getBoundary

public Iterable<? extends LatLon> getBoundary(int index)

getBoundaryCount

public int getBoundaryCount()

getLocations

public Iterable<? extends LatLon> getLocations(Globe globe)

Description copied from interface: SurfaceShape

Returns the shape's locations as they appear on the specified globe, or null if the shape has no locations.

Parameters:

globe - the globe the shape is related to.

Returns:

the shapes locations on the globe, or null if the shape has no locations.

getReferencePosition

public Position getReferencePosition()

Description copied from interface: Movable

A position associated with the object that indicates its aggregate geographic position. The chosen position varies among implementers of this interface. For objects defined by a list of positions, the reference position is typically the first position in the list. For symmetric objects the reference position is often the center of the object. In many cases the object's reference position may be explicitly specified by the application.

Specified by:

getReferencePosition in interface Movable

Specified by:

getReferencePosition in interface Movable2

Specified by:

getReferencePosition in class AbstractSurfaceShape

Returns:

the object's reference position, or null if no reference position is available.

handleUnsuccessfulInteriorTessellation

protected void handleUnsuccessfulInteriorTessellation(DrawContext dc)

Overridden to clear the multi-polygon's boundary list upon an unsuccessful tessellation attempt. This ensures the multi-polygon won't attempt to re-tessellate itself each frame.

Overrides:

handleUnsuccessfulInteriorTessellation in class AbstractSurfaceShape

Parameters:

dc - the current DrawContext.
