selector

Got some quick questions on using a non blocking selector - answering any of the below would be greatly appreciated: I have just ben learning about the selector (java NIO model) and want to clarify some facts. Picked up most of the key points from tutorials as well as the SO question: Java NIO: Selectors so: from the question linked above, a Server socket channel is registered to listen for accept, when accepted a channel is registered for read and once read it is registered for write. How does it then go back into listening for an accept? I mean there appears to be no repeated call to a

We all know that using asyncio substantially improves the performance of a socket server, and obviously things get even more awesome if we could take advantage of all cores in our cpu (maybe via multiprocessing module or os.fork() etc.) I'm now trying to build a multicore socket server demo, with a asynchronous socket server listening on each core and all binding to one port. Simply by creating a async server and then use os.fork() , let processes work competitively. However the single-core-fine code runs into some trouble when I'm trying to fork. Seems like there's some problem with

I have some Objective-C++ code like this: // header @interface MyObjcClass - (void) myMethod: (NSString *) text; @end // implementation @implementation MyObjcClass - (void) myMethod: (NSString *) text { someInternalObject->useWstring(nsStringToWstring(text)) } std::wstring nsStringToWstring(const NSString * text) { NSData * data = [text dataUsingEncoding: NSUTF32LittleEndianStringEncoding]; // and then some other stuff irrelevant to this question return std::wstring(pointerToNewString, pointerToNewString + stringLength); } @end Straightforward so far; seems fine to me. And works great when

I am trying to overwrite an existing component in angular. My original component is: @Component({ selector: 'app-orginal', templateUrl: './orginal.component.html', styleUrls: ['./orginal.component.css'] }) export class OrginalComponent implements OnInit { } in the app.component.html I use the original component like that: <app-orginal></app-orginal> What you would like to do is overwrite the original component with the mock component. This is my mock component: @Component({ selector: 'app-mock-of-orginal', templateUrl: './mock-of-orginal.component.html', styleUrls: ['./mock-of-orginal

I want to invoke a selector of a method that has the usual NSError** argument: -(int) getItemsSince:(NSDate *)when dataSelector:(SEL)getDataSelector error:(NSError**)outError { NSArray *data = nil; if([service respondsToSelector:getDataSelector]) { data = [service performSelector:getDataSelector withObject:when withObject:outError]; // etc. ... which the compiler doesn't like: warning: passing argument 3 of 'performSelector:withObject:withObject:' from incompatible pointer type Is there any way around this short of encapsulating the pointer in an object? Check out NSInvocation , which lets you
