Modifier and Type	Method and Description
static javafx.beans.binding.BooleanBinding	conditionBinding(javafx.beans.value.ObservableStringValue op, Predicate<String> predicate) Create an unidirectional boolean binding that resolves a given ObservableStringValue by a given predicate.
static javafx.beans.binding.StringBinding	mappingBinding(javafx.beans.value.ObservableStringValue op, Function<String,String> mapping) Create an unidirectional String binding that resolves a given ObservableStringValue by a given String-to-String mapping.
static javafx.beans.binding.StringBinding	resolvingBinding(javafx.beans.value.ObservableStringValue op1, javafx.beans.value.ObservableStringValue op2, BiFunction<String,String,String> resolving) Create an unidirectional String binding that resolves two given ObservableStringValues by a BiFunction that creates a combined String value from both provied inputs.

Method Detail

conditionBinding

public static javafx.beans.binding.BooleanBinding conditionBinding(javafx.beans.value.ObservableStringValue op,
                                                                   Predicate<String> predicate)

Create an unidirectional boolean binding that resolves a given ObservableStringValue by a given predicate. Whenever the String value changes, the predicate is reevaluated and all observers of the returned binding are notified of the predicate change.

Parameters:

op - observable String

predicate - String predicate

Returns:

boolean binding that reflects the predicate on the String

mappingBinding

public static javafx.beans.binding.StringBinding mappingBinding(javafx.beans.value.ObservableStringValue op,
                                                                Function<String,String> mapping)

Create an unidirectional String binding that resolves a given ObservableStringValue by a given String-to-String mapping. Whenever the String value changes, the mapping is computed again and all observers of the returned binding are notified of the change.

Parameters:

op - observable String

mapping - String-to-String mapping

Returns:

String binding that reflects the mapping on the String

resolvingBinding

public static javafx.beans.binding.StringBinding resolvingBinding(javafx.beans.value.ObservableStringValue op1,
                                                                  javafx.beans.value.ObservableStringValue op2,
                                                                  BiFunction<String,String,String> resolving)

Create an unidirectional String binding that resolves two given ObservableStringValues by a BiFunction that creates a combined String value from both provied inputs. Whenever one of the String values change, the resolving function is computed again and all observers of the returned binding are notified of the change.

Parameters:

op1 - first observable String (will be put as first parameter of resolving function)

op2 - second observable String (will be put as second parameter of resolving function)

resolving - resolving Bifunction

Returns:

String binding that reflects the combination of the Strings
