Interfaces on steroids: polymorphic patterns with AL

Date: 09-11-2022 | From: 16:15 to 18:00 | Room: Hall Z

When you ask Microsoft about interface objects in AL, they'll say that their purpose is to allow binding their implementation to enum objects. That's what they have been designed to support, after all.

However, interfaces can be used to do a lot more than that.

This session will look into interfaces from an architecture perspective, and will show how many nice design patterns such as factory pattern and inversion of control, that were never truly available to C/AL developers of yesterday are natively available to AL developers of today.

Since inversion of control is one of typical testability patterns - those that make writing testable code much easier - this session will shed some light on how to replace some clumsy event-driven approaches to testability with much simpler ones based on interfaces.
