definition execution

Third iteration: state is stored in agents, minimal deps.

abbreviations

cont ... container
defis ... definitions
ndx ... container number
idx ... sequential step
jdx ... parallel step
exch ... exchange interface

mem

mpd

  ;; generate a fresh mpd
  (def m (-> {}
          mpd/standard->
          mpd/name->
          mpd/descr->
          mpd/exch->
          mpd/cont->
          mpd/defi->))

mlooks like this:

{:Mp
 {:Standard "NN",
  :Name "generic",
  :Description "Default description",
  :Exchange {:Default {:Bool true}},
  :Container
  [{:Title "Default title",
    :Description "Default container description",
    :Element [:Default],
    :Definition [[{:TaskName "Common-wait"}]]}],
  :Definitions
  [{:DefinitionClass "default",
    :ShortDescr "Default description",
    :Condition
    [{:ExchangePath "Default.Bool", :Methode "eq", :Value true}],
    :Definition [[{:TaskName "Common-wait"}]]}]},
 :_id "mpd-nn-generic"}

(def mem (atom {}))
(up m)
(deref mem)

mem looks loke this:

{:mpd-nn-generic
 {:Standard "NN",
  :Name "generic",
  :Description "Default description",
  :Exchange #<Agent@4c66db73: nil>,
  :Container
  [{:Title "Default title",
    :Description "Default container description",
    :Element [:Default],
    :Definition [[{:TaskName "Common-wait"}]],
    :State
    #<Agent@4937c4d3: 
      {:states
       [{:mp-id :mpd-nn-generic,
         :struct :Container,
         :ndx 0,
         :idx 0,
         :jdx 0,
         :state :ready}],
       :ctrl :ready}>,
    :Future #<Future@9669e3c: :pending>}],
  :Definitions
  [{:DefinitionClass "default",
    :ShortDescr "Default description",
    :Condition
    [{:ExchangePath "Default.Bool", :Methode "eq", :Value true}],
    :Definition [[{:TaskName "Common-wait"}]],
    :State
    #<Agent@91f1b42: 
      {:states
       [{:mp-id :mpd-nn-generic,
         :struct :Definitions,
         :ndx 0,
