/**
 *
 * 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.

/**
    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.

     * this cleanUpId2CmpDeadReferences()
     * id2cmp is a 'map' object id => WeakRef<Object> where object is ViewV2, ViewPU, MonitorV2 or ComputedV2
     * This method iterates over the object entries and deleted all those entries whose value can no longer
     * be deref'ed.
     *
     * cleanUpId2TargetsDeadReferences()
     * is2targets is a 'map' object id => Set<WeakRef<Object>>
     * the method traverses over the object entries and for each value of type
     * Set<WeakRef<Object>> removes all those items from the set that can no longer be deref'ed.
     *
     * According to JS specifications, it is up to ArlTS runtime GC implementation when to collect unreferences objects.
     * Parameters such as available memory, ArkTS processing load, number and size of all JS objects for GC collection
     * can impact the time delay between an object loosing last reference and GC collecting this object.
     *
     * WeakRef deref() returns the object until GC has collected it.
     * The id2cmp and is2targets cleanup herein depends on WeakRef.deref() to return undefined, i.e. it depends on GC
     * collecting 'cmp' or 'target' objects. Only then the algorithm can remove the entry from id2cmp / from id2target.
     * It is therefore to be expected behavior that these map objects grow and they a contain a larger number of
     * MonitorV2, ComputedV2, and/or view model @Observed class objects that are no longer used / referenced by the application.
     * Only after ArkTS runtime GC has collected them, this function is able to clean up the id2cmp and is2targets.

/**
 * JSONCoder
 *
 * The JSONCoder utility enhances the serialization and deserialization capabilities beyond
 * the standard JSON.stringify and JSON.parse methods. While JSON.stringify serializes
 * object properties and their values, it drops functions, class, property, and function decorators,
 * and does not support Map, Set, or Date serialization. JSONCoder addresses these limitations,
 * providing robust support for a wider range of JavaScript features.
 *
 * Main Features:
 * - Adds support for serializing and deserializing class instances, including methods and decorators.
 * - Supports serialization of complex data structures like Map, Set, and Date.
 * - Provides full reconstruction of class instances through the JSONCoder.parseTo method.
 *
 * Usage Scenarios:
 * - Serializing class instances to JSON for network transmission or storage.
 * - Deserializing JSON data back into fully functional class instances, preserving methods and decorators.
 * - Converting JSON data received from network or database into state management observable view models (e.g., @ObservedV2 class objects).
 *
 * The name 'JSONCoder' is derived from the 'JSON stringify/parse', reflecting its purpose to enhance JSON serialization and deserialization for classes.
 *
