DESCRIPTION
An SVK::Log::FilterPipeline represents a particular collection of log
filter objects each of which needs to be called in turn.
METHODS
new
Construct a new SVK::Log::FilterPipeline object by constructing the
specific filters that will handle the details and preparing for the
first revision.
build_filter_object
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
filter
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.
finished
Tell all the filters that their jobs are done by calling "footer" and
"teardown" on each one.
get_pipeline_command
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.
present_revision
Display a single revision by passing it to the pipeline's presentation
filter.
run_pipeline
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.
set_up_presentation
Handle initial set up for the presentation filter. This should only be
called once during an SVK::Log::FilterPipeline's lifetime.
set_up_selection
Handle initial set up for the selection filter pipeline. This should
only be called once during "SVK::Log::FilterPipeline"'s lifetime.
split_filter
Split a string into a filter name and an arbitrary argument string.
split_selectors
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 '\|'.
