javafx.collections.ObservableSet

Packages that use ObservableSet
Package | Description
--- | ---
javafx.beans.binding | Provides classes that create and operate on a `Binding` that calculates a value that depends on one or more sources.
javafx.beans.property | The package `javafx.beans.property` defines read-only properties and writable properties, plus a number of implementations.
javafx.beans.value | The package `javafx.beans.value` contains the two fundamental interfaces `ObservableValue` and `WritableValue` and all of its sub-interfaces.
javafx.collections | Contains the essential JavaFX collections and collection utilities

javafx.scene.control | The JavaFX User Interface Controls (UI Controls or just Controls) are specialized Nodes in the JavaFX Scenegraph especially suited for reuse in many different application contexts.

- ## Uses of ObservableSet in javafx.beans.binding

  Classes in javafx.beans.binding that implement ObservableSet
  Modifier and Type | Class | Description
  --- | --- | ---
  `class` | `SetBinding<E>` | Base class that provides most of the functionality needed to implement a `Binding` of an `ObservableSet`.
  `class` | `SetExpression<E>` | `SetExpression` is an `ObservableSetValue` plus additional convenience methods to generate bindings in a fluent style.

  Methods in javafx.beans.binding that return ObservableSet
  Modifier and Type | Method | Description
  --- | --- | ---
  `protected abstract ObservableSet<E>` | SetBinding.`computeValue()` | Calculates the current value of this binding.
  `ObservableSet<E>` | SetBinding.`get()` | Returns the result of `SetBinding.computeValue()`.

  Methods in javafx.beans.binding with parameters of type ObservableSet
  Modifier and Type | Method | Description
  --- | --- | ---
  `static <E> void` | Bindings.`bindContent​(Set<E> set1, ObservableSet<? extends E> set2)` | Generates a content binding between an `ObservableSet` and a `Set`.
  `static <E> void` | Bindings.`bindContentBidirectional​(ObservableSet<E> set1, ObservableSet<E> set2)` | Generates a bidirectional binding (or "bind with inverse") between two instances of `ObservableSet`.
  `static <E> BooleanBinding` | Bindings.`isEmpty​(ObservableSet<E> op)` | Creates a new `BooleanBinding` that holds `true` if a given `ObservableSet` is empty.
  `BooleanBinding` | SetExpression.`isEqualTo​(ObservableSet<?> other)` | Creates a new `BooleanBinding` that holds `true` if this set is equal to another `ObservableSet`.
  `static <E> BooleanBinding` | Bindings.`isNotEmpty​(ObservableSet<E> op)` | Creates a new `BooleanBinding` that holds `true` if a given `ObservableSet` is not empty.
  `BooleanBinding` | SetExpression.`isNotEqualTo​(ObservableSet<?> other)` | Creates a new `BooleanBinding` that holds `true` if this set is not equal to another `ObservableSet`.
  `static <E> IntegerBinding` | Bindings.`size​(ObservableSet<E> op)` | Creates a new `IntegerBinding` that contains the size of an `ObservableSet`.

  `class` | `ReadOnlySetPropertyBase<E>` | Base class for all readonly properties wrapping an `ObservableSet`.
  `class` | `ReadOnlySetWrapper<E>` | This class provides a convenient class to define read-only properties.
  `class` | `SetProperty<E>` | This class provides a full implementation of a `Property` wrapping an `ObservableSet`.
  `class` | `SetPropertyBase<E>` | The class `SetPropertyBase` is the base class for a property wrapping an `ObservableSet`.
  `class` | `SimpleSetProperty<E>` | This class provides a full implementation of a `Property` wrapping an `ObservableSet`.

  Modifier and Type | Method | Description
  --- | --- | ---
  `void` | ReadOnlySetProperty.`bindContent​(ObservableSet<E> set)` | Creates a content binding between the `ObservableSet`, that is wrapped in this `ReadOnlySetProperty`, and another `ObservableSet`.
  `void` | ReadOnlySetProperty.`bindContentBidirectional​(ObservableSet<E> set)` | Creates a bidirectional content binding of the `ObservableSet`, that is wrapped in this `ReadOnlySetProperty`, and another `ObservableSet`.
