java - Why is there commented-out code in native method? -
recently, i've seen lot of methods "native" keyword. seems common have, what seems like, commented out code.
public native foo(arg, arg) /*-{ var foo = some.method(arg); return foo; }-*/;
i don't understand what commented-out portion or why it's commented out. while i've thought commented out code. i'm starting see in more projects (for instance, it's in gwt source code).
is commented-out code significant in way don't understand? i've read native keyword, , understand means , how it's used in basic sense. it's confusing see "commented-out code" often.
can explain comments. comments? significant?
[update] question commented out portion. starting see enough thought there significance missing. annotation, instance. wanted clear onwhy there commented out sections of code littered over.
because gwt code compiled in 2 distinct part : java server part , javascript client one.
the comment syntax in native methods
/*-{ javascript code }-*/
is gwt specific way write native javascript in gwt code.
see jsni
