public static void addObservableValueExtractor(Predicate<Control> test, Callback<Control, ObservableValue<?>> extract)

Add "obervable value extractor" for custom controls.

Parameters
test:Predicate<Control>

applicability test

extract:Callback<Control, ObservableValue<?>>

extraction of observable value

public static final Optional<Callback<Control, ObservableValue<?>>> getObservableValueExtractor(final Control c)
getValueback to summary
public static Object getValue(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:Node

The node from whom a value will hopefully be extracted.

Returns:Object

The value of the given node.
