Re: LinkLayer and Timer

Hi Don,

Thanks for your answer.

I beg your pardon for bothering you with this simple question but, when I
tried to call the LinkLayer.doPrepare() from the Timer layer I got the
following error in the compilation:

Non-static method doPrepare() cannot be referenced from a static context

I tried to identify why the Timer Layer(DayNightLayer) is considered STATIC
without success and afterwards I tried to change the doPrepare() method to
STATIC in the LinkLayer, but other related variables must be changed to
static too.

Do you know what is wrong?

Regards,

Orlando
