Eclipse Draw2d
3.3

org.eclipse.draw2d
Class RoutingAnimator

java.lang.Object
  extended by

org.eclipse.draw2d.Animator
      extended by
org.eclipse.draw2d.RoutingAnimator
All Implemented Interfaces:
RoutingListener

public class RoutingAnimator
extends Animator
implements RoutingListener

Animates the routing of a connection. The animator will capture the effects of the connection's router, and the play back the placement of the routing, interpolating the intermediate routes.

To use a routing animator, hook it as a routing listener for the connection whose points are to be animated, by calling PolylineConnection.addRoutingListener(RoutingListener). An animator is active only when the Animation utility is activated.

Since:
3.2

Constructor Detail

RoutingAnimator

protected RoutingAnimator()
Constructs a routing animator for use with one or more connections. The default instance ( getDefault() can be used on any number of connections.

Since:
3.2
Method Detail

playbackStarting

public void playbackStarting(
IFigure connection)
Overridden to sync initial and final states.

Overrides:
playbackStarting in class Animator
Parameters:
connection - the figure
See Also:
Animator.playbackStarting(IFigure)

getCurrentState

protected java.lang.Object getCurrentState(
IFigure connection)
Returns the current state of the connection. Currently, this is a copy of the list of points. However this Object could change in future releases and should not be considered API.

Specified by:
getCurrentState in class Animator
Parameters:
connection - the figure
Returns:
the current state
See Also:
Animator.getCurrentState(IFigure)

getDefault

public static 
RoutingAnimator getDefault()
Returns the default instance.

Returns:
the default instance
Since:
3.2

invalidate

public final void invalidate(
Connection conn)
Hooks invalidate for animation purposes.

Specified by:
invalidate in interface RoutingListener
Parameters:
conn - the connection
See Also:
RoutingListener.invalidate(Connection)

playback

protected boolean playback(
IFigure figure)
Plays back the interpolated state.

Overrides:
playback in class Animator
Parameters:
figure - the figure being animated
Returns:
true if playback was successful
See Also:
Animator.playback(IFigure)

postRoute

public final void postRoute(
Connection connection)
Hooks post routing for animation purposes.

Specified by:
postRoute in interface RoutingListener
Parameters:
connection - the routed connection
See Also:
RoutingListener.postRoute(Connection)

remove

public final void remove(
Connection connection)
This callback is unused. Reserved for possible future use.

Specified by:
remove in interface RoutingListener
Parameters:
connection - the connection
See Also:
RoutingListener.remove(Connection)

route

public final boolean route(
Connection conn)
Hooks route to intercept routing during animation playback.

Specified by:
route in interface RoutingListener
Parameters:
conn - the connection being routed
Returns:
true if routing has been performed by the listener
See Also:
RoutingListener.route(Connection)

setConstraint

public final void setConstraint(
Connection connection,
                                java.lang.Object constraint)
This callback is unused. Reserved for possible future use.

Specified by:
setConstraint in interface RoutingListener
Parameters:
connection - the connection
constraint - the new constraint
