问题 im making a custom reports for woocommerce im trying to add a report for all delivered orders here is what im doing $orders = wc_get_orders( array('numberposts' => -1) ); foreach( $orders as $order ){ if ( $order->get_status() === completed){ $order_data = $order->get_data(); // The Order data $items = $order->get_items(); foreach ( $items as $item ) { $product_name = $item->get_name(); $product_id = $item->get_product_id(); } $orders_completed .= '<tr><td>' . $order->get_order_number() . '<

问题 I already have a working, but in my oppinion not beautiful solution for a part of a long script. My script uses several similar methods, that differ too much to combine. However I came to a point where I want to call one of those methods depending on a given variable. The names of the methods are build up like this: def read_A(): #doing sth def read_B(): #doing sth else def read_C(): etc. Now I would like to call those methods in a pythonic way, when the letter ( 'A' , 'B' , 'C' , ...) is

问题 I was just introduced to recursion and I was given the following lines of code: public class RecursionThree { public void run(int x ) { if(x<5) run(x+1); out.println(x); } public static void main(String args[] ) { RecursionThree test = new RecursionThree (); test.run(1); } } and the output is supposed to be: 5 4 3 2 1. I get why it would print 5 (because 5<5 would equal false and it would print x, which is 5). However, I do not understand why it prints 4 3 2 1 too. Thanks for your help 回答1:

问题 If I run the following program: class Runit{ public static void main(String[] argsWut) throws Exception { String arg = "what?"; Class[] parameters = { new Object().getClass() }; Object[] args = { arg }; System.out.println("".getClass().getMethod("equals",parameters).invoke("what?",args)); } }; I get the following on the command line: true On the other hand, if I modify the parameters line a little: class Runit{ public static void main(String[] argsWut) throws Exception { String arg = "what?";

问题 I want to ask you how to declare a variable that can be used by every method? I tried making the method's access type public but that didn't let me used its variable across other methods Moreover, I basically want to accumulate that variable with different values across different methods that's why I am asking this. NOTE: I want to avoid making any static classes. EDIT: For example, I did public decimal MiscMethod() { decimal value1 += 23m; } public decimal AutoMethod() { decimal value 1 +=

问题 Producer methods are very useful for creating instances programmatically and publishing them in a context. The problem is that all properties of an instance created by new and returned by a producer method are not injected by CDI. In the Weld documentation I've read that this is an intentional behaviour, but in many cases injection in those beans would be very useful. Is there a workaround to enable injection into such beans? 回答1: First, I have to ask why you are using Producers for beans

问题 I have my student S3 class # a constructor function for the "student" class student <- function(n,a,g) { # we can add our own integrity checks if(g>4 || g<0) stop("GPA must be between 0 and 4") value <- list(name = n, age = a, GPA = g) # class can be set using class() or attr() function attr(value, "class") <- "student" value } I want to define the class groupofstudents : stud1 <- student("name1", 20, 2.5) stud2 <- student("name2", 21, 3.5) groupofstudents <- function(firststud = stud1,

问题 I' trying to make something like this: public interface ICar { public void Update(/*something here*/); } Then two classes: public class Peugeot : ICar { public void Update(Peugeot car) { } } public class Volvo : ICar { public void Update(Volvo car) { } } How can I achieve this? 回答1: You could make ICar generic: public interface ICar<T> where T : ICar<T> { public void Update<T>(T car); } And then implement the Update methods accordingly: public class Peugeot : ICar<Peugeot> { public void

问题 PROBLEM I am using Python3 and Kivy2. Regardless I would like a popup to automatically start a time consuming method in the background DESCRIPTION In the script call for the popup when a condition is met. if self.header == "loadbag": messageTitle = "machine status" messageLabel = "work in progress" self.popup(messageTitle, messageLabel) The popup method structure is: def popup(self, boxTitle, boxLabel): # popup for showing the activity self.MessageButtonCancel = "ANNULLA" self.MessageBoxTitle
