Class DoubleExpression

java.lang.Object

javafx.beans.binding.NumberExpressionBase

javafx.beans.binding.DoubleExpression

All Implemented Interfaces:

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

Direct Known Subclasses:

DoubleBinding, ReadOnlyDoubleProperty

public abstract class DoubleExpression
extends NumberExpressionBase
implements ObservableDoubleValue

A DoubleExpression is a ObservableDoubleValue plus additional convenience methods to generate bindings in a fluent style.

A concrete sub-class of DoubleExpression has to implement the method ObservableDoubleValue.get(), which provides the actual value of this expression.

Since:

JavaFX 2.0

Method Details

intValue

public int intValue()

Description copied from interface: ObservableNumberValue

Returns the value of this ObservableNumberValue as an int . If the value is not an int, a standard cast is performed.

Specified by:

intValue in interface ObservableNumberValue

Returns:

The value of this ObservableNumberValue as an int

longValue

public long longValue()

Description copied from interface: ObservableNumberValue

Returns the value of this ObservableNumberValue as a long . If the value is not a long, a standard cast is performed.

Specified by:

longValue in interface ObservableNumberValue

Returns:

The value of this ObservableNumberValue as a long

floatValue

public float floatValue()

Description copied from interface: ObservableNumberValue

Returns the value of this ObservableNumberValue as a float. If the value is not a float, a standard cast is performed.

Specified by:

floatValue in interface ObservableNumberValue

Returns:

The value of this ObservableNumberValue as a float

doubleValue

public double doubleValue()

Description copied from interface: ObservableNumberValue

Returns the value of this ObservableNumberValue as a double. If the value is not a double, a standard cast is performed.

Specified by:

doubleValue in interface ObservableNumberValue

Returns:

The value of this ObservableNumberValue as a double

getValue

public Double getValue()

Description copied from interface: ObservableValue

Returns the current value of this ObservableValue

Specified by:

getValue in interface ObservableValue<Number>

Returns:

The current value
