flash syntax

[softeye]

hi,

I need help to understand the basic syntax.
like:
iXpos = (mouseX <= lo) ? xhi : xlo;
and
(this.trend == 0 ) ? (checkBoundary() ? 0.25 : -0.25) : (this.trend);

what "?" and ":" stands for

its kind of tricky to search for specific character syntax?:sigh:

thx,
Daniel

ternary operator

Shorthand if statement.

if(condition) doSomething
else doSomethingElse

is the same as

condition ? doSomething : doSomethingElse

[Felixz]

var sth:String = otherVarIsNotNull ? otherVarIsNotNull : "var Was Null";

[Shaedo]

of course a great summary of all of these things and more is available here:
