TCE objects

A TCE object is an object instance created of a TCE class at runtime. There is no limit in creating TCE objects of any TCE class. TCE objects will be maintained by an object definition in the class or a local TCE object variable.

Supposing, there is a class structure as defined below:

The class Cars is defining features deriving to the whole class structure:

Now you are deciding to create an object of the Cars classes on runtime.

You will create another class holding the object definition:

Now you have two possibilities to define the object definition in the class Car dealer:

First possibilty:

The object definition is placed below Ordered objects. With this definition place, the object created on runtime has a valid object order.

Second possibility:

Defined on this place below Features and unordered objects the object will not have a valid object order.

If you do not define an initialization for the object definition, the variable Cars will be NoValue on runtime.

Define an initialization yet:

With this initialization, there will be an object of class BMW when an object of class Car Dealer is created.

When you take a look into the properties of the object definition of Cars, you will see the property TCE class, or let’s say definition class of the variable:

An object variable of a distinct type (here: Cars) can create objects of all classes below the definition class or the class itself. In our sample these are the classes: ::Cars, ::Mercedes, ::BMW, ::Honda, ::Crysler

If you like to initialize an object definition in one of your functions, use the following:

Cars := ::Mercedes

If you like to create an object in scope of a function, do the following:

Dim ObCars As ::Cars

ObCars := New ::Mercedes

If you like to check the type of object, which is currently set to a TCE object variable, use:

Dim IsMercedes As Boolean

IsMercedes := Cars IsA ::Mercedes

If you like to access a feature of an object, use the Dot operator:

Dim Model As String

Model := Cars.CarModel
