/**
 *
 * SubscribableAbstract
 *
 * This class is part of the SDK.
 * @since 10
 *
 * SubscribableAbstract is an abstract class that manages subscribers
 * to value changes. These subscribers are the implementation of
 * @State, @Link, @Provide, @Consume decorated variables inside the
 * framework. Each using @State, @Link, etc., decorated variable in
 * a @Component will make its own subscription. When the component
 * is created the subscription is added, and before the component
 * is deleted it unsubscribes
 *
 * An application may extend SubscribableAbstract for a custom class
 * that manages state data. @State, @Link, @Provide, @Consume
 * decorated variables can hold an Object that is instance of
 * SubscribableAbstract.
 *
 * About lifecycle: It is legal use for two @Components with two @State
 * decorated variables to share the same SubscribableAbstract object.
 * Each such decorated variable implementation makes its own
 * subscription to the SubscribableAbstract object. Hence, when both variables
 * have unsubscribed the SubscribableAbstract custom class may do its own
 * de-initialization, e.g. release held external resources.
 *
 * How to extend:
 * A subclass manages the get and set to one or several properties on its own.
 * The subclass needs to notify all relevant value changes to the framework for the
 * UI to be updated. Notification should only be given for class properties that
 * are used to generate the UI.
 *
 * A subclass must call super() in its constructor to let this base class
 * initialize itself.
 *
 * A subclass must call 'notifyPropertyHasChanged*(' after the relevant property
 * has changes. The framework will notify all dependent components to re-render.
 *
 * A sub-class may overwrite the 'addOwningProperty' function to add own
 * functionality, but it must call super.addowningOwningProperty(..). E.g.
 * the sub-class could connect to external resources upon the first subscriber.
 *
 * A sub-class may also overwrite the 'removeOwningProperty' function or
 * 'removeOwningPropertyById' function to add own functionality,
 * but it must call super.removeOwningProperty(..).
 * E.g. the sub-class could release held external resources upon loosing the
 * last subscriber.

 *
 * 2- local ObservedObject member property change

 * 3- Rerender of the custom component triggered from the parent

/**
    given parameters for calling a @Builder function
    this function wraps the Object of type T inside a ES6 Proxy.
    Each param, i.e. Object property is either a function or a value.
    If it is a function the function can either return a value of expected
    parameter type or an ObservedPropertyabstract<T> where T is the exected
    parameter type. The latter is the case when passing a state variable by
    reference.

    Two purposes:
    1 - @Builder function boxy accesses params a '$$.paramA'
        However paramA can be a function, so to obtain the value the
        access would need to be '$$.param()' The proxy executes
        the function and return s the result
    2 - said function returns to ObservedPropertyAbstract backing store of
        a calling @Component state variable (whenever the state var is
        provided to the @Builder function). For this case the proxy can provide
        - the value by executing paramA() to return the ObservedPropertyAbstract
          and further (monitored!) get() to read its value
        - when requested to return '__param1' it returns the ObservedPropertyAbstract
          object. The scenario is to use to init a @Link source.
