- All Implemented Interfaces:
NumberExpression
,Observable
,ObservableFloatValue
,ObservableNumberValue
,ObservableValue<Number>
- Direct Known Subclasses:
FloatBinding
,ReadOnlyFloatProperty
FloatExpression
is an
ObservableFloatValue
plus additional convenience
methods to generate bindings in a fluent style.
A concrete sub-class of FloatExpression
has to implement the method
ObservableFloatValue.get()
, which provides the
actual value of this expression.

intValue
public int intValue()Description copied from interface:ObservableNumberValue
Returns the value of thisObservableNumberValue
as anint
. If the value is not anint
, a standard cast is performed.- Specified by:
intValue
in interfaceObservableNumberValue
- Returns:
- The value of this
ObservableNumberValue
as anint
-
longValue
public long longValue()Description copied from interface:ObservableNumberValue
Returns the value of thisObservableNumberValue
as along
. If the value is not along
, a standard cast is performed.- Specified by:
longValue
in interfaceObservableNumberValue
- Returns:
- The value of this
ObservableNumberValue
as along
-
floatValue
public float floatValue()Description copied from interface:ObservableNumberValue
Returns the value of thisObservableNumberValue
as afloat
. If the value is not afloat
, a standard cast is performed.- Specified by:
floatValue
in interfaceObservableNumberValue
- Returns:
- The value of this
ObservableNumberValue
as afloat
-
doubleValue
public double doubleValue()Description copied from interface:ObservableNumberValue
Returns the value of thisObservableNumberValue
as adouble
. If the value is not adouble
, a standard cast is performed.- Specified by:
doubleValue
in interfaceObservableNumberValue
- Returns:
- The value of this
ObservableNumberValue
as adouble
-
getValue
Description copied from interface:ObservableValue
Returns the current value of thisObservableValue
- Specified by:
getValue
in interfaceObservableValue<Number>
- Returns:
- The current value
-
floatExpression
Returns aFloatExpression
that wraps aObservableFloatValue
. If theObservableFloatValue
is already aFloatExpression
, it will be returned. Otherwise a newFloatBinding
is created that is bound to theObservableFloatValue
.- Parameters:
value
- The sourceObservableFloatValue
- Returns:
- A
FloatExpression
that wraps theObservableFloatValue
if necessary - Throws:
NullPointerException
- ifvalue
isnull
-
floatExpression
Returns aFloatExpression
that wraps anObservableValue
. If theObservableValue
is already aFloatExpression
, it will be returned. Otherwise a newFloatBinding
is created that is bound to theObservableValue
.Note: this method can be used to convert an
ObjectExpression
orObjectProperty
of specific number type to FloatExpression, which is essentially anObservableValue<Number>
. See sample below.
Note: null values will be interpreted as 0fFloatProperty floatProperty = new SimpleFloatProperty(1.0f); ObjectProperty<Float> objectProperty = new SimpleObjectProperty<>(2.0f); BooleanBinding binding = floatProperty.greaterThan(FloatExpression.floatExpression(objectProperty));
- Type Parameters:
T
- The type of Number to be wrapped- Parameters:
value
- The sourceObservableValue
- Returns:
- A
FloatExpression
that wraps theObservableValue
if necessary - Throws:
NullPointerException
- ifvalue
isnull
