Instance Method Details

#Delta(array, net: world.net( :Top )) ⇒ Object

Expects an array of transitions, and :net named argument. Returns a single delta feature belonging to the net for this place, and those upstream T transitions, that are also in the included in the array. If no ordered arguments are given, complete set of upstream T transitions is assumed. If no :net is given, Top is assumed.

  net.State.Feature.Delta( self, transitions: transitions )
end

#delta(*transitions, net: world.net( :Top )) ⇒ Object

Expects an arbitrary number of transitions, and :net named argument. Returns a single delta feature belonging to the net for this place, and those upstream T transitions, that are also in the included among the arguments. If no ordered arguments are given, complete set of upstream T transitions is assumed. If no :net is given, Top is assumed.

end

#Deltas(array, net: world.net( :Top )) ⇒ Object

Expects an array of transitions, and :net named argument. Returns a feature set belonging to the net, consisting of the features for this place, and those upstream T transitions, that are also included in the array. If no :net is given, Top is assumed.

#deltas(*transitions, net: world.net( :Top )) ⇒ Object

Expects an arbitrary number of transitions, and :net named argument. Returns a feature set belonging to the net, constisting of the features for this place, and those upstream T transitions, that are also included in the array. If no ordered arguments are given, complete set of upstream T transitions is assumed. If no :net is given, Top is assumed.

Expects an arbitrary number of transitions, and :net named argument. Returns a single gradient feature belonging to the net for this place, and those upstream T transitions, that are also in the included among the arguments. If no ordered arguments are given, complete set of upstream T transitions is assumed. If no :net is given, Top is assumed.
