public interface Bax{
public String getValue();
}
public class Bar implements Bax{
String size;
public String getValue(){return size;}
}
public class Foo implements Ba... OH WAIT!!
You have one class returning String, and another returning int.
I was going to say you need to use interfaces more, and the compiler WILL
generate singleton functions and add them to prototypes as needed, but you
have different data types.
Just because it's the same in javascript to return x.a, does NOT make it the
same in Java, and like it or not, the strength of GWT is that it is
hierarchial, object-oriented javascript. You CAN'T inline these functions,
because when you just call getSize() or getName(), it will just return the
variable, but it you add more functions to Bar like
public int OR(Bar a){
return a.size()|this.size();
}
The compliler can generate function xYz(b){ return this$static.a | b.a;}
This is NOT legal for Strings anywhere, and any prototypes inline to take
advantage of compiler naming conventions would result in HUGE permutation
chains to determine what areas of javascript can be melted into single
functions, but this is not a worthwhile price to pay for file sizes today...
...Cos in the world of tomorrow, next gen browsers like Firefox and Chrome
actual use class-based internal optimizations to make your typeless
javascript take advantage of the strongly-typed applications by relaxing how
they treat data. In old JS, any data could be any other data, and the
browser's got to perform type-checking for every + operation, for every new
and every x.apply(y);... In new JS, when your app uses a certain expando
for numbers-only, or string-only or jsObjects only, it will adapt and stop
running redundant checks when data will never be anything but an int...
Trust me, an old JS library I wrote in FF2 would run slow for a while, but
after a few page reloads, my animations actually speeded up, and benchmarks
reported slight but noticeable improvements around 15% after the first
run...
