public class simple_transition

extends transition

This is a version of the transition object which knows how to talk to objects which are of type simple_animatable.

Field Summary

protected simple_animatable

_simple_target This is the object we are going to animate.

Constructor Summary

simple_transition(simple_animatable i, time_interval t, trajectory j)
Create a simple transition given a simple_animatable object, a time interval, and a trajectory.

Method Summary

void	end(event e, java.lang.Object user_info) Send the end message to the interactor.
simple_animatable	simple_target() The simple target of this transition is the simple_animatable object with whom we are communicating.
void	start(event e, java.lang.Object user_info) Start a transition.
void	step(event e, java.lang.Object user_info, long current_time) Perform a step...

Field Detail

_simple_target

protected simple_animatable _simple_target

This is the object we are going to animate. The "target" of this transition is null since we are not using the animatable interface.

Constructor Detail

simple_transition

public simple_transition(simple_animatable i,
                         time_interval t,
                         trajectory j)

Create a simple transition given a simple_animatable object, a time interval, and a trajectory.

Parameters:

simple_animatable - i the target of the animation or transition

time_interval - t the time interval over which this transition occurs

trajectory - j the trajectory over which this transition is mapped

Method Detail

simple_target

public simple_animatable simple_target()

The simple target of this transition is the simple_animatable object with whom we are communicating.

start

public void start(event e,
                  java.lang.Object user_info)

Start a transition. This is where the work gets done of calling the start_transition function on the interactor.

Parameters:

event - e the animation event that caused things to get going

Object - user_info the object passed to the animation agent when the animatable joined its focus set

Overrides:

start in class transition

step

public void step(event e,
                 java.lang.Object user_info,
                 long current_time)

Perform a step... this sends the transition_step message to the interactor.

Parameters:

event - e the animation event for this step

Object - user_info the object passed to the animation agent when the animatable joined its focus set

long - current_time the time it is "now" for this time step

Overrides:

step in class transition

end

public void end(event e,
                java.lang.Object user_info)

Send the end message to the interactor.

Parameters:

event - e the animation event for this step

Object - user_info the object passed to the animation agent when the animatable joined its focus set

Overrides:

end in class transition
