How to convert existing JavaScriptObject to java primitive type in GWT?

Question

Suppose I have a link to an existing JavaScriptObject that contains a primitive type, for example an int value, how can I get this int value?

Answer 1

Use JSNI to "adapt" between GWT Java and basic Javascript: more specifically, use a method cast()to adapt to the type you want. You can subsequently "repackage" the object to any Java primitive that you want / can.
