class Sawmill::EntryProcessor::If

An “if” conditional.

Takes a boolean condition processor and executes a processor on true (and optionally another one on false).

For example, this builds a processor that sends formatted log entries to STDOUT only if their level is at least INFO:

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

Public Class Methods

Create an “if” conditional.

The first parameter must be a processor whose methods return a boolean value indicating whether the entry should be accepted. The second parameter is a processor to run on accepted entries. The optional third parameter is an “else” processor to run on rejected entries.
