# Class Transform

java.lang.Object
javafx.scene.transform.Transform

All Implemented Interfaces:
  `Cloneable`, `EventTarget`

Direct Known Subclasses:
  `Affine`, `Rotate`, `Scale`, `Shear`, `Translate`

public abstract class Transform extends Object implements Cloneable, EventTarget
This class is a base class for different affine transformations. It provides factory methods for the simple transformations - rotating, scaling, shearing, and translation. It allows to get the transformation matrix elements for any transform.

Example:

      Rectangle rect = new Rectangle(50,50, Color.RED);
      rect.getTransforms().add(new Rotate(45,0,0)); //rotate by 45 degrees

  - ### buildEventDispatchChain

    public EventDispatchChain buildEventDispatchChain(EventDispatchChain tail)
    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 this `EventTarget`. This event target is not automatically added to the chain, so if it wants to process events, it needs to add an `EventDispatcher` 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 interface `EventTarget`
    Parameters:
      `tail` - the initial chain to build from
    Returns:
      the resulting event dispatch chain for this target

    Currently the only event delivered to a `Transform` is the `TransformChangedEvent` with it's single type `TRANSFORM_CHANGED`.

    Type Parameters:
      `T` - the specific event class of the handler
    Parameters:
      `eventType` - the type of the events to receive by the handler

  - ### removeEventHandler

    public final <T extends Event> void removeEventHandler(EventType<T> eventType, EventHandler<? super T> eventHandler)

    Type Parameters:
      `T` - the specific event class of the handler
    Parameters:
      `eventType` - the event type from which to unregister
      `eventHandler` - the handler to unregister

    Type Parameters:
      `T` - the specific event class of the filter
    Parameters:
      `eventType` - the type of the events to receive by the filter
