inverseTransform3DPoints
public void inverseTransform3DPoints(double[] srcPts, int srcOff, double[] dstPts, int dstOff, int numPts) throws NonInvertibleTransformExceptionTransforms an array of floating point coordinates by the inverse of this transform. The three coordinate array sections can be exactly the same or can be overlapping sections of the same array without affecting the validity of the results. This method ensures that no source coordinates are overwritten by a previous operation before they can be transformed. The coordinates are stored in the arrays starting at the specified offset in the order[x0, y0, z0, x1, y1, z1, ..., xn, yn, zn]
.- Parameters:
srcPts
- the array containing the source point coordinates. Each point is stored as a triplet of x, y, z coordinates.srcOff
- the offset to the first point to be transformed in the source arraydstPts
- the array into which the transformed point coordinates are returned. Each point is stored as a triplet of x, y, z coordinates.dstOff
- the offset to the location of the first transformed point that is stored in the destination arraynumPts
- the number of points to be transformed- Throws:
NonInvertibleTransformException
- if this transform cannot be invertedNullPointerException
- ifsrcPts
or (@code dstPts} is null- Since:
- JavaFX 8.0

- the inversely transformed relative magnitude vector represented
by a
Point2D
instance - Throws:
IllegalStateException

buildEventDispatchChain
Description copied from interface:EventTarget
Construct an event dispatch chain for this target. The event dispatch chain contains event dispatchers which might be interested in processing of events targeted at thisEventTarget
. This event target is not automatically added to the chain, so if it wants to process events, it needs to add anEventDispatcher
for itself to the chain.In the case the event target is part of some hierarchy, the chain for it is usually built from event dispatchers collected from the root of the hierarchy to the event target.
The event dispatch chain is constructed by modifications to the provided initial event dispatch chain. The returned chain should have the initial chain at its end so the dispatchers should be prepended to the initial chain.
The caller shouldn't assume that the initial chain remains unchanged nor that the returned value will reference a different chain.
- Specified by:
buildEventDispatchChain
in interfaceEventTarget
- Parameters:
tail
- the initial chain to build from- Returns:
- the resulting event dispatch chain for this target
-
addEventHandler
public final <T extends Event> void addEventHandler(EventType<T> eventType, EventHandler<? super T> eventHandler)Registers an event handler to this transform. Any event filters are first processed, then the specified onFoo event handlers, and finally any event handlers registered by this method.
Currently the only event delivered to a
Transform
is theTransformChangedEvent
with it's single typeTRANSFORM_CHANGED
.- Type Parameters:
T
- the specific event class of the handler- Parameters:
eventType
- the type of the events to receive by the handlereventHandler
- the handler to register- Throws:
NullPointerException
- if the event type or handler is null- Since:
- JavaFX 8.0
-
removeEventHandler
public final <T extends Event> void removeEventHandler(EventType<T> eventType, EventHandler<? super T> eventHandler)Unregisters a previously registered event handler from this transform. One handler might have been registered for different event types, so the caller needs to specify the particular event type from which to unregister the handler.- Type Parameters:
T
- the specific event class of the handler- Parameters:
eventType
- the event type from which to unregistereventHandler
- the handler to unregister- Throws:
NullPointerException
- if the event type or handler is null- Since:
- JavaFX 8.0
-
addEventFilter
public final <T extends Event> void addEventFilter(EventType<T> eventType, EventHandler<? super T> eventFilter)Registers an event filter to this transform. Registered event filters get an event before any associated event handlers.
Currently the only event delivered to a
Transform
is theTransformChangedEvent
with it's single typeTRANSFORM_CHANGED
.- Type Parameters:
T
- the specific event class of the filter- Parameters:
eventType
- the type of the events to receive by the filtereventFilter
- the filter to register- Throws:
NullPointerException
- if the event type or filter is null- Since:
- JavaFX 8.0
-
removeEventFilter
public final <T extends Event> void removeEventFilter(EventType<T> eventType, EventHandler<? super T> eventFilter)Unregisters a previously registered event filter from this transform. One filter might have been registered for different event types, so the caller needs to specify the particular event type from which to unregister the filter.- Type Parameters:
T
- the specific event class of the filter- Parameters:
eventType
- the event type from which to unregistereventFilter
- the filter to unregister- Throws:
NullPointerException
- if the event type or filter is null- Since:
- JavaFX 8.0
-
setOnTransformChanged
Sets the onTransformChanged event handler which is called whenever the transform changes any of its parameters.- Parameters:
value
- the event handler, can be null to clear it- Since:
- JavaFX 8.0
-
getOnTransformChanged
Gets the onTransformChanged event handler.- Returns:
- the event handler previously set by
setOnTransformChanged
method, null if the handler is not set. - Since:
- JavaFX 8.0
-
onTransformChangedProperty
public final ObjectProperty<EventHandler<? super TransformChangedEvent>> onTransformChangedProperty()The onTransformChanged event handler is called whenever the transform changes any of its parameters.- Since:
- JavaFX 8.0
- See Also:
getOnTransformChanged()
,setOnTransformChanged(EventHandler)
-
transformChanged
protected void transformChanged()This method must be called by all transforms whenever any of their parameters changes. It is typically called when any of the transform's properties is invalidated (it is OK to skip the call if an invalid property is set).- Since:
- JavaFX 8.0
