java - How to get bean property value from its getter method? -


i have json string contains custom object details follow.

{     "bankapp.bean.account.customerdetails": {         "setemail": "value",         "setcity": "value",         "setaddress": "value",         "setbesttime": "value",         "getbesttime": "value",         "setphone": "value",         "getpassword": "value",         "getcustomerid": "value",         "setlastname": "value",         "getemail": "value",         "getlastname": "value",         "setfirstname": "value",         "setcustomerid": "value",         "getphone": "value",         "setpassword": "value",         "getfirstname": "value",         "getcity": "value",         "getaddress": "value"     } }

i want properties of class using getter methods. here code snippet tried failed.

    string jsonstring = "{\"bankapp.bean.account.customerdetails\":{\"setemail\":\"value\",\"setcity\":\"value\",\"setaddress\":\"value\",\"setbesttime\":\"value\",\"getbesttime\":\"value\",\"setphone\":\"value\",\"getpassword\":\"value\",\"getcustomerid\":\"value\",\"setlastname\":\"value\",\"getemail\":\"value\",\"getlastname\":\"value\",\"setfirstname\":\"value\",\"setcustomerid\":\"value\",\"getphone\":\"value\",\"setpassword\":\"value\",\"getfirstname\":\"value\",\"getcity\":\"value\",\"getaddress\":\"value\"}}"; jsonobject jobject = new jsonobject(jsonstring); iterator = jobject.keys(); while(i.hasnext()) {     string currentkey = string.valueof(i.next());     object currentvalue = jobject.get(currentkey);      if(currentvalue instanceof string) {         system.out.println("primitive object");     }     else if(currentvalue instanceof jsonobject) {         //system.out.println("json object");         string key = getkeyname(jsonstring);         object jsonobject = jobject.get(key);         list<string> llist = breakthejson(jsonobject.tostring());         //list<string> allproperties = new arraylist<string>();          iterator<string> iterator = llist.iterator();         while (iterator.hasnext()) {                                     string val = iterator.next();                 if(val.startswith("get") || val.startswith("is")){                      system.out.println(val);                  }          }      }     else if(currentvalue instanceof jsonarray) {         system.out.println("custom object");       } }

so here in while loop got values like. 

getbesttime getpassword getcustomerid getemail getlastname getphone getcity getfirstname getaddress

now want value besttime , password etc. bean properties.

note : cant use java reflection because dont have class in classpath. getters want properties. please me.

you can simple gson

jsonobject json = new jsonobject(your_string); //get customerdetailsobject jsonobject jsonobject = json.getjsonobject("bankapp.bean.account.customerdetails");

pase gson

gson gson = new gson(); type typeof = new typetoken   <map<string, string>>(){}.gettype(); map<string,string> map = gson.fromjson(jsonobject.tostring(), typeof);   set<string> keys = map.keyset();     stringbuilder stringbuilder = new stringbuilder();         (string key : keys) {          stringbuilder.append(key).append(",");         }  string str = stringbuilder.tostring(); str = str.replaceall("get", "").replaceall("set", "");  // remove duplicate linkedhashset<string> list = new linkedhashset<string>(arrays.aslist(str.split(","))); (string property : list) {     string lowerchar = character.tostring(property.charat(0)).tolowercase();     system.out.println(lowerchar + property.substring(1, property.length()));     }

your properties 

email city address besttime phone password customerid lastname firstname

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...

python 3.x - Mapping specific letters onto a list of words -

can please suggest approach write piece of codes automatically maps letter in letter_str onto dic_key (a dict key string type contains dashes match length of words in word_lst)? so, mapping occurs if letter appears in every words in list @ same position no matter how many words in list. if no letter appears @ position words in word list new_dic_key '----'. please see examples below thanks word_lst = ['ague', 'bute', 'byre', 'came', 'case', 'doze'] dic_key = '----' letters_str ='abcdefghijklmnopqrstuvwxyz' new_dic_key = '---e' if word_list = ['bute', 'byre'] new_dic_key = 'b--e' or word_list = ['drek', 'drew', 'dyes'] new_dic_key = 'd-e-' if words in word_list of same length code give want: word_list = ['drek', 'drew', 'dyes'] cols = [] in range(len(word_list[0])): cols.append([]) word in ...
