Class NumberExpressionBase
- All Implemented Interfaces:
NumberExpression,Observable,ObservableNumberValue,ObservableValue<Number>
- Direct Known Subclasses:
DoubleExpression,FloatExpression,IntegerExpression,LongExpression
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

numberExpression
Returns anNumberExpressionBasethat wraps aObservableNumberValue. If theObservableNumberValueis already an instance ofNumberExpressionBase, it will be returned. Otherwise a newNumberBindingis created that is bound to theObservableNumberValue.- Type Parameters:
S- The type of Number to be wrapped- Parameters:
value- The sourceObservableNumberValue- Returns:
- An
NumberExpressionBasethat wraps theObservableNumberValueif necessary - Throws:
NullPointerException- ifvalueisnull
