Defined in:

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
