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
15 Construct a new SVK::Log::FilterPipeline object by constructing the
16 specific filters that will handle the details and preparing for the
17 first revision.
18
19 build_filter_object
20
21 Given the name of a filter, try and construct an appropriate filter
22 object. Search @INC for modules that match the name given. If no
23 appropriate classes are available, we die with an appropriate warning.
24
25 This method creates an object for the filter by calling its new()
26 method
27
28 filter
29
30 SVK::Command::Log calls this routine when it wants to display (or
31 process) a revision. The method then dispatches the information to the
32 methods of the necessary filter objects in the pipeline to perform the
33 real work.
34
35 finished
36
37 Tell all the filters that their jobs are done by calling "footer" and
38 "teardown" on each one.
39
40 get_pipeline_command
41
42 Examine an exception to determine if it's a pipeline control exception.
43 If it is, return the desired pipeline command. If it's not, rethrow
44 the exception. If no exception is provided, the command 'continue' is
45 returned.
46
47 present_revision
48
49 Display a single revision by passing it to the pipeline's presentation
50 filter.
51
52 run_pipeline
53
54 Send a revision down the pipeline. Provide revision information to the
55 revision() method of each filter in the pipeline until one of them says
56 to stop. Then return the pipeline command.
57
58 set_up_presentation
59
60 Handle initial set up for the presentation filter. This should only be
61 called once during an SVK::Log::FilterPipeline's lifetime.
62
63 set_up_selection
64
65 Handle initial set up for the selection filter pipeline. This should
66 only be called once during "SVK::Log::FilterPipeline"'s lifetime.
67
68 split_filter
69
70 Split a string into a filter name and an arbitrary argument string.
71
72 split_selectors
73
74 Split the description of the selection filter pipeline into individual
75 filter names and their arguments. Each filter is separated by a '⎪'
76 character. Literal pipe characters are included with '\⎪'.
