...41    # The API limits its length to no more then 50 charactors.  If the class itself is the42    # target, this value will either not be set or set to nil.  The reader should MUST return43    # nil in this case.44    #45    # finder_args [Array]: A possibly complex array of valuse that will be paseed to the46    # finder method in order to retrieve the target instance.  The API spesifies that the47    # array and all subelements must impliment the #to_yaml and #to_json method in48    # addation to being Marshalable. If the class itself is the49    # target, this value will either not be set or set to nil.  The reader should MUST return50    # nil in this case.51    #52    # method [String]:  The method to be sent to the target instance.  The API limits this value53    # to 50 charictars.  It MAY NOT be nil or empty.54    #55    # method_args [Array]: A possibly complex array of values to pass to the spesified method of56    # the target instance.  It must be marshalable.  The ORM layer is responcible to Marshal.dump57    # and Marshal.load these values.58    #59    # name [String]: If the ORM impliments the +for+ method, then it MUST store a name which the60    # API spesifies SHOULD be unique per target.  The ORM SHOULD NOT enforce this restriction, but61    # MAY assume it.   ORM's that do not impliment +for+ must none the less have a #name= method62    # that returns the value passed to it (as is normal with setter methods) and must not raise an error63    # when a hash of values includes name.  It must also respond to the name method with nil.  When64    # inplimented, name may be no longer then 255 characters.65    #66    # persistant [Boolean]: if this value is set to true a worker will not call destroy after running the job.67    # If it is nil or not set it may be assumed to be false,  and ORM may return nil instead of false in this68    # case.69    #70    # == Chained Jobs71    #72    # Chained Jobs are run after a job and allow for various function to take place such as logging and73    # error handleing.  There are three(3) categories for chaining :failure, :success, and :ensure.  The74    # ORM must impliment a getter and setter for each as described below.  This version does not75    # inpliment it, but ORMs should be be designed in such a way that :prior and :instead chains can be76    # added in future version of this API.77    # 78    # === Getters: 79    # getters should return an array of structures (Struct or equivelent)  representing the chained jobs80    # for this job.  The structure should have three(3) members and MAY be read-only.81    #82    # caller: An instance of the ORM class for the job in question (i.e. self)83    #84    # target: An instance of the ORM class for the chained job85    #86    # params: a Hash or other object that will be substituted for the special value '__params__' when calling87    # the target job.88    #89    # The object returned may have other methods and functionality.  Clients SHOULD NOT antisipate or use90    # these methods.91    # 92    # === Setters:93    # setters must accept five(5) differnt types of input.  Except as described below setters are NOT distructive,94    # that is job.failure=logme adds logme to the list of failure jobs and does not remove jobs that may have previously95    # been chained.  Clients should call save after using the setter to write the changes to disk96    #97    # ORM or Updater::Update:  Add this job to the chain, with no parameters. Updater::Update#orm will give the job.98    #99    # Array<ORM or Updater::Update>: Add each job in the array to the chain100    #101    # Hash(<ORM or Updater::Update>, params): Add the keys to the chain with the valuse as params.  Clients102    # should note that it is not possible to add multiple calls to the same job using this method.103    #104    # nil:  remove all jobs from this chain.  Clients Note, that this is the only way to remove a previously added105    # job from a chain.106    class Base107      108      # Every ORM should set this constant to a symbol that matches the most109      # obvious method used to retrive a known instance.  :get or :find are likely110      # candidates. 111      FINDER= nil112      113      # every ORM should set this to a method when called on an object producted by114      # that ORM will give a value that can be passed to the FINDER method to retrieve115      # the object from the datastore.  :id, _id, or :key are likely candidates116      ID = nil117      118      # Workers will call this method on a job before running it to insure that in the case119      # of multiple workers hiting the same queue only one will run the job.
