Hi all, I'm using GWT 2.7.0-beta and I'm experimenting an integration with
some existing JavaScript.
I wrote a wrapper:
@JsType
public interface ExistingJavaScriptObject {
ExistingJavaScriptObject function(String param, Object callback);
}
It's the same pattern used in many JS Frameworks and I need to pass a
callback as the second param.
For that I wrote a SAM interface
@JsType(prototype = "Function")
public interface FunctionCall<P, R> {
R function(P param);
}
But I don't know how to create a function object from this if not with a
trampoline method in JNSI:
private static native <P,R> JavaScriptObject i2f(FunctionCall<P, R>
functionCall) /*-{
return function(param) {
return functionCall.@FunctionCall::function(Ljava/lang/Object;)(param);
};
}-*/;
I think I'm missing the point, here in GWT 2.7 I can't use lambdas so I
think there must be a smarter way to pass a function to a wrapper
JavaScript object.
Any hints ? No better options ??
Thank you.
