JsFunction

public interface JsFunction implements JsObject

Represents a JavaScript function that can be passed between Java and JavaScript as a method argument or a return value. The function lifetime is bound to the lifetime of the frame this function belongs to. When the owner frame is unloaded, all the JavaScript objects are automatically disposed. An attempt to access a disposed JavaScript object will result in IllegalStateException.
