Subject: [flexcoders] Determine if a Class implements an Interface

Hi all,

I often use

if (obj is MyClassOrInterface)
{
// do whatever
}

but it appears that only works with Instances not Classes. With just a
Class, how can I tell if that class implements a particular interface
or is of a particular base type? Do I have to create an instance of
it and check the instance? I'm sure there must be another way...

thanks in advance,
Thunder

if (currentDomain.hasDefinition(sPropClass))
{
psClass = Class(currentDomain.getDefinition(sPropClass));
}

// below statement doesn't work!
if ( (psClass != null) && (psClass is IPropertySheet) )
{
// make a new one of these classes.
}
