Method Details

toString

public String toString()

Returns a string representation of this ReadOnlyDoubleProperty object.

readOnlyDoubleProperty

public static <T extends Number>
ReadOnlyDoubleProperty readOnlyDoubleProperty(ReadOnlyProperty<T> property)

Returns a ReadOnlyDoubleProperty that wraps a ReadOnlyProperty. If the ReadOnlyProperty is already a ReadOnlyDoubleProperty, it will be returned. Otherwise a new ReadOnlyDoubleProperty is created that is bound to the ReadOnlyProperty. Note: null values will be interpreted as 0.0

T - The type of Number to be wrapped

Parameters:

property - The source ReadOnlyProperty

Returns:

A ReadOnlyDoubleProperty that wraps the ReadOnlyProperty if necessary

Throws:

NullPointerException - if property is null

Since:

asObject

public ReadOnlyObjectProperty<Double> asObject()

Creates a ReadOnlyObjectProperty that holds the value of this ReadOnlyDoubleProperty. If the value of this ReadOnlyDoubleProperty changes, the value of the ReadOnlyObjectProperty will be updated automatically.

Overrides:

asObject in class DoubleExpression

Returns:

the new ReadOnlyObjectProperty
