Class TransformedNestedListBinding<T,U>

java.lang.Object
javafx.beans.binding.ObjectExpression<U>
javafx.beans.binding.ObjectBinding<U>
com.dlsc.gemsfx.binding.AbstractNestedListBinding<T,U>
com.dlsc.gemsfx.binding.TransformedNestedListBinding<T,U>
Type Parameters:
T - the type of the elements in the nested observable lists
U - the type of the value computed by the binding
All Implemented Interfaces:
javafx.beans.binding.Binding<U>, javafx.beans.Observable, javafx.beans.value.ObservableObjectValue<U>, javafx.beans.value.ObservableValue<U>
public class TransformedNestedListBinding<T,U> extends AbstractNestedListBinding<T,U>
A concrete implementation of AbstractNestedListBinding that computes its value using a function that directly applies to the source list of lists. This class maintains the nested list structure in its computation.

    • TransformedNestedListBinding

      public TransformedNestedListBinding(javafx.collections.ObservableList<javafx.collections.ObservableList<T>> source, Function<javafx.collections.ObservableList<javafx.collections.ObservableList<T>>, U> transformer)
      Constructs a NestedListBinding with a source and a transformer function. The transformer function is applied directly to the nested list structure to compute the value.
      Parameters:
      source - The observable list of observable lists that serves as the source for this binding.
      transformer - A function that transforms the source into a computed value of type U.

  • Method Details

    • computeValue

      protected U computeValue()
      Computes the value of the binding by applying the transformer function to the source. This method directly reflects changes in the nested list structure in the computed value.
      Specified by:
      computeValue in class javafx.beans.binding.ObjectBinding<U>
      Returns:
      The computed value, as transformed from the nested list structure.
