class Sawmill::RecordProcessor::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 records to STDOUT only if they have a “user” attribute of “daniel”:

processor = Sawmill::RecordProcessor.build do
  If(FilterByAttributes('user' => 'daniel'), Format(STDOUT))
end

Create an “if” conditional.

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