  • Are reference attributes destroyed when class is destroyed in C++?

    - by Genba
    Suppose I have a C++ class with an attribute that is a reference: class ClassB { ClassA &ref; public: ClassB(ClassA &_ref); } Of course, the constructor is defined this way: ClassB::ClassB(ClassA &_ref) : ref(_ref) { /* ... */ } My question is: When an instance of class 'ClassB' is destroyed, is the object referenced by 'ClassB::ref' also destroyed?

  • Does a syntax for this exist? In any language?

    - by Michael
    It seems pretty common to me to have an argument, in a dynamically typed language that is either an Object or a key to lookup that object. For instance when I'm working with a database I might have a method getMyRelatedStuff(person) All I really need to lookup the related stuff is the id of the person so my method could look like this in python: def getMyRelatedStuff(person_or_id): id = person_or_id.id if isinstance(person,User) else person_or_id #do some lookup Or going the other direction: def someFileStuff(file_or_name): file = file_or_name if hasattr(file,'write') else open(file_or_name)

  • Unusual Template Behavior with XSL

    - by bobber205
    Experiencing some very odd behavior with, what should be, a very simple use of XSL and XSLT. Here's a code sample. <xsl:template match="check"> <div class="check"> <xsl:apply-templates mode="check"> <xsl:with-param name="checkName">testVariable</xsl:with-param> </xsl:apple-templates> </div> </xsl:template> The template called above <xsl:template match="option" mode="check"> <xsl:param name="checkName" /> <div class="option"> <input type="checkbox"> </input> <label> testText </label> </div> </xsl:template> Pretty simple right? It should, for each instance of a instance in the XML create a checkbox in a with a hard coded label. However, what I'm getting is <div class="check"></div> <div class="option>Checkbox stuff here</div> <div class="option>Checkbox stuff here</div> <div class="option>Checkbox stuff here</div> <div class="option>Checkbox stuff here</div> <div class="check"></div> <div class="option>Checkbox stuff here</div> <div class="option>Checkbox stuff here</div> <div class="option>Checkbox stuff here</div> <div class="option>Checkbox stuff here</div> Here's some sample XML <check><option key="1"/><option key="0"/><option key="0"/><option key="0"/><option key="0"/></check> Anyone know what's going on? :D

  • creating proxy object in groovy

    - by IttayD
    Hi, I am looking for how to write a method that accepts some value and returns a proxy to that value where the underlying value can be retrieved with an accessor: def p = toProxy(1) assert p == 1 assert p * 2 == 2 assert p.underlying == 1 def p2 = toProxy(objWithMethodFoo) p2.foo() p2.underlying.foo() I want to do this per object instance (not for all objects of some class) and without the need to use special 'use' constructs.

  • How to disconnect an existing ruby sequel connection to a database?

    - by MG
    I mean the one which was previously established as DB = Sequel.sqlite('my_blog.db') or DB = Sequel.connect('postgres://user:password@localhost/my_db') or DB = Sequel.postgres('my_db', :user => 'user', :password => 'password', :host => 'localhost') or etcetera. The Sequel::Database class has no public instance method called "disconnect" or so though it has "connect" one. Maybe somebody already faced that problem. I would appreciate any idea.

  • Is it possible to control Visual Studio exception handling from the debugged code itself?

    - by mark
    Dear ladies and sirs. I am wondering if it is possible to control the Visual Studio exception handling options from the code itself. For instance, I would like to turn off stopping on FCE for a certain piece of code, that generates many FCE, however, I would like it to be active for all the other code. Is it possible to do it from code? Something like this: visualStudio.DoNotStopOnFCE() try { // some code generating many FCE } catch {} visualStudio.StopOnFCE() Thanks.

    - by Lakshmie
    I would like to know as to what will happen to the thread which has been created by an activity and the device is rotated. I have observed that the onDestroy method is called when this happens. Will the thread be killed too? If the thread is not killed, how can I reassociate the thread with the activity as a new instance of the activity is created on rotation. Thanks, Lakshmie

  • Java, user input to the command line when using Runtime.getRuntime().exec(command);

    - by user1557354
    I dont think this is possible, but I have been using: Process p = Runtime.getRuntime().exec(command); to run commands on the command line, but now I have come accross a situation where the command I am running part way through will ask for some user input, for example a username. This can not be resolved by a argument to the command that is being exec, is there any way I can pass the username to the same command line instance and continue? Thanks in advance.

  • C# - Does foreach() iterate by reference?

    - by sharkin
    Consider this: List<MyClass> obj_list = get_the_list(); foreach( MyClass obj in obj_list ) { obj.property = 42; } Is 'obj' a reference to the corresponding object within the list so that when I change the property the change will persist in the object instance once constructed somewhere?

  • How can I check the network connection type using the Windows API?

    - by Jufkey
    How can I programmatically retrieve the current connection type (eg. LAN or Direct connection)? InternetGetConnectedState() isn't very reliable. For instance, I'm connected to a wireless network, but ConTypeRet is 18, which is INTERNET_CONNECTION_LAN & INTERNET_RAS_INSTALLED. Isn't there any way to make sure that ConTypeRet is either INTERNET_CONNECTION_LAN or INTERNET_CONNECTION_MODEM?

    I have this object which is an instance of a superclass. I want to know which subclass that object really is, so that I can decide what to do with it. There is this getClass() method but it's apparently not used for comparison issues. How can I get the sub-type of my object?
