IntegerExpression (JavaFX 8)

java.lang.Object
- javafx.beans.binding.NumberExpressionBase
- - javafx.beans.binding.IntegerExpression

All Implemented Interfaces:

NumberExpression, Observable, ObservableIntegerValue, ObservableNumberValue, ObservableValue<Number>

Direct Known Subclasses:

IntegerBinding, ReadOnlyIntegerProperty
```
public abstract class IntegerExpression
extends NumberExpressionBase
implements ObservableIntegerValue
```
A IntegerExpression is a ObservableIntegerValue plus additional convenience methods to generate bindings in a fluent style.
A concrete sub-class of IntegerExpression has to implement the method ObservableIntegerValue.get(), which provides the actual value of this expression.

Since:

JavaFX 2.0

  - integerExpression
```
public static IntegerExpression integerExpression(ObservableIntegerValue value)
```
    Returns a IntegerExpression that wraps a ObservableIntegerValue. If the ObservableIntegerValue is already a IntegerExpression, it will be returned. Otherwise a new IntegerBinding is created that is bound to the ObservableIntegerValue.
    
    Parameters:
    
    value - The source ObservableIntegerValue
    
    Returns:
    
    A IntegerExpression that wraps the ObservableIntegerValue if necessary
    
    Throws:
    
    NullPointerException - if value is null
  - integerExpression
```
public static <T extends Number> IntegerExpression integerExpression(ObservableValue<T> value)
```
    Returns an IntegerExpression that wraps an ObservableValue. If the ObservableValue is already a IntegerExpression, it will be returned. Otherwise a new IntegerBinding is created that is bound to the ObservableValue.
    Note: this method can be used to convert an ObjectExpression or ObjectProperty of specific number type to IntegerExpression, which is essentially an ObservableValue<Number>. See sample below.
    IntegerProperty integerProperty = new SimpleIntegerProperty(1); ObjectProperty<Integer> objectProperty = new SimpleObjectProperty<>(2); BooleanBinding binding = integerProperty.greaterThan(IntegerExpression.integerExpression(objectProperty));
    Note: null values will be interpreted as 0
    Parameters:
    
    value - The source ObservableValue
    
    Returns:
    
    A IntegerExpression that wraps the ObservableValue if necessary
    
    Throws:
    
    NullPointerException - if value is null
