# 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>

Type Parameters:
  `K` - the map key type
  `V` - the map value type

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
