    As of 8.0, no direct replacement available. You can use Map directly as an item for Binder or DataProvider and access item properties with lambdas like binder.forField(component).bind(...) or new Grid<Map<...>>(dataProvider).addColumn(map->map.get(...)).
    Class for handling a set of identified Properties. The elements contained in a MapItem can be referenced using locally unique identifiers. The class supports listeners who are interested in changes to the Property set managed by the class.

      • getListeners

        public Collection<?> getListeners​(Class<?> eventType)
        Deprecated.

      • clone

        public Object clone()
             throws CloneNotSupportedException
        Deprecated.
        Creates and returns a copy of this object.

        The method clone performs a shallow copy of the PropertysetItem.

        Note : All arrays are considered to implement the interface Cloneable. Otherwise, this method creates a new instance of the class of this object and initializes all its fields with exactly the contents of the corresponding fields of this object, as if by assignment, the contents of the fields are not themselves cloned. Thus, this method performs a "shallow copy" of this object, not a "deep copy" operation.

        Overrides:
        clone in class Object
        Throws:
        CloneNotSupportedException - if the object's class does not support the Cloneable interface.
