to be subclassed as a part of the Pipeline system. The primary method that needs to be overloaded is the dispatch method, which the Pipeline class uses to enter each individual segment that it contains.

METHODS

The Pipeline::Segment class inherits from Pipeline::Base and therefore also has any additional methods that its superclass may have.

init()

The init method is called at construction time. Any arguments passed to the new method are passed to it.

dispatch()

The dispatch method causes the segment to perform its action.

dispatch_method()

The dispatch_method gets and sets the method that gets called on dispatch, by default this is the dispatch() method.

cleanup_dispatch()

The cleanup_dispatch method does post-processing on the segment to ensure no nasty circular references are lying around, as well as disconnecting various objects that are only useful during a dispatch.

store()

The store method gets the current store.

parent()

The parent method returns the pipeline that the segment is current operating from. It is set at dispatch time by the calling pipeline.
