Method Details

bindContentBidirectional
Creates a bidirectional content binding of theObservableMap
, that is wrapped in thisReadOnlyMapProperty
, and anotherObservableMap
.A bidirectional content binding ensures that the content of two
ObservableMaps
is the same. If the content of one of the maps changes, the other one will be updated automatically.- Parameters:
map
- theObservableMap
this property should be bound to- Throws:
NullPointerException
- ifmap
isnull
IllegalArgumentException
- ifmap
is the same map that thisReadOnlyMapProperty
points to
-
unbindContentBidirectional
Deletes a bidirectional content binding between theObservableMap
, that is wrapped in thisReadOnlyMapProperty
, and anotherObject
.- Parameters:
object
- theObject
to which the bidirectional binding should be removed- Throws:
NullPointerException
- ifobject
isnull
IllegalArgumentException
- ifobject
is the same map that thisReadOnlyMapProperty
points to
-
bindContent
Creates a content binding between theObservableMap
, that is wrapped in thisReadOnlyMapProperty
, and anotherObservableMap
.A content binding ensures that the content of the wrapped
ObservableMaps
is the same as that of the other map. If the content of the other map changes, the wrapped map will be updated automatically. Once the wrapped list is bound to another map, you must not change it directly.- Parameters:
map
- theObservableMap
this property should be bound to- Throws:
NullPointerException
- ifmap
isnull
IllegalArgumentException
- ifmap
is the same map that thisReadOnlyMapProperty
points to
-
unbindContent
Deletes a content binding between theObservableMap
, that is wrapped in thisReadOnlyMapProperty
, and anotherObject
.- Parameters:
object
- theObject
to which the binding should be removed- Throws:
NullPointerException
- ifobject
isnull
IllegalArgumentException
- ifobject
is the same map that thisReadOnlyMapProperty
points to
-
equals
-
hashCode
public int hashCode()Returns a hash code for thisReadOnlyMapProperty
object. -
toString
Returns a string representation of thisReadOnlyMapProperty
object.
