Class NumberExpressionBase

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:: IntegerExpression, LongExpression, FloatExpression, DoubleExpression

NumberExpressionBase

public NumberExpressionBase()

Creates a default NumberExpressionBase.

Method Details

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
