SVK::Log::Filter::Head - pass the first N revisions DESCRIPTION
The Head filter requires a single integer as its argument. The integer represents the number of revisions that the filter should allow to pass down the filter pipeline. Head only counts revisions that it sees, so if an upstream filter causes the pipeline to skip a revision, Head won't (and can't) count it. As soon as Head has seen the specified number of revisions, it stops the pipeline from processing any further revisions. This filter is particularly useful when searching log messages for patterns (see SVK::Log::Filter::Grep). For example, to view the first three revisions with messages that match "foo", one might use svk log --filter "grep foo | head 3" STASH
/PROPERTY MODIFICATIONS Head leaves all properties and the stash intact. perl v5.10.0 2008-08-04 SVK::Log::Filter::Head(3)

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. 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 '|'. perl v5.10.0 2008-08-04 SVK::Log::FilterPipeline(3)
