Constructor Summary

BusLEDOutput(int serial, Metadata metadata_I_want)

Method Summary

Event	alternateStep(Event prev_event, Event new_event, int step) Returns an event that represents the "alternate" or "opposite" of what is displayed by the other transition methods in order to create a "flashing" effect.
Event	changeblindTransStep(Event prev_event, Event new_event, int step_num) Returns an event that is somewhere between the start and end points of a change blind transition, depending on the display_step and the number of steps involved in the transition.
protected void	displayEvent(Event e) This code needs to actually display the event (e.g.
Event	endTransition(Event prev_event, Event new_event, int step) Returns an event representative of the end state of a transition.
void	initialize() Called when the interface kit with serial number SERVO is attached.
Event	interruptTransStep(Event prev_event, Event new_event, int step_num) Returns an event that is somewhere between the start and end points of a interrupt transition, depending on the display_step and the number of steps involved in the transition.
Event	makeawareTransStep(Event prev_event, Event new_event, int step_num) Returns an event that is somewhere between the start and end points of a make aware transition, depending on the display_step and the number of steps involved in the transition.
Event	startTransition(Event prev_event, Event new_event, int step) Returns an event representative of the beginning of a transition.

Constructor Detail

BusLEDOutput

public BusLEDOutput(int serial,
                    Metadata metadata_I_want)

Method Detail

initialize

public void initialize()

Called when the interface kit with serial number SERVO is attached.

Specified by:

initialize in class PhidgetInterfaceKitOutput

displayEvent

protected void displayEvent(Event e)

Description copied from class: Output

This code needs to actually display the event (e.g. print the text, show the image, etc). This function should return as fast as possible.

Specified by:

displayEvent in class Output

Parameters:

e - This event to be displayed

translateTime2Lights

protected int translateTime2Lights(double time)

startTransition

public Event startTransition(Event prev_event,
                             Event new_event,
                             int step)

Description copied from interface: Animatable

Returns an event representative of the beginning of a transition.

Specified by:

startTransition in interface Animatable

Parameters:

prev_event - the previous event sent to this Output (null if the new event is the first).

new_event - the new event to be displayed on the Output.

step - a number indicating the display order of the event returned if the Transition is creating a set of events.

Returns:

Event

endTransition

public Event endTransition(Event prev_event,
                           Event new_event,
                           int step)

Description copied from interface: Animatable

Returns an event representative of the end state of a transition. This typically involves the new event data.

Specified by:

endTransition in interface Animatable

Parameters:

prev_event - the previous event sent to this Output (null if the new event is the first).

new_event - the new event to be displayed on the Output.

step - a number indicating the display order of the event returned if the Transition is creating a set of events.

Returns:

Event

changeblindTransStep

public Event changeblindTransStep(Event prev_event,
                                  Event new_event,
                                  int step_num)

Description copied from interface: Animatable

Returns an event that is somewhere between the start and end points of a change blind transition, depending on the display_step and the number of steps involved in the transition. Only need to implement if the application uses change blind transitions.

Specified by:

changeblindTransStep in interface Animatable

Parameters:

prev_event - the previous event sent to this Output (null if the new event is the first).

new_event - the new event to be displayed on the Output.

step_num - a number indicating the display order of the event returned if the Transition is creating a set of events.

Returns:

Event

makeawareTransStep

public Event makeawareTransStep(Event prev_event,
                                Event new_event,
                                int step_num)

Description copied from interface: Animatable

Returns an event that is somewhere between the start and end points of a make aware transition, depending on the display_step and the number of steps involved in the transition. Only need to implement if the application uses make aware transitions.

Specified by:

makeawareTransStep in interface Animatable

Parameters:

prev_event - the previous event sent to this Output (null if the new event is the first).

new_event - the new event to be displayed on the Output.

step_num - a number indicating the display order of the event returned if the Transition is creating a set of events.

Returns:

Event

interruptTransStep

public Event interruptTransStep(Event prev_event,
                                Event new_event,
                                int step_num)

Description copied from interface: Animatable

Returns an event that is somewhere between the start and end points of a interrupt transition, depending on the display_step and the number of steps involved in the transition. Only need to implement if the application uses interrupt transitions.

Specified by:

interruptTransStep in interface Animatable

Parameters:

prev_event - the previous event sent to this Output (null if the new event is the first).

new_event - the new event to be displayed on the Output.

step_num - a number indicating the display order of the event returned if the Transition is creating a set of events.

Returns:

Event

alternateStep

public Event alternateStep(Event prev_event,
                           Event new_event,
                           int step)

Description copied from interface: Animatable

Returns an event that represents the "alternate" or "opposite" of what is displayed by the other transition methods in order to create a "flashing" effect. For example, if a text is displayed on a ticker, the alternateStep might be to delete all the text. For an interrupt transition, the effect would be text flashing between the the new event text (returned by endTransition) and no text (returned by alternateStep).

Specified by:

alternateStep in interface Animatable

Parameters:

prev_event - the previous event sent to this Output (null if the new event is the first).

new_event - the new event to be displayed on the Output.

step - a number indicating the display order of the event returned if the Transition is creating a set of events.

Returns:

Event
