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.
- 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.
