check if variable is set (custom object)
Oct 13th, 2008, 1:15pm  
I'm quite new to Processing and Java but generally know how to program.
I have my own class Palette.
and the variable borderPalette which contains an Object of that Class. So how do I check if the variable is set to set it in case it hasn't been set yet? (I hope this sentence makes sense)

Palette borderPalette;
if(borderPalette) borderPalette = shorten(palettes);
