ASNA.QSys.Runtime Interfaces
Estimated reading time: 4 minutes
Remarks
The ASNA.QSys.Runtime assembly contains a collection of interfaces that are used throughout the ASNA QSys system. These interfaces define a contract of operations, properties, and events that classes can implement, providing a way to achieve polymorphism and increase the flexibility and interoperability of the system.
These interfaces cover a wide range of functionalities, from defining date/time formats and separators, to identifying classes that participate in the ActivationGroup logic, to defining functionality for files that participate in the RPG cycle.
Here are some key points to remember when working with these interfaces:
- Polymorphism: By defining a common interface, different classes can implement the same interface in different ways. This allows you to write code that can work with objects of any class that implements a particular interface.
- Flexibility: Interfaces allow you to create systems that are flexible and easily extensible. You can add new classes that implement these interfaces without having to change the existing code that uses the interfaces.
- Interoperability: These interfaces provide a consistent way to interact with different parts of the ASNA QSys system, increasing the interoperability of your code.
Remember to refer to the individual interface documentation for specific details about each interface’s contract and usage.
