The primary responsibility or an input component is to choose the transition to take, from the given possible transitions, calculated for the current state. If the chosen transition is a time transition, the input component must also decide the amount of time to delay.

Only one input mode, and thus one input component, can be used for each simulation. By default, the GUI input mode is used.
