class Sawmill::EntryProcessor::And

A boolean processor that returns true if and only if all its child processors return true. This version short-circuits the processing, so once one child returns false, subsequent children are not called at all.

For example, this builds a processor that sends formatted log entries to STDOUT only if their level is at least INFO AND the progname is is “rails”:

processor = Sawmill::EntryProcessor.build do
  If(And(FilterByBasicFields(:level => :INFO),
         FilterByBasicFields(:progname => 'rails')),
     Format(STDOUT))
end
