Consider the following Java classes: class Foo { private Bar bar; public void foo() { bar.baz(); } } As can be seen, the class Foo needs to call the method baz on an instance of another class Bar for its method foo to work successfully. Bar is said to be a dependency for Foo sin...

The same examples as shown above with XML configuration can be re-written with Java configuration as follows. Constructor injection @Configuration class AppConfig { @Bean public Bar bar() { return new Bar(); } @Bean public Foo foo() { return new Foo(bar()); } } Property in...

Dependencies can be autowired when using the component scan feature of the Spring framework. For autowiring to work, the following XML configuration must be made: <context:annotation-config/> <context:component-scan base-package="[base package]"/> where, base-package is th...

Constructor injection through Java configuration can also utilize autowiring, such as: @Configuration class AppConfig { @Bean public Bar bar() { return new Bar(); } @Bean public Foo foo(Bar bar) { return new Foo(bar); } }

Objective-C Import the following to your ViewController #import <CoreImage/CoreImage.h> #import <CoreImage/CoreImage.h> #import <QuartzCore/QuartzCore.h> Call the function [self faceDetector]; Function definition: -(void)faceDetector { // Load the picture for face...

For Microfocus, it uses the "SleepEx" API. As an example; environment division. special-names. call-convention 74 is winAPI. : : 01 wSleep-time pic 9(8) comp-5. 01 wSleep-ok pic 9(8) comp-5. ...

Private Sub Get_Last_Used_Row_Index() Dim wS As Worksheet Set wS = ThisWorkbook.Sheets("Sheet1") Debug.Print LastRow_1(wS) Debug.Print LastRow_0(wS) End Sub You can choose between 2 options, regarding if you want to know if there is no data in the worksheet :...

Advanced functions behave the in the same way as cmdlets. The PowerShell ISE includes two skeletons of advanced functions. Access these via the menu, edit, code snippets, or by Ctrl+J. (As of PS 3.0, later versions may differ) Key things that advanced functions include are, built-in, customiz...

In this example, we will look at a method for returning the last non-empty column in a row. This method will work regardless of empty regions within the data set. However caution should be used if merged cells are involved, as the End method will be "stopped" against a merged region, ret...

First of all, Merged Cells are there only to improve the look of your sheets. So it is literally the last thing that you should do, once your sheet and workbook are totally functional! Where is the data in a Merged Range? When you merge a Range, you'll only display one block. The data will be ...

Pigeonhole Sort is a sorting algorithm that is suitable for sorting lists of elements where the number of elements (n) and the number of possible key values (N) are approximately the same. It requires O(n + Range) time where n is number of elements in input array and ‘Range’ is number of possible va...

Radix Sort is lower bound comparison based algorithm. It is a non-comparative integer sorting algorithm that sorts data with integer keys by grouping keys by individual digits which share some significant position and value. Radix sort is a linear time sorting algorithm that sort in O(n+k) time whe...

One easy algorithm to implement as a recursive function is factorial. ;;Compute the factorial for any n >= 0. Precondition: n >= 0, n is an integer. (defun factorial (n) (cond ((= n 0) 1) ;; Special case, 0! = 1 ((= n 1) 1) ;; Base case, 1! = 1 (t ...

If you're creating an image, decoding an image, or resizing an image to fit the large notification image area, you can get the correct pixel dimensions like so: Resources resources = context.getResources(); int width = resources.getDimensionPixelSize(android.R.dimen.notification_large_icon_width)...

DBCC commands can show information about database objects. DBCC PROCCACHE Displays information in a table format about the procedure cache. DBCC OUTPUTBUFFER ( session_id [ , request_id ]) Returns the current output buffer in hexadecimal and ASCII format for the specified session_id (and o...

To render your new component in a view, you cust call: @Html.Action("MemberLoginForm", "MemberLoginSurface")

Git config allows you to customize how git works. It is commonly used to set your name and email or favorite editor or how merges should be done. To see the current configuration. $ git config --list ... core.editor=vim credential.helper=osxkeychain ... To edit the config: $ git config &lt...

Inheritance is one of the main concepts in Object Oriented Programming (OOP). Using inheritance, we can model a problem properly and we can reduce the number of lines we have to write. Let's see inheritance using a popular example. Consider you have to model animal kingdom (Simplified animal kingdo...
