Understanding Access Modifiers in X++ Programming Language: A Complete Guide

Here are the four access modifiers in X++ programming language:
- Public: A public member is accessible to all classes, including classes in other assemblies. This is the default access modifier for members.
- Protected: A protected member is accessible to classes in the same assembly and to subclasses of the class where it is declared.
- Private: A private member is only accessible to methods in the class where it is declared.
- Internal: An internal member is accessible to all classes in the same assembly. This is a new access modifier in X++ 10.
The following table summarizes the visibility of members with different access modifiers:
| Access modifier | Visibility |
|---|---|
| Public | Visible to all classes |
| Protected | Visible to classes in the same assembly and subclasses |
| Private | Visible only to methods in the class |
| Internal | Visible to all classes in the same assembly |
Access modifiers are used to control the visibility of members in a class. This helps to encapsulate the data and functionality of the class, and to protect it from unauthorized access.
Here are some examples of how access modifiers can be used in X++:
- A public method can be called from any class, anywhere in the program.
- A protected method can only be called from classes in the same assembly and from subclasses of the class where it is declared.
- A private method can only be called from methods in the class where it is declared.
- An internal method can only be called from classes in the same assembly.
