NAME
       SVK::Log::FilterPipeline - a pipeline of log filter objects

DESCRIPTION
       An SVK::Log::FilterPipeline represents a particular collection of log
       filter objects each of which needs to be called in turn.

MMEETTHHOODDSS
       nneeww

       Construct a new SVK::Log::FilterPipeline object by constructing the
       specific filters that will handle the details and preparing for the
       first revision.

       bbuuiillddffiilltteerroobbjjeecctt

       Given the name of a filter, try and construct an appropriate filter
       object.  Search @INC for modules that match the name given.  If no
       appropriate classes are available, we die with an appropriate warning.

       This method creates an object for the filter by calling its new()
       method

       ffiilltteerr

       SVK::Command::Log calls this routine when it wants to display (or
       process) a revision.  The method then dispatches the information to the
       methods of the necessary filter objects in the pipeline to perform the
       real work.

       ffiinniisshheedd

       Tell all the filters that their jobs are done by calling "footer" and
       "teardown" on each one.

       ggeettppiippeelliinneeccoommmmaanndd

       Examine an exception to determine if it's a pipeline control exception.
       If it is, return the desired pipeline command.  If it's not, rethrow
       the exception.  If no exception is provided, the command 'continue' is
       returned.

       pprreesseennttrreevviissiioonn

       Display a single revision by passing it to the pipeline's presentation
       filter.

       rruunnppiippeelliinnee

       Send a revision down the pipeline.  Provide revision information to the
       revision() method of each filter in the pipeline until one of them says
       to stop.  Then return the pipeline command.

       sseettuupppprreesseennttaattiioonn

       Handle initial set up for the presentation filter.  This should only be
       called once during an SVK::Log::FilterPipeline's lifetime.

       sseettuuppsseelleeccttiioonn

       Handle initial set up for the selection filter pipeline.  This should
       only be called once during "SVK::Log::FilterPipeline"'s lifetime.

       sspplliittffiilltteerr

       Split a string into a filter name and an arbitrary argument string.

       sspplliittsseelleeccttoorrss

       Split the description of the selection filter pipeline into individual
       filter names and their arguments.  Each filter is separated by a '|'
       character.  Literal pipe characters are included with '\|'.
