I discovered a possible gap in the MethodHandles API. Say I want to create an exception handler that does nothing but ignore the exception. The target handle is a method that looks like this:
void foo(String) I have my "target" handle pointing at foo. I want to catch all Throwable and ignore them, so I would build up a method handle chain that does the following (top-down) 1. receives arguments (Throwable, String) and returns void 2. drops both arguments 3. ??? There's no endpoint I can attach it to for a "no-op" void return. "constant" doesn't work because it returns a value, and explicitly forbids void return type. "identity" doesn't work because it returns a value and receives one argument. What I need here is something like MethodHandles.constant, but that takes no arguments and has a void return. MethodHandles.nop anyone? I could filterReturn, but I still would have to attach it to an external method...there's no way to create a filter that returns void entirely with method handles. Am I missing something? - Charlie _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
