Thanks Paul, Nino and Thomas
Paul: yes I suppose that too, but interfaces do not implement methods, so I
thought it is strange.
Nino: I do not want to make object wrapping as you suggested because I want
my library user's to use the overlay types directly for a zero-overhead
API. Your approach however would make this kind of Java API much more
confortable to Java users.
Thomas, thanks. Yes I'm using .cast() a lot, it is much more confortable
than java casting. Also I have designed this YUI java API to be the most
similar to the native javascript API. So code using mine YUIGWT will look
strange to java programmers, for example, a js literal object definition :
in javascrpt:
var p = {name: "seba", age: 28}
in java:
Person p = Person.create().name("seba").age(28);
