NumberExpressionBase (Java SE 10 & JDK 10 )

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

All Implemented Interfaces:

NumberExpression, Observable, ObservableNumberValue, ObservableValue<Number>

Direct Known Subclasses:

DoubleExpression, FloatExpression, IntegerExpression, LongExpression
```
public abstract class NumberExpressionBase
extends Object
implements NumberExpression
```
NumberExpressionBase contains convenience methods to generate bindings in a fluent style, that are common to all NumberExpression subclasses.
NumberExpressionBase serves as a place for common code of specific NumberExpression subclasses for the specific number type.

Since:

JavaFX 2.0

See Also:

public NumberExpressionBase()
```
- Method Detail
  - numberExpression
```
public static <S extends Number> NumberExpressionBase numberExpression(ObservableNumberValue value)
```
    Returns an NumberExpressionBase that wraps a ObservableNumberValue. If the ObservableNumberValue is already an instance of NumberExpressionBase, it will be returned. Otherwise a new NumberBinding is created that is bound to the ObservableNumberValue.
    
    Type Parameters:
    
    S - The type of Number to be wrapped
    
    Parameters:
    
    value - The source ObservableNumberValue
    
    Returns:
    
    An NumberExpressionBase that wraps the ObservableNumberValue if necessary
    
    Throws:
    
    NullPointerException - if value is null
