  • Python decorator question

    - by nsharish
    decorator 1: def dec(f): def wrap(obj, *args, **kwargs): f(obj, *args,**kwargs) return wrap decorator 2: class dec: def __init__(self, f): self.f = f def __call__(self, obj, *args, **kwargs): self.f(obj, *args, **kwargs) A sample class, class Test: @dec def disp(self, *args, **kwargs): print(*args,**kwargs) The follwing code works with decorator 1 but not with decorator 2. a = Test() a.disp("Message") I dont understand why decorator 2 is not working here. Can someone help me with this?

  • Why does C# allow abstract class with no abstract members?

    - by fatcat1111
    The C# spec, section 10.1.1.1, states: An abstract class is permitted (but not required) to contain abstract members. This allows me to create classes like this: public abstract class A { public void Main() { // it's full of logic! } } This is really a concrete class; it's only abstract in so far as one can't instantiate it. If inheritors don't actually have to provide implementation, then why call it abstract?

  • How to write sum calculation based on ria service?

    - by KentZhou
    When using ria service for SL app, I can issue following async call to get a group of entity list. LoadOperation<Person> ch = this.AMSContext.Load(this.AMSContext.GetPersonQuery().Where(a => a.PersonID == this.performer.PersonID)); But I want to get some calculation, for example, sum(Commission), sum(Salary), the result is not entity, just a scalar value. How can I do this?

  • JNI cached jclass global reference variables being garbage collected?

    - by bubbadoughball
    I'm working in the JNI Invocation API, calling into Java from C. I have some upfront initialization to cache 30+ Java classes into global references. The results of FindClass are passed into NewGlobalRef to acquire a global reference to the class. I'm caching these class variables to reuse them later. I have 30+ global references to classes (and 30+ global methodIDs for the class constructors). In the following sample, I've removed exception handling as well as JNI invocation for the purpose of shortening the code snippet. My working code has exception checks after every JNI call and I'm running with -Xcheck:jni. Here's the snippet: jclass aClass; jclass bClass; jmethodID aCtor; jmethodID bCtor; void getGlobalRef(const char* clazz, jclass* globalClass) { jclass local = (*jenv)->FindClass(jenv,clazz); if (local) { *globalClass = (jclass) (*jenv)->NewGlobalRef(jenv,local); (*jenv)->DeleteLocalRef(jenv,local); } } methodID getMethodID(jclass clazz, const char* method, const char* sig) { return (*jenv)->GetMethodID(jenv,clazz,method,sig); } void initializeJNI() { getGlobalRef("MyProj/Testclass1", &aclass); getGlobalRef("MyProj/Testclass2", &bclass); . . aCtor = getMethodID(aclass,"<init>","()V"); bCtor = getMethodID(bclass,"<init>","(I)V"); } The initializeJNI() function sets the global references for jclasses and method IDs for constructors as well as some jfieldID's and some initialization of C data structures. After initialization, when I call into a JNI function using some of the cached jclasses and ctor jmethodIDs, I get a bad global or local reference calling reported from the -Xcheck:jni. In gdb, I break at the last line of initializeJNI(), and print all jclasses and jmethodIDs and the ones causing problems look to have been turned into garbage or garbage-collected (i.e. 0x00 or 0x06). Is it possible for global references to be gc'ed? Any suggestions?

  • JSP application scope objects in Java library

    - by FrontierPsycho
    I am working on a preexisting web application built with JSP, which uses an external Java library. I want to make some JavaBeans that were instantiated with jsp:useBean tags available to the Java code. What would be a good practice to do that? I suppose I can pass the objects in question to every function call that requires them, but I'd like to avoid that.

  • Dos SET command advanced /A features resource

    - by user66001
    Have done quite a bit of searching for a guide (of any substance) for the above to no avail. Can anyone refer me to one? In the present tense however, I am trying to understand the below code example, which returns a two digit representation of the month, that corresponds to the 3 character month name set in v: SET v=May SET map=Jan-01;Feb-02;Mar-03;Apr-04;May-05;Jun-06;Jul-07;Aug-08;Sep-09;Oct-10;Nov-11;Dec-12 CALL SET v=%%map:*%v%-=%% SET v=%v:;=&rem.% ECHO.%v%

  • What are All the Ways a Programmer Could use PHP to Send an Email?

    - by Alan Storm
    I'm looking for a list of built in PHP functions that a programmer could use to send an email. The obvious answer here is mail(), but I'm also looking for a list of functions someone might use to manually open a connection to an MTA, or spawn a process on the local machine which might in turn send an email using sendmail, postfix, etc. The context here is I want to scan a large, unknown codebase for code that's sending out email (because we already located a call to mail(), and that's not doing it)

  • Enity framework not loading relationship even when using include

    - by dilbert789
    I have this code: Category selectedCategory = (from c in DB.Category.Include("SubCategory") join a in DB.Accessory on c.AccCatUID equals a.Category.AccCatUID where a.AccUID == currentAccessory.AccUID select c).FirstOrDefault(); It works fine, selectedCategory gets populated as expected. BUT selectedCategory has a child table 'SubCategory' which does not get loaded even though there is the include there. It is not loaded until I do this: selectedCategory.SubCategory.Load(); Why do I have to call load explicitly in order to load the child table?

  • Fibonacci Function Question

    - by DMan
    I was calculating the Fibonacci sequence, and stumbled across this code, which I saw a lot: int Fibonacci (int x) { if (x<=1) { return 1; } return Fibonacci (x-1)+Fibonacci (x-2); } What I don't understand is how it works, especially the return part at the end: Does it call the Fibonacci function again? Could someone step me through this function?

  • Horizontal Scrollview inside ListView item?

    - by lanks
    I have a ListView item layout that is using a HorizontalScrollView in the center. I have used the android attribute "android:descendantFocusability="blocksDescendants"" on my parent LinearLayout so that the ListView items are still selectable. The problem I am having is that when clicking the part of the ListView item which is the HorizontalScrollView, the ListView item click event is not called. How can I get the click event of the HorizontalScrollView to call the ListView list item click event?

  • jquery binding multiple events, and pass data

    - by mkoryak
    I know we can have this in 1.4: $("a").bind({ click : clickFn, mouseover: mouseFn }); and that is nice and i would like to use it, but it seems like there is no way to pass extra data to events bound this way, it needs to be done the 'old way': $("a").bind("click", {"some":"data"}, clickFn); Question: how can i pass the extra data to my event call backs and bind multiple events in a single bind at the same time?
