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.

public static BooleanBinding selectBoolean(Object root,
                                           String... steps)
```
  Creates a binding used to get a member, such as a.b.c. The value of the binding will be c, or false if c could not be reached (due to b not having a c property, b being null, or c not being a boolean etc.).
  All classes and properties used in a select-binding have to be public. If root has JavaFX properties, this call is equivalent to #selectBoolean(javafx.beans.value.ObservableValue, java.lang.String[]), with the {@code root} and {@code step[0]} being substituted with the relevant property object.
  
  Parameters:
  
  root - The root bean.
  
  Returns:

```
  Creates a binding used to get a member, such as a.b.c. The value of the binding will be c, or "" if c could not be reached (due to b not having a c property, b being null, or c not being a String etc.).
  All classes and properties used in a select-binding have to be public. If root has JavaFX properties, this call is equivalent to #selectString(javafx.beans.value.ObservableValue, java.lang.String[]), with the {@code root} and {@code step[0]} being substituted with the relevant property object.

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>
  
  Throws:
  
  NullPointerException - if one of the properties is null

  Type Parameters:

  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.

  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.
