java - How to limit generic class parameter to certain classes -


मेरे सामान्य वर्ग में मुझे टाइप पैरामीटर को Integer OR स्ट्रिंग क्या इसको हासिल करने के लिए कोई रास्ता है? प्रकार को सीमित करने के लिए मैं टी कुछ क्लास का उपयोग नहीं कर सकता , क्योंकि सामान्य पैरेंट केवल ऑब्जेक्ट है ...

अपडेट 

  सार्वजनिक सार वर्ग MyClass & lt; T & gt; {निजी टी मूल्य; सार्वजनिक टी getValue () {वापसी मूल्य; }}   
 मुझे  मान  प्रकार को एक  स्ट्रिंग  या एक  पूर्णांक  होना चाहिए और I इसे प्राप्त करने के लिए एक ही विधि का उपयोग करने की आवश्यकता है ( getIntValue ()  +  getStringValue () )  
 मदद नहीं लगता है ... < / P>  
 
 
 अगर मैं आप था, तो मैं  अधिभार  दो विधियों:  
  सार्वजनिक के साथ शून्य (पूर्णांक परम) {..} सार्वजनिक शून्य के साथ स्ट्रिंग (स्ट्रिंग परम) {..}   
 ध्यान दें कि  टी स्ट्रिंग को बढ़ाता है , क्योंकि  दोनों   स्ट्रिंग  और  पूर्णांक  है  अंतिम  और subclassed नहीं किया जा सकता है ।

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 ...

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:...

python - Sequence Pattern recognition with Pybrain -

Image
I am constantly trying to use recurrent neural networks to classify a series of data. To be more specific, I have a sequence of sensor reading (which is continuous over time), I have to learn an algorithm which can detect the state related to this pattern, given the readings change. Example: Time step_1: 1.4 Time step_2: 1 Time step_3: 0.8 State = New Sequence: Time Phase 1: 0.4 Time Phase 2: 0.3 Time Phase 3: 0.1 State = Sitting I actually have 12 censors, I'm just showing a sequence of numbers for convenience. (Numbers are not real, I'm just trying to fulfill this idea)! I am trying to make my network with PyBrain RNN, however, I can not get a Data Set Container that can detect it, like information I tried to use sequential data But after some testing I came to know that this number is the next element in the sequence of numbers. Here's how I prepare my dataset: self.alldata = SequentialDataSet (ds.num_features, 1) # Now add samples to the dat...
