Class Layout

In C++, as in many other languages, classes are the key feature that supports data abstraction. A C++ class is essentially a C structure, but with added capabilities that support object-oriented programming as well as better type safety, resource management, and usability.

Although some of these added capabilities require additional storage allocation or run-time support, most do not. Thus, the storage layout for a C++ class can be as simple as the layout for a C structure. Unfortunately, too many programmers imagine that classes incur space and speed penalties that simply aren’t there.

This session offers a practical look “under the hood” to see how compilers typically implement the storage layout and member access for C++ classes. It also explains how compilers typically implement member function calls. You’ll come away with a better sense of what using classes actually costs in speed and space. You’ll gain insights that will help you with a variety of programming tasks, including debugging, performance tuning, and working with objects that have rigid layout requirements.

How to Find All the Classes of a Package in Java

In this article let’s take a look at how to find all classes of a package in Java

To find all classes of a package in Java we can use the ClassHunter of Burningwave Core library. So we start by adding the following dependency to our pom.xml:

XML

1

<dependency>2
    <groupId>org.burningwave</groupId>3
    <artifactId>core</artifactId>4
    <version>8.4.0</version>5
</dependency>

The next steps are the following:

  • retrieving the ClassHunter through the ComponentContainer
  • defining a regular expression that we must pass to the **ClassCriteria **object that will be injected into the **SearchConfig **object
  • calling the **loadInCache **method that loads in the cache all loadable classes of the indicated paths, then applies the criteria filter and then returns the **SearchResult **object which contains the classes that match the criteria

Creating an Immutable Class in Java

In this article, we’ll define the typical steps for creating an immutable class in Java and then implement it.

Steps to create Immutable class in java

  1. Make your class final, so that no other classes can extend it.
  2. Make all fields private so that direct access is not allowed.
  3. Don’t provide “setter” methods — methods that modify fields or objects referred to by fields.
  4. Special attention when having mutable instance variables
  5. Inside the constructor, make sure to use a clone copy of the passed argument and never set your mutable field to the real instance passed through the constructor.
  6. Make sure to always return a clone copy of the field and never return the real object instance.
