flags

问题 I am a beginner. I already checked the programming guidance dictionary. I am considering a two-lane road (eg, road 1, road 2) model. And also I am considering a model in which the turtle specified by the specified patch((10 0) and (20 2)) stops for 10 ticks. However, I do not know how to write and specify the specific parameter for xcor and ycor for each road (Eg xcor and ycor on road 1, xcor and ycor on road 2). And also I do not know how to write and controol the parameter "speed" within

问题 For the sake of curiosity I'm trying to read the flag register and print it out in a nice way. I've tried reading it using gcc's asm keyword, but i can't get it to work. Any hints how to do it? I'm running a Intel Core 2 Duo and Mac OS X. The following code is what I have. I hoped it would tell me if an overflow happened: #include <stdio.h> int main (void){ int a=10, b=0, bold=0; printf("%d\n",b); while(1){ a++; __asm__ ("pushf\n\t" "movl 4(%%esp), %%eax\n\t" "movl %%eax , %0\n\t" :"=r"(b) :

问题 I have the following enum flags: [Flags] private enum MemoryProtection: uint { None = 0x000, NoAccess = 0x001, ReadOnly = 0x002, ReadWrite = 0x004, WriteCopy = 0x008, Execute = 0x010, ExecuteRead = 0x020, ExecuteReadWrite = 0x040, ExecuteWriteCopy = 0x080, Guard = 0x100, NoCache = 0x200, WriteCombine = 0x400, Readable = (ReadOnly | ReadWrite | ExecuteRead | ExecuteReadWrite), Writable = (ReadWrite | WriteCopy | ExecuteReadWrite | ExecuteWriteCopy) } Now i have an enum instance that I need to

问题 I have been writing Parcelable s to Parcel without any focus on flags field, which is a parameter in the method signature and it has worked fine but I have run into an implementation where I can no longer ignore them: public static <K extends Parcelable, V extends Parcelable> void write(Parcel dest, Map<K, V> map, int flags) { if (map == null) { dest.writeInt(-1); } else { Set<Map.Entry<K, V>> entrySet = map.entrySet(); dest.writeInt(entrySet.size()); for (Map.Entry<K, V> entry : entrySet) {

问题 My question refers directly to this question. The answer to that question shows how one can create a ViewGroup , embed it inside a WindowManager , and allow the WindowManager to catch MotionEvent s through onTouchEvent(MotionEvent event) . WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH is the flag that allows this this ViewGroup to receive MotionEvent s. However, according to documentation, this flag ...will not receive the full down/move/up gesture I want to know if there's a work

问题 I am trying to get into testing in Python using the doctest module. At the moment I do Write the tests for the functions. implement the functions code. If Tests pass, write more tests and more code. When the function is done move on to the next function to implement. So after 3 or 4 (independent) functions in the same module with many tests I get a huge output by doctest. And it is a little annoysing. Is there a way to tell doctest "don't test functions a() , b() and c() ", so that it runs

问题 I'm writng a small application in PHP + MySQL and have come to the point where there is an object that has a couple (8 so far but not expected to increase) of flags associated with it. The flags are pretty much unrelated although there are some combinations that would make no sense. The object represents a row in a DB (has some methods for saving/loading it too) so the question also applies to choosing a storage method. The question is - how to best represent them both in code and DB? I can

问题 I am asking this out of a curiosity. Basically my question is when you have a database which needs a row entry to have things which act like flags, what is the best practice? A good example of this would be the badges on stack overflow, or the operating system field in bugzilla. Any subset of the flags may be set for a given entry. Usually, I do c and c++ work, so my gut reaction is to use an unsigned integer field as a set of bits which can be flipped... But i know that isn't a good solution

问题 I find out that we can use cool flags that scroll both toolbar and even content by using layout_scrollFlags . In my case, I have a layout like this: <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent"> <android.support.design.widget.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap

问题 Sometime I'd like to spawn a child process with the same optimization flags used to start the parent. I can use something like: optimize = not __debug__ But this way I match both -O and -OO flags. Is there some python internal status that contains that info? 回答1: After some digging in the documentation I've found that the sys.flags struct sequence (http://docs.python.org/dev/library/sys#sys.flags) that has an optimize attribute containing the information I was searching for. python -c "import
