parameter-passing

I declared a variable outside the function like this: var s: Int = 0 passed it such as this: def function(s: Int): Boolean={ s += 1 return true } but the error lines wont go away under the "s +=" for the life of me. I tried everything. I am new to Scala btw. First of all, I will repeat my words of caution: solution below is both obscure and inefficient , if it possible try to stick with val ues. implicit class MutableInt(var value: Int) { def inc() = { value+=1 } } def function(s: MutableInt): Boolean={ s.inc() // parentheses here to denote that method has side effects return true } And here

I am redirecting from one action (executeProcess) to another (executeIndex). I want to be able to pass a parameter/variable along, without using GET (e.g. $this->redirect('index', array('example'=>'true')) ) Is there a way I can directly pass parameters without having it directly displayed in the URL? (e.g. POST). thanks. Why dont you use sessions to store values before redirecting, and then getting them on the other action after you redirected? like: class ActionClass1 extendes sfActions { public function executeAction1(sfWebRequest $request) { [..]//Do Some stuff $this->getUser()-

I'm using Jenkins for testing/build purposes, so I created a MultiJob project with this configuration: Test Job Build Job Install Job The MultiJob is launched from the Master Jenkins, but other jobs are launched from other Nodes. The Build Job executes a shell script which creates the BUILD_ID. Now, I want the BUILD_ID to be passed as parameter to the Install Job. How can I do that? My only choice is to use a property file? Thanks a lot To use the suggestion i am going to describe, you will need Parameterized Trigger plugin. One way to pass custom parameter to a downstream job is by storing

Being relatively new to Python in this question I may use some incorrect terminology and will display misunderstanding - which I why I am here. I am studying Python functions and am trying to ensure I understand how variables are passed and returned. I have written this trivial function to sort items in a list def func_sort_list(NN): for w in NN: print (w, type(w)) NN.sort() print (NN) return (w) I have assigned values to a list unsort_letters=['q','w','e','r','t','y'] Then I envoke the function func_sort_list(unsort_letters) and get the result q <class 'str'> w <class 'str'> e <class 'str'> r

If I have func returnIntAndString() (i int, s string) {...} And I have: func doSomething(i int, s string) {...} Then I can do the following successfully: doSomething(returnIntAndString()) However, let's say I want to add another argument to doSomething like: func doSomething(msg string, i int, s string) {...} Go complains when compiling if I call it like: doSomething("message", returnIntAndString()) With: main.go:45: multiple-value returnIntAndString() in single-value context main.go:45: not enough arguments in call to doSomething() Is there a way to do this or should I just give up and assign

So we've got a whole lot of Postgres SQL queries stored in files and used from PHP. The task is to replace PHP with Java. We want to reuse as much of the queries "as is" to keep the migration path short. I can't get the Array parameters to work. Here's a query example: update user_devices set some_date = now() where some_id in ( select distinct some_id from user_devices where user_id = any(:userIDs) and device_id = any(:deviceIDs) and exists (select 1 from users where user_id = any(:userIDs) and customer_id = :customerID) ); Note the "any" clauses, which cause the problem, because they expect

First of all, sorry for bringing a question that has been answered so many times, but I have tried most of the procedures mentioned and still can't get it working. I have an ASP.NET app (server-side), and I would like to visualize some results by using WebGL (JavaScript, client-side). I am able to create the canvas in aspx file and to draw a 3D object (a cube) by writing ALL the necessary JS code in a jscript file (As long as I know what I want to draw in advance, and writing all that in Jscript). However, my intention is to write a different object depending on my server-side code. When I
