Type casting the returned value of a method.

Hi,

How do you type cast the returned value of a method so that you can avoid creating a temporary variable. Here's an example:

panel.getComponent(i).(OnOffButton)setState('0');

I know that the component returned by panel.getComponent(i) will be of type OnOffButton. I want to avoid:

OnOffButton btn = (OnOffButton) panel.getComponent(i); btn.setState('0');

Is there a way around this?

Thanks,

Justin

Hi,

You may try following code:

((OnOffButton) panel.getComponent(i); btn.setState('0')).setState('0');

Thanks

Hi,

That doesn't work. (Also, i'm trying to avoid creating the btn variable in the first place).

Thanks
