def Im array
  places( array ).map { |place|
    place.free? ? initial_marking( place ) : marking_clamp( place )
  }
end

#im(*places) ⇒ Object

Expects an arbitrary number of places or place identifiers, and returns their marking as it would appear right after the simulation reset. If no arguments are given, returns all of them.

def im *places
  return Im places() if places.empty?
  Im( places )
end

#im_vector(ids = nil) ⇒ Object

Returns initial marking vector for all places. Like #initial_marking, but returns a column vector.

  im( ids ).to_column_vector
end

#initial_marking(arg = L! ) ⇒ Object

Expects a single free place and returns the value of its initial marking.

def initial_marking arg=L!
  return initial_markings( arg ).first unless arg.local_object?
  @initial_marking or fail TypeError, "+@initial_marking+ not present yet!"
end

#initial_marking_vector(ids = nil) ⇒ Object

Returns initial marking vector for free places. Like #initial_marking, but returns a column vector.

def initial_marking_vector ids=nil
  initial_marking( ids ).to_column_vector
end

#initial_markings(*free_places) ⇒ Object

Expects an arbitrary number of arguments identifying free places, whose initial markings are then returned. If no arguments are given, acts as a getter of @initial_marking instance variable.

def initial_markings *free_places
  return initial_marking if free_places.empty?
  Initial_markings( free_places )
end

#Initial_markings(array) ⇒ Object Also known as: initial_Markings
