Expanding the State Design: Adding States | 379To test the additional pause class, all you need to do in the test class is add another
button instance. With three buttons, a little more positioning thought has to go into
it, but expanding the State design pattern is very easy. All the changes for adding the
additional button are on lines 45-48 and 53. So just edit theTestVid.asfile as shown
in Example 10-19, and save it as TestPause.as.
this.state=state;
}
public function getState( ):State
{
return state;
}
public function getPlayState( ):State
{
return this.playState;
}
public function getStopState( ):State
{
return this.stopState;
}
public function getPauseState( ):State
{
return this.pauseState;
}
}
}
