I see, so then you would do this:
// user defined function. user should be able to define or redefine
this function
private function
defaultExternalInterfaceFunction(value:Boolean):Boolean {
return true;
}
private var _externalInterfaceFunction:Function =
defaultExternalInterfaceFunction

function
so is it possible to define the default function if it is not defined?
lets say the user does not define the function, i would want it to fall
back on a default behavior.

Wish we could, but you can't. So it is:
private var _externalInterfaceFunction:Function

In the Tree component you can assign a function to the labelFunction
property. I would like to do that in my component but I'm only receiving
errors. What I want is exactly the same as the Tree component. Here is
the closest I could get:
In my component class file:
// user defined function. user should be able to define or redefine
this function
private function _externalInterfaceFunction(value:Boolean):Boolean {
return true;
}
// setter that lets user override default function with user defined
function
public function set externalInterfaceFunction(value:Function) {
if (value!=null) {
_externalInterfaceFunction = value;
}
}
