Method Detail

addObservableValueExtractor

public static void addObservableValueExtractor(java.util.function.Predicate<javafx.scene.control.Control> test,
                                               javafx.util.Callback<javafx.scene.control.Control,javafx.beans.value.ObservableValue<?>> extract)

Add "obervable value extractor" for custom controls.

Parameters:

test - applicability test

extract - extraction of observable value

getObservableValueExtractor

public static final java.util.Optional<javafx.util.Callback<javafx.scene.control.Control,javafx.beans.value.ObservableValue<?>>> getObservableValueExtractor(javafx.scene.control.Control c)

addValueExtractor

public static void addValueExtractor(java.util.function.Predicate<javafx.scene.Node> test,
                                     javafx.util.Callback<javafx.scene.Node,java.lang.Object> extractor)

getValue

public static java.lang.Object getValue(javafx.scene.Node n)

Attempts to return a value for the given Node. This is done by checking the map of value extractors, contained within this class. This map contains value extractors for common UI controls, but more extractors can be added by calling addObservableValueExtractor(Predicate, Callback).

Parameters:

n - The node from whom a value will hopefully be extracted.

Returns:

The value of the given node.
