module ActiveJob #:nodoc:
  # = Active Job
  #
  # Active Job objects can be configured to work with different backend
  # queuing frameworks. To specify a queue adapter to use:
  #
  #   ActiveJob::Base.queue_adapter = :inline
  #
  # A list of supported adapters can be found in QueueAdapters.
  #
  # Active Job objects can be defined by creating a class that inherits
  # from the ActiveJob::Base class. The only necessary method to
  # implement is the "perform" method.
  #
  # To define an Active Job object:
  #
  #   class ProcessPhotoJob < ActiveJob::Base
  #     def perform(photo)
  #       photo.watermark!('Rails')
  #       photo.rotate!(90.degrees)
  #       photo.resize_to_fit!(300, 300)
  #       photo.upload!
  #     end
  #   end
  #
  # Records that are passed in are serialized/deserialized using Global
  # ID. More information can be found in Arguments.
  #
  # To enqueue a job to be performed as soon as the queueing system is free:
  #
  #   ProcessPhotoJob.perform_later(photo)
  #
  # To enqueue a job to be processed at some point in the future:
  #
  #   ProcessPhotoJob.set(wait_until: Date.tomorrow.noon).perform_later(photo)
  #
  # More information can be found in ActiveJob::Core::ClassMethods#set
  #
  # A job can also be processed immediately without sending to the queue:
  #
  #  ProcessPhotoJob.perform_now(photo)
  #
  # == Exceptions
  #
  # * DeserializationError - Error class for deserialization errors.
  # * SerializationError - Error class for serialization errors.
