|
|
* This is part of the {@link ApiModel} hierarchy of classes, which are serializable representations of
|
||
|
|
* API declarations. The non-abstract classes (e.g. `ApiClass`, `ApiEnum`, `ApiInterface`, etc.) use
|
||
|
|
* TypeScript "mixin" functions (e.g. `ApiDeclaredItem`, `ApiItemContainerMixin`, etc.) to add various
|
||
|
|
* features that cannot be represented as a normal inheritance chain (since TypeScript does not allow a child class
|
||
|
|
* to extend more than one base class). The "mixin" is a TypeScript merged declaration with three components:
|
||
|
|
* the function that generates a subclass, an interface that describes the members of the subclass, and
|
||
|
|
* a namespace containing static members of the class.
