## Class ReadOnlyMapWrapper<K,​V>

- java.lang.Object
- - javafx.beans.binding.MapExpression<K,​V>
  - - javafx.beans.property.ReadOnlyMapProperty<K,​V>
    - - javafx.beans.property.MapProperty<K,​V>
      - - javafx.beans.property.MapPropertyBase<K,​V>
        - - javafx.beans.property.SimpleMapProperty<K,​V>
          - - javafx.beans.property.ReadOnlyMapWrapper<K,​V>

- All Implemented Interfaces:
    `Map<K,​V>`, `Observable`, `Property<ObservableMap<K,​V>>`, `ReadOnlyProperty<ObservableMap<K,​V>>`, `ObservableMapValue<K,​V>`, `ObservableObjectValue<ObservableMap<K,​V>>`, `ObservableValue<ObservableMap<K,​V>>`, `WritableMapValue<K,​V>`, `WritableObjectValue<ObservableMap<K,​V>>`, `WritableValue<ObservableMap<K,​V>>`, `ObservableMap<K,​V>`

      public class ReadOnlyMapWrapper<K,​V>
      extends SimpleMapProperty<K,​V>

  This class provides a convenient class to define read-only properties. It creates two properties that are synchronized. One property is read-only and can be passed to external users. The other property is read- and writable and should be used internally only.
  Since:
    JavaFX 2.1

- - ### Constructor Detail

    - #### ReadOnlyMapWrapper

          public ReadOnlyMapWrapper()

      The constructor of `ReadOnlyMapWrapper`

      The constructor of `ReadOnlyMapWrapper`
      Parameters:
        `initialValue` - the initial value of the wrapped value

    - #### ReadOnlyMapWrapper

          public ReadOnlyMapWrapper​(Object bean,
                                    String name)

      The constructor of `ReadOnlyMapWrapper`
      Parameters:
        `bean` - the bean of this `ReadOnlyMapWrapper`
        `name` - the name of this `ReadOnlyMapWrapper`

    - #### ReadOnlyMapWrapper

          public ReadOnlyMapWrapper​(Object bean,
                                    String name,
                                    ObservableMap<K,​V> initialValue)

      The constructor of `ReadOnlyMapWrapper`
      Parameters:
        `bean` - the bean of this `ReadOnlyMapWrapper`
        `name` - the name of this `ReadOnlyMapWrapper`
        `initialValue` - the initial value of the wrapped value

  - ### Method Detail

    - #### getReadOnlyProperty

          public ReadOnlyMapProperty<K,​V> getReadOnlyProperty()

      Returns the readonly property, that is synchronized with this `ReadOnlyMapWrapper`.
      Returns:
        the readonly property

    - #### fireValueChangedEvent

          protected void fireValueChangedEvent()

      Sends notifications to all attached `InvalidationListeners`, `ChangeListeners`, and `MapChangeListener`. This method is called when the value is changed, either manually by calling `MapPropertyBase.set(javafx.collections.ObservableMap)` or in case of a bound property, if the binding becomes invalid.
      Overrides:
        `fireValueChangedEvent` in class `MapPropertyBase<K,​V>`

    - #### fireValueChangedEvent

          protected void fireValueChangedEvent​(MapChangeListener.Change<? extends K,​? extends V> change)

      Sends notifications to all attached `InvalidationListeners`, `ChangeListeners`, and `MapChangeListener`. This method is called when the content of the list changes.
      Overrides:
        `fireValueChangedEvent` in class `MapPropertyBase<K,​V>`
      Parameters:
        `change` - the change that needs to be propagated
