Enclosing class:

AbstractSurfaceShape

protected static class AbstractSurfaceShape.SurfaceShapeStateKey
extends AbstractSurfaceObject.SurfaceObjectStateKey

Represents a surface shapes's current state. SurfaceShapeStateKey extends AbstractSurfaceObject.SurfaceObjectStateKey by adding the shape's current ShapeAttributes and the globe's state key.

SurfaceShapeStateKey uniquely identifies a surface shapes's current state exactly as SurfaceObjectStateKey does, but also distinguishes the shape's active ShapeAttributes from any previous attributes, and distinguishes between different globes via the globe state key.

Field Summary

protected ShapeAttributes	attributes The SurfaceShape's attributes.
protected Object	globeStateKey The Globe's state key.

Field Detail

attributes

protected final ShapeAttributes attributes

The SurfaceShape's attributes. May be null if the shape has no attributes.

globeStateKey

protected final Object globeStateKey

The Globe's state key. May be null if the shape's state does not depend on the globe.

Constructor Detail

AbstractSurfaceShape.SurfaceShapeStateKey

public AbstractSurfaceShape.SurfaceShapeStateKey(long uniqueID,
                                                 long modifiedTime,
                                                 ShapeAttributes attributes,
                                                 Object globeStateKey)

Constructs a new SurfaceShapeStateKey with the specified unique ID, modified time, attributes, and globe state key. The globe state key should be null if the surface shape does not depend on the globe.

Parameters:

uniqueID - the SurfaceShape's unique ID.

modifiedTime - the SurfaceShape's modified time.

attributes - the SurfaceShape's attributes, or null if the shape has no attributes.

globeStateKey - the globe's state key, or null if the shape does not depend on the globe.
