If you create a custom component inherited from a Wijmo component, you can override this method and perform necessary initializations that you usually do in a class constructor. This method is called in the last line of a Wijmo component constructor and allows you to not declare your custom component's constructor at all, thus preventing you from a necessity to maintain constructor parameters and keep them in synch with Wijmo component's constructor parameters.

name: string
The annotation's name.
Returns AnnotationBase
