Defined in:
lib/rubocop/cop/legion/extension/absorber_missing_pattern.rb

Overview

Detects absorber classes inside an ‘Absorbers` namespace that do not call the `pattern` DSL method. Without `pattern`, the absorber will not match any events and will be silently inactive.

Examples:

# bad
module Absorbers
  class Foo
    def absorb(event)
      process(event)
    end
  end
end

# good
module Absorbers
  class Foo
    pattern 'some.event.*'

    def absorb(event)
      process(event)
    end
  end
end
