OCaml is a general-purpose programming language that provides us object-oriented features, OCaml is open source and free. It comes up with some more features such as pattern matching, exception handling, automatic garbage collection, and many more which we will see in detail in the coming sectio...
Racket has a specialized data structure called a syntax object that is the medium of exchange among macros. Unlike a string, which can only contain raw code, a Racket syntax object packages the code in a way that preserves its hierachical structure, plus metadata li...
In Python, we will get this type of error during coding.The error AttributeError: ‘NoneType’ object has no attribute ‘something’ occurs in Python when we try to access an attribute or method (something) on an object that is None. In this blog, we will learn multiple cases where ...
Why Do We Need NETCONF? Network automation is one of the key requirements for networks in the cloud era, including fast and on-demand service provisioning and automatic O&M. However, this requirement cannot be met by the conventional network management methods: command-line interface (CLI) and...
and receive an appropriate starting template based on those decisions. I know what detractors are going to say, “One solution can’t apply to every problem” (haters gonna hate). And they might be right. But we can do our best to create an approximate solution, and I think Init comes ...
As of MATLAB 6.1 (R12.1), the function NUMEL was added to enhance the power of MATLAB object oriented programming. In short, the function allows you to index into objects with an arbitrary length vector, and return an arbitrary number of output arguments. ...
Why do we need a constructor as a class member? We need a constructor as a class member in Javato initialize the instance variables which are declared. This initialization can be done in two ways: => Direct initialization using a Default Constructor, in which direct values are assigned to ...
Because Xojo has the simplicity of VB6 but is totally object-oriented and allows me to compile independently for Windows or Linux and for Robotics applications it is perfect. - C. Kanah I've used many languages over the years, but the Xojo programming language has made me more productive tha...
The advent of object-oriented programming led to the development of object-oriented testing, a more complex testing methodology than traditional functional testing. Similarly, the rise of web-based applications has led to web and web application testing development. Testing tools and techniques will ev...
Namespaces are one honking great idea -- let's do more of those! This code has import this on input line 1. The output from running import this is to print the Zen of Python onto the console. We’ll return to several of the stanzas in this poem later on in the article. In many ...
