java.lang.Object
javafx.beans.binding.SetExpression<E>
- Type Parameters:
E
- the type of theSet
elements
- All Implemented Interfaces:
Iterable<E>
,Collection<E>
,Set<E>
,Observable
,ObservableObjectValue<ObservableSet<E>>
,ObservableSetValue<E>
,ObservableValue<ObservableSet<E>>
,ObservableSet<E>
- Direct Known Subclasses:
ReadOnlySetProperty
,SetBinding
SetExpression
is an
ObservableSetValue
plus additional convenience
methods to generate bindings in a fluent style.
A concrete sub-class of SetExpression
has to implement the method
ObservableObjectValue.get()
, which provides the
actual value of this expression.
If the wrapped list of a SetExpression
is null
, all methods implementing the Set
interface will behave as if they were applied to an immutable empty set.
- Since:
- JavaFX 2.1

Method Details
-
getValue
Description copied from interface:ObservableValue
Returns the current value of thisObservableValue
- Specified by:
getValue
in interfaceObservableValue<E>
- Returns:
- The current value
-
setExpression
Returns aSetExpression
that wraps aObservableSetValue
. If theObservableSetValue
is already aSetExpression
, it will be returned. Otherwise a newSetBinding
is created that is bound to theObservableSetValue
.- Type Parameters:
E
- the type of theSet
elements- Parameters:
value
- The sourceObservableSetValue
- Returns:
- A
SetExpression
that wraps theObservableSetValue
if necessary - Throws:
NullPointerException
- ifvalue
isnull
-
getSize
public int getSize()The size of the set- Returns:
- the size
-
sizeProperty
An integer property that represents the size of the set.- Returns:
- the property
- See Also:
-
emptyProperty
A boolean property that istrue
, if the set is empty.- Returns:
- the
ReadOnlyBooleanProperty
- See Also:

isEqualTo
- Parameters:
other
- the otherObservableSet
- Returns:
- the new
BooleanBinding
- Throws:
NullPointerException

isNotEqualTo
- Parameters:
other
- the otherObservableSet
- Returns:
- the new
BooleanBinding
- Throws:
NullPointerException
- ifother
isnull
-
isNull
- Returns:
- the new
BooleanBinding
-
isNotNull
- Returns:
- the new
BooleanBinding
-
asString
Creates aStringBinding
that holds the value of theSetExpression
turned into aString
. If the value of thisSetExpression
changes, the value of theStringBinding
will be updated automatically.- Returns:
- the new
StringBinding
-
