问题 This question already has answers here : Subclassing Javascript Arrays. TypeError: Array.prototype.toString is not generic (6 answers) Closed 3 years ago . I'm trying to create an Object/Class in Javascript that behaves like an Array but with some added functionalities. I've achieved this with these simple lines: var Newclass = Array Newclass.prototype.get_by_id = function(){} However, I'm trying to perform some actions just when I call this new class, so elements I'm adding to this are

Changing object state in const method

阅读更多关于 Changing object state in const method

问题 I have class that resembles this: class A{ std::string tmp; public: const std::string &doSomething() const{ tmp = "something"; return tmp; } }; It is very important the method doSomething() to be const and to return reference instead of the string itself. Only way I see is to do it with dynamic allocation, e.g. something like: class A{ MyClass *tmp = new MyClass(); public: const MyClass &doSomething() const{ *tmp = "something"; return *tmp; } }; tmp variable "placeholder" is used ONLY inside

问题 I built and ran a JAR on machineA as follows: java -cp /foo/lib/dep1.jar:/foo/lib/dep2.jar:/foo/export/myjar.jar foo.bar.baz.MyMainClass ... So myjar.jar is the JAR I built and the other two its dependencies. Ran without any issues. I then wanted to do the same on machineB so I copied the 3 JAR files there, then tried: /non/default/install/java -cp /bar/dep1.jar:/bar/dep2.jar:/bar/myjar.jar foo.bar.baz.MyMainClass ... and got Error: Could not find or load main class . (NOTE: /non/default

问题 I'm working with an Arduino UNO in my first attempt to use the OO in Wiring. I just have a question which I need help with; I'm using a class for a DHT22 sensor from freetronics, found here http://www.freetronics.com/products/humidity-and-temperature-sensor-module. Say I have a class i made called Sensor, where DHT is the library for the freetronics sensor, and DHT dht(5, DHT22) Initialises the sensor on pin 5 (which could be any digital pin): #include "arduino.h" #include <DHT.h> DHT dht(1,
