Pipeline::Segment - basic class for a segment
use Pipeline::Segment; my $ps = Pipeline::Segment->new(); $ps->dispatch();
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.
The Pipeline::Segment
class inherits from Pipeline::Base
and therefore also has any additional methods that its superclass may have.
The init
method is called at construction time. Any arguments passed to the new
method are passed to it.
The dispatch
method causes the segment to perform its action.
The dispatch_method
gets and sets the method that gets called on dispatch, by default this is the dispatch()
method.
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.
The store
method gets the current store.
The parent
method returns the pipeline that the segment is current operating from. It is set at dispatch time by the calling pipeline.
