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