Class Bindings

java.lang.Object
javafx.beans.binding.Bindings

public final class Bindings extends Object
Bindings is a helper class with a lot of utility functions to create simple bindings.

Usually there are two possibilities to define the same operation: the Fluent API and the the factory methods in this class. This allows a developer to define complex expression in a way that is most easy to understand. For instance the expression result = a*b + c*d can be defined using only the Fluent API:

DoubleBinding result = a.multiply(b).add(c.multiply(d));

Or using only factory methods in Bindings:

NumberBinding result = add (multiply(a, b), multiply(c,d));

Or mixing both possibilities:

NumberBinding result = add (a.multiply(b), c.multiply(d));

The main difference between using the Fluent API and using the factory methods in this class is that the Fluent API requires that at least one of the operands is an Expression (see javafx.beans.binding). (Every Expression contains a static method that generates an Expression from an ObservableValue.)

Also if you watched closely, you might have noticed that the return type of the Fluent API is different in the examples above. In a lot of cases the Fluent API allows to be more specific about the returned type (see NumberExpression for more details about implicit casting.

Deploying an Application as a Module

If any class used in a select-binding (see the various select* methods) is in a named module, then it must be reflectively accessible to the javafx.base module. A class is reflectively accessible if the module opens the containing package to at least the javafx.base module.

For example, if com.foo.MyClass is in the foo.app module, the module-info.java might look like this:

module foo.app {
    opens com.foo to javafx.base;
}

Alternatively, a class is reflectively accessible if the module exports the containing package unconditionally.

      Note: since 8.0, JavaBeans properties are supported and might be in the chain.

    • bindBidirectional

      public static <T> void bindBidirectional(Property<T> property1, Property<T> property2)
      Generates a bidirectional binding (or "bind with inverse") between two instances of Property.

      A bidirectional binding is a binding that works in both directions. If two properties a and b are linked with a bidirectional binding and the value of a changes, b is set to the same value automatically. And vice versa, if b changes, a is set to the same value.

      A bidirectional binding can be removed with unbindBidirectional(Property, Property).

      Note: this implementation of a bidirectional binding behaves differently from all other bindings here in two important aspects. A property that is linked to another property with a bidirectional binding can still be set (usually bindings would throw an exception). Secondly bidirectional bindings are calculated eagerly, i.e. a bound property is updated immediately.

      Type Parameters:
      T - the types of the properties
      Parameters:
      property1 - the first Property<T>
      property2 - the second Property<T>

      Generates a bidirectional binding (or "bind with inverse") between a String-Property and another Property using the specified Format for conversion.

      A bidirectional binding is a binding that works in both directions. If two properties a and b are linked with a bidirectional binding and the value of a changes, b is set to the same value automatically. And vice versa, if b changes, a is set to the same value.

      A bidirectional binding is a binding that works in both directions. If two properties a and b are linked with a bidirectional binding and the value of a changes, b is set to the same value automatically. And vice versa, if b changes, a is set to the same value.

      public static <E> void bindContentBidirectional(ObservableList<E> list1, ObservableList<E> list2)
      Generates a bidirectional binding (or "bind with inverse") between two instances of ObservableList.

      A bidirectional binding is a binding that works in both directions. If two properties a and b are linked with a bidirectional binding and the value of a changes, b is set to the same value automatically. And vice versa, if b changes, a is set to the same value.

      Only the content of the two lists is synchronized, which means that both lists are different, but they contain the same elements.

      Note: this implementation of a bidirectional binding behaves differently from all other bindings here in two important aspects. A property that is linked to another property with a bidirectional binding can still be set (usually bindings would throw an exception). Secondly bidirectional bindings are calculated eagerly, i.e. a bound property is updated immediately.

      Type Parameters:
      E - the type of the set elements
      Parameters:
      set1 - the first ObservableSet<E>
      set2 - the second ObservableSet<E>

    • bindContent

      public static <E> void bindContent(List<E> list1, ObservableList<? extends E> list2)
      Generates a content binding between an ObservableList and a List.

      A content binding ensures that the List contains the same elements as the ObservableList. If the content of the ObservableList changes, the List will be updated automatically.

      Once a List is bound to an ObservableList, the List must not be changed directly anymore. Doing so would lead to unexpected results.

      A content-binding can be removed with unbindContent(Object, Object).

      Type Parameters:
      E - the type of the List elements
      Parameters:
      list1 - the List
      list2 - the ObservableList
      Since:
      JavaFX 2.1
    • bindContent

      public static <E> void bindContent(Set<E> set1, ObservableSet<? extends E> set2)
      Generates a content binding between an ObservableSet and a Set.

      A content binding ensures that the Set contains the same elements as the ObservableSet. If the content of the ObservableSet changes, the Set will be updated automatically.

      Once a Set is bound to an ObservableSet, the Set must not be changed directly anymore. Doing so would lead to unexpected results.

      A content-binding can be removed with unbindContent(Object, Object).

      Type Parameters:
      E - the type of the Set elements
      Parameters:
      set1 - the Set
      set2 - the ObservableSet
      Throws:
      NullPointerException - if one of the sets is null
      IllegalArgumentException - if set1 == set2

      JavaFX 2.1
    • bindContent

      public static <K, V> void bindContent(Map<K,V> map1, ObservableMap<? extends K,? extends V> map2)
      Generates a content binding between an ObservableMap and a Map.

      A content binding ensures that the Map contains the same elements as the ObservableMap. If the content of the ObservableMap changes, the Map will be updated automatically.

      Once a Map is bound to an ObservableMap, the Map must not be changed directly anymore. Doing so would lead to unexpected results.

      A content-binding can be removed with unbindContent(Object, Object).

      Type Parameters:
      K - the type of the key elements of the Map
      V - the type of the value elements of the Map
      Parameters:
      map1 - the Map
      map2 - the ObservableMap
      Throws:
      NullPointerException - if one of the maps is null
      IllegalArgumentException - if map1 == map2
      Since:
      JavaFX 2.1
    • unbindContent

      public static void unbindContent(Object obj1, Object obj2)
