#initial_marking(*args) ⇒ Object Also known as: im

Returns or modifies current initial marking(s) as indicated by the argument field:

  • No arguments: returns current imc

  • Exactly one ordered argument: it is assumed to identify a place whose im in the current imc will be returned.

  • A hash: Assumed to be { place_id => im }, current imc is updated with it.

  • One ordered argument, and a hash: The imc identified by the ordered ordered arg is updated with the hash.

  • 2 ordered arguments: First is assumed to identify an imc, second place whose im acc. to that imc to return.
