You could have your custom components implement a custom interface like
IValidatable that requires the validate() function, and then check
whether the class implements that interface by using the following:
if( yourComponent is IValidatable)
{
// Your code here
}

Subject: [flexcoders] How to see if method is implemented in class
Hi,
I've got a problem I'm trying to resolve concerning validating a page
before submitting it to the server. I have a way to recursively get
each child on the page. However, I can't figure out a way to see if
the child has the validate() method implemented. Most of the
components are extended from TextInputs, ComboBox, etc, where I've
integrated a validator into each one that is custom for that type. So
my custom components will have a validate method, however, other
components - like Images, Buttons, etc - on the page don't have a
validate method. Is there a way to test that a method exists, before
trying to call it and causing an exception?
Thanks,
John
