• hibernate search and projection - different fields on different objects

  - by Odelya

  Hi! I have the following code: Criteria crit = sess.createCriteria(Product.class); ProjectionList proList = Projections.projectionList(); proList.add(Projections.property("name")); proList.add(Projections.property("price")); crit.setProjection(proList); But I also have User.class and I would like the name to be restricted on User.class and price from Product class. How can I restrict different columns on different objects in Hibernate Search?

• Access static Method in GDB

  - by Besi

  I recently discovered the GDB in Xcode which makes up for some functionality which IMHO seems to be lacking in Xcode. So I can do the following in GDB: (gdb) po [LoginManager sharedSession].loginToken 20D52FE9-3573-437E-9A65-846572B63726 However, I have another Service class, which is currently not loaded so I get the following error: (gdb) po [SessionService displaySessionInfoForToken:@"XXX"] No symbol "SessionService" in current context. I don't understand why the LoginManager can be loaded but not the SessionService.

• does passing __m128i objects by reference to inline function cause these objects to be moved to stac

  - by ~buratinas

  Hello, I'm writing transpose function for 8x16bit vectors with SSE2 intrinsics. Since there are 8 arguments for that function (a matrix of 8x8x16bit size), I can't do anything but pass them by reference. Will that be optimized by the compiler (I mean, will these __m128i objects be passed in registers instead of stack)? Code snippet: inline void transpose (__m128i &a0, __m128i &a1, __m128i &a2, __m128i &a3, __m128i &a4, __m128i &a5, __m128i &a6, __m128i &a7) { .... }

• How to avoid the linebreak inside a word (Static Layout

  - by Addev

  I'm trying to make a text as big as I can making it fit a Rect. basically I use a StaticLayout for pre-calculate the text size and make it fit the Rect's height: // Since the width is fixed for the StaticLayout it should only fit the height while (currentHeight>Rect.getHeight()){ size-=2; } textPaint.setTextSize(size); The problem is that if the Rect is very high, the exit condition is reached but breaking the words (see the capture). Is there a way for avoid this? Goal: Actual: Current code: textSize=MAX_TEXT_SIZE do { if (textSize < mMinTextSize) { Log.i(TAG, "Min reached"); textSize = mMinTextSize; textPaint.setTextSize(textSize); fits = true; } else { textPaint.setTextSize(textSize); StaticLayout layout = new StaticLayout(text, textPaint, targetWidth, Alignment.ALIGN_NORMAL, 1.0, 0, true); layout.draw(canvas); float heightRatio= (float) layout.getHeight() / (float) targetHeight; boolean fitsHeight = heightRatio<= 1f; if (fitsHeight) { fits = true; } else { textSize -= 2; } } Log.i(TAG, "textSize=" + textSize + " fits=" + fits); } while (!fits); thanks

• C++ How fast is passing around objects?

  - by wndsr

  Assuming we are running a compiled C++ binary: Is passing around an int (e.g. function to function, or writing it into variables) slower than passing around structs/class objects like the following? class myClass { int a; int b; char c; vector d; string e; }

• Best way to use the same HTML on static web-pages

  - by John

  If you use dynamic pages like JSP or asp.net, you can have your page template included, and then content added. But what if you have no server-side component and all pages are just HTML/JS? You can of course create a template then copy it for each page, but then if you want to change something you risk having to modify every page, even if you put most styling in CSS properly. Are there any non-awful ways to do this? I could see that an iframe could be used to load the content into the central page but that sounds nasty. Does HTML provide any way to include a base file and add to it?

• API for configuring static IP addresses in an android application

  - by awoodland

  Is it possible to set the IP address of an interface in Android within an application? I can query the available interfaces and their current addresses using java.net.NetworkInterface, but this doesn't provide a facility to change these. Did I just miss something somewhere or is it not allowed? I was hoping to be able to make my application either change or add an alias to one or more of the existing interfaces at runtime on an "off the shelf" device. (2.1/2.2). Ideally I'd like to do this for both IPv4 and v6 addresses.

• How to find dynamically loaded modules (the static ones) programatically in windows

  - by Ryan Rohrer

  I'm trying to port the unix utility ldd to windows, because dependency walker and cygcheck don't quite give me the usage I'm looking for. (also for the learning experience) Ive been looking all over MSDN, for a windows API that lists dll dependencies of an executable, or even the storage format in the complied exe (just to filter it out), but I've been unable to find anything. If anyone knows what API call windows uses for listing modules to load, or what patterns I can search for in an executable to find modules to load, please help me out :) thanks! -note: I'm not looking to profile for dynamic modules, just list the ones that are required at runtime

• Sorting Custom Objects with Parameter in VB.Net/C#

  Let's say I have a custom object of Foo Is there anyway I can sort through a list of these objects, like list<of foo>.sort() and also be able to sort this list with a passable parameter. which will influence the sort? list<of foo>.sort(pValue) I'm guessing I'll need to define two separate sorts, but I am not sure. Thanks!

• C# Object Array CopyTo links both arrays' values?

  - by Dutchie432

  Okay, I have what I think is a simple question.. or just a case of me being a C# beginner. I have an array of custom objects (clsScriptItem) that I am populating from a database. Once the items are loaded, I want to back them up to "backup" array so I can revert the information back after changing the main array. However, when I use CopyTo to copy the array and then alter the original array, the backup array is also being altered... I though CopyTo merely copied values + structure from one array to another. private void backupItems() { lastSavedItems = new clsScriptItem[items.Length]; items.CopyTo(lastSavedItems, 0); //items[0].nexts[0] is 2 //lastSavedItems[0].nexts[0] is 2 items[0].nexts[0] = "-1"; //items[0].nexts[0] is -1 //lastSavedItems[0].nexts[0] is also -1 } How do I backup this data without having the two arrays be 'linked'??

• Android Static Variable Scope and Lifetime

  - by Edison

  I have an application that has a Service uses a ArrayList to store in the background for a very long time, the variable is initialized when the service started. The service is in the background and there will be frequent access to the variable (that's why i don't want to use file management or settings since it will be very expensive for a file I/O for the sake of battery life). The variable will likely to be ~1MB-2MB over its life tie. Is it safe to say that it will never be nulled by GC or the system or is there any way to prevent it? Thanks.

• Programmatically find maximum static array size in C++

  - by GuyGreer

  I am curious whether it is possible to determine the maximum size that an array can have in C++. #include <iostream> using namespace std; #define MAX 2000000 int main() { long array[MAX]; cout << "Message" << endl; return 0; } This compiles just fine, but then segfaults as soon as I run it (even though array isn't actually referenced). I know it's the array size too because if I change it to 1000000 it runs just fine. So, is there some define somewhere or some way of having #define MAX MAX_ALLOWED_ARRAY_SIZE_FOR_MY_MACHINE_DEFINED_SOMEWHERE_FOR_ME? I don't actually need this for anything, this question is for curiosity's sake.

• Are PHP5 objects passed by reference?

  - by morpheous

  I cant seem to get any consistent info on this. Different sources appear to say different things and trhe venerable php.net iteslf (appears) not to explicitly state this - although I must admit, I only had a quick look. In cases where I am passing around 'heavy' objects, I need to pass by reference, but I dont want to keep typing: function foo(TypeName& $obj) if I can get away with simply, function foo(TypeName $obj) So what does the standard say?

• C++ static array leading to memory leak?

  - by MDonovin

  Lets say I have something like... void foo() { char c[100]; printf("this function does nothing useful"); } When foo is called, it creates the array on the stack, and when it goes out of scope, is the memory deallocated automatically? Or is c destroyed, but the memory remains allocated, with no way to access it/get it back except restarting the computer?

• Access specifier's and classes and objects?

  - by TimothyTech

  Alright, im trying to understand this, so a class is simply creating a template for an object. class Bow { int arrows; }; and an object is simply creating a specific item using the class template. Bow::Bow(arrows) { arrows = 20; } also another question, public specifiers are used to make data members avaible in objects and private specifiers are used to make data memebers only avaialble inside the class?
