Calling base class

Revision as of 07:03, 15 March 2023

EAL (Eco Action Language) is fantastic as it allows you to create a complete system without bringing out Visual Studio or C# at all (nothing is wrong with C# – but it is amazing to be able to execute the model alone). It had a limitation: when overriding methods, there was no way to call the base class implementation of the method.

Now that is fixed by introducing the EAL operation “base” – works just as in C#:

Given the OnCreate method (that is called when an object is created).

The RootClass.OnCreate

And the Person.OnCreate

Note the self.base.OnCreate call that calls the superclass implementation of OnCreate (just as in C#)

And when creating a new Person, I get this output:

…as in the RootClass added “RA ” and the Person added “PA”.
