Hi, When working in a more functional style, the null checks for adaptTo() are not rally nice, and I typically wrap the result of adaptTo() just into an Optional by my own.
String propValue = Optional.ofNullable(resource.adaptTo(ValueMap.class)).map(vm -> vm.get("property").orElse(() -> {return "defaultValue"}); it would be nice if I could write it like this: String propValue = resource.adaptTo(ValueMap.class).map(vm -> vm.get("property").orElse(() -> {return "defaultValue")}); It would require an extension to the Adaptable interface, but that could be implemented as default method, so it's signature would not change. While I can do that in my code as well, it would be good to have it in the Adaptable interface as well; it can encourage others to use Optional instead of explicit Null Checks; and the Null checks are often missing :-( WDYT? -- Cheers, Jörg Hoh, http://cqdump.wordpress.com Twitter: @joerghoh
