Hi all.
I'm playing with GWT overlay types for learning better ways of overlaying
and working with them more agile. In particular I found that JSO setters
methods that return 'this' for method chaining are a good way of defining
an object state in a single Java statement, just like they are done in
JavaScript. I written about this in
http://cancerberonia.blogspot.com/2012/12/guidelines-for-writing-gwt-overlay-types.html
This setters methods look like this:
public native final MyJSO color(String val) /*-{
this["color"]=val;
return this;
}-*/;
So I can define an object in a single Java Statement like
MyJSO my1 = MyJSO.create().color("red").age(14);
I feel very confortable with that approach and using it on my GWT projects
based on JSOs. But to my surprise (thanks to IRC user niloc132), these
setters are not inlined in the GWT compiler JavaScript output. Please, read
last part of my blog post "About Performance". For each setter a JavaScript
function is defined and called: the JSNI code is not inlined. So this is
not a zero overhead solution (as my libraries promise).
I tried different approachs for defining these setters, but with the same
results in all cases. My question is, can I force the GWT compiler somehow
to inline some of mine JSNI methods, perhaps with some annotation ? Do
somebody have any suggestions for making setters returning 'this' to be
inlined in javascript output instead of creating and calling javascript
functions in javascript generated code ?
Regards and thanks in advance.
