Hi,
Looks like that some javascript libraries are checking on the argument
length of the callbacks that are passed to them.
So for example D3 bisector can take a function with one or two arguments.
If it is one then it is an accessor if it is two then it is a comparator.
I searched on github issues. Should I report it?
The following snippet demonstrates the problem. The Function.length should
be 1 and not 0.
@JsFunction
public static interface SomeFunction {
public double call(double x);
}
/** * This is the entry point method. */
@Override
public void onModuleLoad() {
final SomeFunction y = new SomeFunction() {
@Override
public double call(double x) {
return 2 * x;
}
};
DomGlobal.console.log(y);
return; }
