6 SVK::Log::FilterPipeline - a pipeline of log filter objects
7
9 An SVK::Log::FilterPipeline represents a particular collection of log
10 filter objects each of which needs to be called in turn.
11
13 new
14 Construct a new SVK::Log::FilterPipeline object by constructing the
15 specific filters that will handle the details and preparing for the
16 first revision.
17
18 build_filter_object
19 Given the name of a filter, try and construct an appropriate filter
20 object. Search @INC for modules that match the name given. If no
21 appropriate classes are available, we die with an appropriate warning.
22
23 This method creates an object for the filter by calling its new()
24 method
25
26 filter
27 SVK::Command::Log calls this routine when it wants to display (or
28 process) a revision. The method then dispatches the information to the
29 methods of the necessary filter objects in the pipeline to perform the
30 real work.
31
32 finished
33 Tell all the filters that their jobs are done by calling "footer" and
34 "teardown" on each one.
35
36 get_pipeline_command
37 Examine an exception to determine if it's a pipeline control exception.
38 If it is, return the desired pipeline command. If it's not, rethrow
39 the exception. If no exception is provided, the command 'continue' is
40 returned.
41
42 present_revision
43 Display a single revision by passing it to the pipeline's presentation
44 filter.
45
46 run_pipeline
47 Send a revision down the pipeline. Provide revision information to the
48 revision() method of each filter in the pipeline until one of them says
49 to stop. Then return the pipeline command.
50
51 set_up_presentation
52 Handle initial set up for the presentation filter. This should only be
53 called once during an SVK::Log::FilterPipeline's lifetime.
54
55 set_up_selection
56 Handle initial set up for the selection filter pipeline. This should
57 only be called once during "SVK::Log::FilterPipeline"'s lifetime.
58
59 split_filter
60 Split a string into a filter name and an arbitrary argument string.
61
62 split_selectors
63 Split the description of the selection filter pipeline into individual
64 filter names and their arguments. Each filter is separated by a '|'
65 character. Literal pipe characters are included with '\|'.
