  • Returning an anonymous class that uses a final primitive. How does it work?

    - by Tim P
    Hi, I was wondering if someone could explain how the following code works: public interface Result { public int getCount(); public List<Thing> getThings(); } class SomeClass { ... public Result getThingResult() { final List<Thing> things = .. populated from something. final int count = 5; return new Result { @Override public int getCount() { return count; } @Override public List<Thing> getThings(); return things; } } } ... } Where do the primitive int , List reference and List instance get stored in memory? It can't be on the stack.. so where? Is there a difference between how references and primitives are handled in this situation? Thanks a bunch, Tim P.

  • Problems with passing an anonymous temporary function-object to a templatized constructor.

    - by Akanksh
    I am trying to attach a function-object to be called on destruction of a templatized class. However, I can not seem to be able to pass the function-object as a temporary. The warning I get is (if the comment the line xi.data = 5;): warning C4930: 'X<T> xi2(writer (__cdecl *)(void))': prototyped function not called (was a variable definition intended?) with [ T=int ] and if I try to use the constructed object, I get a compilation error saying: error C2228: left of '.data' must have class/struct/union I apologize for the lengthy piece of code, but I think all the components need to be visible to assess the situation. template<typename T> struct Base { virtual void run( T& ){} virtual ~Base(){} }; template<typename T, typename D> struct Derived : public Base<T> { virtual void run( T& t ) { D d; d(t); } }; template<typename T> struct X { template<typename R> X(const R& r) { std::cout << "X(R)" << std::endl; ptr = new Derived<T,R>(); } X():ptr(0) { std::cout << "X()" << std::endl; } ~X() { if(ptr) { ptr->run(data); delete ptr; } else { std::cout << "no ptr" << std::endl; } } Base<T>* ptr; T data; }; struct writer { template<typename T> void operator()( const T& i ) { std::cout << "T : " << i << std::endl; } }; int main() { { writer w; X<int> xi2(w); //X<int> xi2(writer()); //This does not work! xi2.data = 15; } return 0; }; The reason I am trying this out is so that I can "somehow" attach function-objects types with the objects without keeping an instance of the function-object itself within the class. Thus when I create an object of class X, I do not have to keep an object of class writer within it, but only a pointer to Base<T> (I'm not sure if I need the <T> here, but for now its there). The problem is that I seem to have to create an object of writer and then pass it to the constructor of X rather than call it like X<int> xi(writer(); I might be missing something completely stupid and obvious here, any suggestions?

  • Why is an anonymous inner class containing nothing generated from this code?

    - by Andrew Westberg
    When run through javac on the cmd line Sun JVM 1.6.0_20, this code produces 6 .class files OuterClass.class OuterClass$1.class OuterClass$InnerClass.class OuterClass$InnerClass2.class OuterClass$InnerClass$InnerInnerClass.class OuterClass$PrivateInnerClass.class When run through JDT in eclipse, it produces only 5 classes. OuterClass.class OuterClass$1.class OuterClass$InnerClass.class OuterClass$InnerClass2.class OuterClass$InnerClass$InnerInnerClass.class OuterClass$PrivateInnerClass.class When decompiled, OuterClass$1.class contains nothing. Where is this extra class coming from and why is it created? package com.test; public class OuterClass { public class InnerClass { public class InnerInnerClass { } } public class InnerClass2 { } //this class should not exist in OuterClass after dummifying private class PrivateInnerClass { private String getString() { return "hello PrivateInnerClass"; } } public String getStringFromPrivateInner() { return new PrivateInnerClass().getString(); } }

  • How to create a anonymous proxy?

    - by Rakesh Juyal
    I want to create a proxy server anonymous proxy . I googled it and even found some tutorial but those were in PHP. If somebody is having tutorial of proxy server anonymous proxy creation in java then please post it here Or simply let me know what approach should i follow to create a proxy server anonymous proxy. [ i will be using Tomcat { if that matters for your answer } ] Thanks Edit i guess i was not clear in stating what i require. Actually i am trying to develop a site like 'http://proxyug.com/' . If none of you were getting what i asked, then it certainly means such sites are not known as 'proxy server' they must be called something else. :)

  • Anonymous code blocks in Groovy

    - by piepera
    Is there a way to use anonymous code blocks in Groovy? For example, I'm trying to translate the following Java code into Groovy: { int i = 0; System.out.println(i); } int i = 10; System.out.println(i); The closest translation I can come up with is the following: boolean groovyIsLame = true; if (groovyIsLame) { int i = 0; System.out.println(i); } int i = 10; System.out.println(i); I know anonymous code blocks are often kind of an antipattern. But having variables with names like "inputStream0" and "inputStream1" is an antipattern too, so for this code I'm working on, anonymous code blocks would be helpful.

  • Windows 2003 hidden anonymous shares with IP restriction

    - by Tomas
    Hello, I have created anonymous(everyone account) "hidden" shares on Windows 2003 to let our ASP.NET application access it from another server without credentials. I have added $ to share name to hide it from other users, but actually this is not solution because such shares can be easily discovered by other OS or some tools on Win. Can I restrict shared folder access by IP? Regards, Tomas

    Anonymous Indonésie et Australie bientôt en cyber guerre ? Le ton monte entre les membres du collectif Les révélations d'Edward Snowden sèment de plus en plus de trouble aux seins des coalitions.

  • IIS 7.5 - Remove the pipe character from usernames for virtual hosts

    - by glasnt
    Currently I have a setup with a virtual FTP site in IIS 7.5 that requires the following authentication details for the anonymous account: Host: ftp.mydomain.com User: ftp.mydomain.com|anonymous Pass: <none> I have multiple FTP accounts setup on this same server. I know that this means I need to specify the domain in the username to let IIS know what I need site to authenticate against, but is it possible to make the username only be anonymous? Would I have to create a user by that name in the windows users and groups area to be and specifically link it there?

  • How to setup anonymous access in WinSSHD

    - by Shrike
    I have a Windows server (Win2008R2) with WinSSHD installed. I need to allow anonymous access to a particular folder on the server. Actually it's a git repositiory for bower registy but it doesn't matter. I want WinSSHD allow me to connect to an endpoint like "ssh://[email protected]/" I've created a virtual user "bower" with password only auth. No keys. But if I leave empty password then WinSSHD doesn't allow connection with error "Incorrect virtual account password". How to setup a SSH access without any authentication?

  • Bash: create anonymous fifo

    - by Adrian Panasiuk
    We all know mkfifo and pipelines. The first one creates a named pipe, thus one has to select a name, most likely with mktemp and later remember to unlink. The other creates an anonymous pipe, no hassle with names and removal, but the ends of the pipe get tied to the commands in the pipeline, it isn't really convenient to somehow get a grip of the file descriptors and use them in the rest of the script. In a compiled program, I would just do ret=pipe(filedes); in Bash there is exec 5<>file so one would expect something like "exec 5<> -" or "pipe <5 >6" -is there something like that in Bash?

  • How to refactor this Javascript anonymous function?

    - by HeavyWave
    We have this anonymous function in our code, which is part of the jQuery's Ajax object parameters and which uses some variables from the function it is called from. this.invoke = function(method, data, callback, error, bare) { $.ajax({ success: function(res) { if (!callback) return; var result = ""; if (res != null && res.length != 0) var result = JSON2.parse(res); if (bare) { callback(result); return; } for (var property in result) { callback(result[property]); break; } } }); } I have omitted the extra code, but you get the idea. The code works perfectly fine, but it leaks 4 Kbs on each call in IE, so I want to refactor it to turn the anonymous function into a named one, like this.onSuccess = function(res) { .. }. The problem is that this function uses variables from this.invoke(..), so I cannot just take it outside of its body. How do I correctly refactor this code, so that it does not use anonymous functions and parent function variables?

  • trouble setting up anonymous login in ejabberd

    - by sofia
    Hi, In ejabberd.cfg I have the following {host_config, "thisislove-MacBook-2.local", [{auth_method, [internal, anonymous]}, {allow_multiple_connections, false}, {anonymous_protocol, both}]}. but when using speeqe javascript client (speeqe.com) to connect, I see it sends <body rid='1366284187' xmlns='http://jabber.org/protocol/httpbind' to='thisislove-macbook-2.local' xml:lang='en' wait='60' hold='1' window='5' content='text/xml; charset=utf-8' ver='1.6' xmpp:version='1.0' xmlns:xmpp='urn:xmpp:xbosh'/> and the server responds with <body xmlns='http://jabber.org/protocol/httpbind' sid='f89bf034b02fa6b884bb0c55be3f1f69e45e3866' wait='60' requests='2' inactivity='30' maxpause='120' polling='2' ver='1.8' from='thisislove-macbook-2.local' secure='true' authid='353072658' xmlns:xmpp='urn:xmpp:xbosh' xmlns:stream='http://etherx.jabber.org/streams' xmpp:version='1.0'><stream:features xmlns:stream='http://etherx.jabber.org/streams'><mechanisms xmlns='urn:ietf:params:xml:ns:xmpp-sasl'><mechanism>DIGEST-MD5</mechanism><mechanism>PLAIN</mechanism></mechanisms><register xmlns='http://jabber.org/features/iq-register'/></stream:features></body> Notice the mechanisms, DIGEST-MD5 & PLAIN. If I'm not mistaken it should have ANONYMOUS as a mechanism as well. So what happens is that speeqe simply terminates the connection. As such I'm thinking i must be missing something in the anonymous configuration or the muc config. In the mod_muc configg, I have {mod_muc, [ %%{host, "conference.@HOST@"}, {access, muc}, {access_create, muc}, {access_persistent, muc}, {access_admin, muc_admin}, {max_room_name, 190}, {max_room_desc, 190}, {max_users, 500} ]} So what am I missing? Thanks
