Hey guys, I noticed that I rarely use properties, due to the fact that I rarely need to access my object's variables outside my class ;) So I usually do : NSMutableArray *myArray; // not a property ! My question is : even if i don't declare myArray as a property, does iphone make a retain anyway if I do myArray = arrayPassedToMe;...
The textbook examples of multiple unpacking assignment are something like: import numpy as NP M = NP.arange(5) a, b, c, d, e = M # so of course, a = 0, b = 1, etc. M = NP.arange(20).reshape(5, 4) # numpy 5x4 array a, b, c, d, e = M # here, a = M[0,:], b = M[1,:], etc. (ie, a single row of M is assigned each to a through e) (My Q ...
Hello, I have a Java array defined already e.g. float[] values = new float[3]; I would like to do something like this further on in the code: values = {0.1f, 0.2f, 0.3f}; But that gives me a compile error. Is there a nicer way to define multiple values at once, rather than doing this?: values[0] = 0.1f; values[1] = 0.2f; values[2...
Hi guys, I was wondering if i could assign values to a variable inside an IF statement. My code is as follows: <?php if ((count($newArray) = array("hello", "world")) == 0) { // do something } ?> So basically i want assign the array to the $newArray variable, then count newArray and check to see if it is an empty arra...
I have read the question here: http://stackoverflow.com/questions/2229389/is-it-problematic-to-assign-a-new-value-to-a-method-parameter. However it is not clear to me if doing something like: public void myMethod(Object obj) { doSomething(obj); obj = getNewObj(); } or: public void anotherMethod(Object obj) { obj = doSomet...
Greetings Stack Overflowers, A while back, I was working on a program that hashed values into a hashtable (I don't remember the specifics, and the specifics themselves are irrelevant to the question at hand). Anyway, I had the following code as part of a "recordInput" method. tempElement = new hashElement(someInt); while(in.hasNex...
Is this well defined? Streamreader ^reader = gcnew Streamreader("test.txt"); String ^line; while ((line = reader->ReadLine()) != nullptr && line != "") { //do stuff } I believe that I read somewhere that it is not guaranteed that the assignment is executed before the 2nd conditional. It may be that I'm wrong or that this just ap...
Is there a way to do a variable assignment inside a function call in python? Something like curr= [] curr.append(num = num/2) ...
I wonder if I can do assignment using TResult<in T, out TResult> I can retrieve the value of the property of a class instance with that delegate as below: class Program { class MyClass { public int MyProperty { get; set; } } static void Main(string[] args) { Func<MyClass, int> orderKeySelector = o =>...
Hi, I was studying some code I found on the web recently, and came across this php syntax: <?php $framecharset && $frame['charset'] = $framecharset; ?> Can someone explain what is going on in this line of code? What variable(s) are being assigned what value(s), and what is the purpose of the && operator, in that location of the state...
What is the difference in these two statements in python? var = foo.bar and var = [foo.bar] I think it is making var into a list containing foo.bar but I am unsure. Also if this is the behavior and foo.bar is already a list what do you get in each case? For example: if foo.bar = [1, 2] would I get this? var = foo.bar #[1, 2] a...
