Class ObservableValuesListBinding<T,U>

java.lang.Object
javafx.beans.binding.ObjectExpression<U>
javafx.beans.binding.ObjectBinding<U>
com.dlsc.gemsfx.binding.ObservableValuesListBinding<T,U>
Type Parameters:
T - the type held by the ObservableValues in the source list
U - the type of the output value after applying the transformation function
All Implemented Interfaces:
javafx.beans.binding.Binding<U>, javafx.beans.Observable, javafx.beans.value.ObservableObjectValue<U>, javafx.beans.value.ObservableValue<U>
public class ObservableValuesListBinding<T,U> extends javafx.beans.binding.ObjectBinding<U>
This class binds to an ObservableList of ObservableValue objects and updates its value based on the current values of these ObservableValues. It reevaluates its value whenever any of the ObservableValues change. The computed value is determined by applying a transformation function to the list of current values.
