6 Pipeline::Segment - basic class for a segment

9 use Pipeline::Segment;
10 my $ps = Pipeline::Segment->new();
11 $ps->dispatch();
12
14 "Pipeline::Segment" is designed as a part of the "Pipeline" system.
15 The "Pipeline::Segment" class is designed to be subclassed as a part of
16 the Pipeline system. The primary method that needs to be overloaded is
17 the "dispatch" method, which the Pipeline class uses to enter each
18 individual segment that it contains.
19
21 The "Pipeline::Segment" class inherits from "Pipeline::Base" and there‐
22 fore also has any additional methods that its superclass may have.
23
24 init()
25 The "init" method is called at construction time. Any arguments
26 passed to the "new" method are passed to it.
27
28 dispatch()
29 The "dispatch" method causes the segment to perform its action.
30
31 dispatch_method()
32 The "dispatch_method" gets and sets the method that gets called on
33 dispatch, by default this is the "dispatch()" method.
34
35 cleanup_dispatch()
36 The "cleanup_dispatch" method does post-processing on the segment
37 to ensure no nasty circular references are lying around, as well as
38 disconnecting various objects that are only useful during a dis‐
39 patch.
40
41 store()
42 The "store" method gets the current store.
43
44 parent()
45 The "parent" method returns the pipeline that the segment is cur‐
46 rent operating from. It is set at dispatch time by the calling
47 pipeline.
