                        AvatarPolicies policies)

Method Detail

resizeResponse

public final PlaneView.ResizeResponse resizeResponse()

Description copied from interface: PlaneView

Does the view adjust its scale or its shape if the viewer facet is resized?

Specified by:

resizeResponse in interface PlaneView

Overrides:

resizeResponse in class PlaneViewWorks

focusAt

public final Point focusAt()

Description copied from interface: ZoomPanView

The last position set with ZoomPanView.setFocusAt(Point).

Specified by:

focusAt in interface ZoomPanView

newFrame

public STarget newFrame()

Overrides:

newFrame in class PlaneViewWorks

originToLeft

public final double originToLeft()

Description copied from interface: ZoomPanView

The unscaled distance from the viewport origin to the left edge of the bounded plane.

Specified by:

originToLeft in interface ZoomPanView

Returns:

any double

originToTop

public final double originToTop()

Description copied from interface: ZoomPanView

The unscaled distance from the viewport origin to the top edge of the bounded plane.

Specified by:

originToTop in interface ZoomPanView

Returns:

any double

planeHeight

public final double planeHeight()

Description copied from interface: ZoomPanView

The unscaled height of the bounded plane.

Specified by:

planeHeight in interface ZoomPanView

Returns:

a positive double

planeWidth

public final double planeWidth()

Description copied from interface: ZoomPanView

The unscaled width of the bounded plane.

Specified by:

planeWidth in interface ZoomPanView

Returns:

a positive double

setFocusAt

public final void setFocusAt(Point at)

Description copied from interface: ZoomPanView

Set a position within the bounded plane that should appear as near as possible to the centre of the viewport.

Specified by:

setFocusAt in interface ZoomPanView

Parameters:

at - should define a position within the bounded plane

setState

public void setState(java.lang.Object state)

Description copied from class: StatefulCore

Implements interface method.

Does not actually set any state, but does change the value returned by StatefulCore.stateStamp(): if updating itself by calling StatefulCore.updateStateStamp(), otherwise by casting src to a Stateful and copying its StatefulCore.stateStamp()

Specified by:

setState in interface Stateful

Overrides:

setState in class PlaneViewWorks

Parameters:

state - must be non-null and interpretable by the implementation as state information; it will usually be another instance of the Stateful's class.

stamp

public final java.lang.Object stamp()

Description copied from interface: PlaneView

Identifier that should change with each change in view properties.

Specified by:

stamp in interface PlaneView

Overrides:

stamp in class PlaneViewWorks

Returns:

typically an Integer containing an auto-incremented value

fetchActorPolicies

protected AvatarPolicies fetchActorPolicies()
