Scala regex format match result -


मैंने एक फ़ंक्शन लिखा 

  def extract मोबाइल नंबर: सूची [स्ट्रिंग] = {pattern.findAllIn (एस) .toList}   
 जहां  
  वैल पैटर्न = "[0- 9] {9}"। R   <पी> जो सूची देता है [इंट] 
 उदा इनपुट "मैडम कृपया मुझे 111111111 पर कॉल करें और 223322 पर लैंडलाइन" आउटपुट: लिस्ट [111111111]  
 चूंकि मैं सीख रहा हूँ, मैं यह समझ नहीं पा रहा हूं कि मैं कैसे पैटर्न का उपयोग कर सकता हूं। ReplaceAllIn (s, matcher) लौटने के लिए "मैडम कृपया मुझे  111-111-111  और 223322 पर लैंडलाइन पर कॉल करें।"   
 
 <पूर्व>  val input =" मैडम कृपया मुझे 111111111 पर कॉल करें और 223322 पर लैंडलाइन ":: नील वेल फोन नंबर =" (। +) ([0- 9] {3}) ([0- 9] {3}) ([0- 9] {3}) (। +) ".आर मूल्य संसाधित = input.map {केस फोन नंबर (उपसर्ग, पी 1, पी 2, पी 3, प्रत्यय) = & gt; S "$ उपसर्ग $ p1- $ p2- $ p3 $ प्रत्यय" केस s = & gt; S} प्रसंस्कृत। फोरेक (println)   
 आउटपुट:  
  मैडम कृपया मुझे 111-111-111 पर कॉल करें और 223322 पर लैंडलाइन कॉल करें  < / प्री>

python - how we can use ajax() in views.py in django? -

I have a little code here. Could you please tell me what this code really does? please. Here in the AJAX call: $ .ajax ({url: "{% url} upload_document '%}", type: "POST", data : {Csrfmiddletoken: document.getElementsByName ('csrfmiddletoken') [0] Price, Title: document.getElementById ('title'). Value, // document: document: document.getElementById ('document'),}, datatype: "Jason", success: function (feedback) {if (feedback == "true") {// success} other {// attachment errors}}}); How AJAX works in the Django and how we can see the AJAX request. Here is the idea of ​​my thoughts def upload_document (requested): Print request. POTT print request FILES if request.is_ajax (): If request.method == 'POST': form = UploadForm (request.POST, request.FILES, user = request.user) if form.is_valid (): Form.save () return HTTPPCS (SimpleJason Dumps ('True'), Mime Type = 'App / Jason') Other:...

c - Performance of System() -

After the function in C, for the system (), it affects the hardware counters, so how do you order that The example displayed for the example you are trying to view lets the IM use the display API (PAPI) and the program is a precompiled matrix multiplication application. PAPI_start_counters (); System ("./matmul"); PAPI_read_counters (); // Print the values ​​PAPI_stop_counters (); I'm clearly missing a bit, but I'm trying to figure out what it is possible to say, counter receiving a program im running Is through use. With my tests I will get wild numbers like below, they are clearly wrong, just want to find out why total bicycle =========== 140733358872510 instructions complete =========== 4203968 Floating Point Instructions =========== Floating Point Operations =========== 4,196,867 Weight ======= ==== 140733358872804 store ======= ==== 4204037 branches taken =========== 15774436 System () Normally it is a very slow function, on Linux, it is ...

c++ - How to define methods in a base class that only work in derived classes? -

The title is slightly ambiguous, so I will say an example of what I want to achieve: Class ValuePtr {Public: Operator Canned void * () {return glm :: value_ptr (* this); // value ptr will not work on this class // (works only on glm type)}}; Square mat4x4: public glm :: mat4x4, public valuePtr {// ... but will work here}; Square Vec3: Public glm :: vec3, Public ValuePtr {// ... and here. } Is such a thing possible? glm :: value_ptr works only on glm type like glm :: mat4x4 , glm: : Vec3 , etc. The above seen method works if I implement it directly into derivative classes, but they should all be defined as operator construct * zero * in the same way. I should behave like a special behavior: define it in the general base class, whereas definition only works in derived classes. Thank you for the answer, I use this solution: template & lt; Class T & gt; Class ValuePtr: Public T {Public: Operator Constant * () {return glm :: value_ptr (* this); }}; Class ...
