Constructor Detail

AbstractDisplaySpace

public AbstractDisplaySpace()

Creates an instance. Master constructor.

Method Detail

newDisplayConfigDelegate

protected DisplaySpaceConfig newDisplayConfigDelegate()

Called during initialization as the factory method for the display space configuration delegate. Default implementation: Returns a new AbstractDisplaySpaceConfig.

Returns:

New uninitialized delegate. Never null.

newDisplayRootDelegate

protected GraphicSpaceRoot newDisplayRootDelegate()

Called during initialization as the factory method for the world space tree node delegate. Will be wrapped as a root node. Default implementation: Returns a new AbstractGraphicSpaceRoot with a new AbstractTreeNode.Auto delegate in a new TreeNodes.Tree relationship.

Returns:

New uninitialized delegate. Never null.

getDisplaySpaceConfig

public DisplaySpaceConfig getDisplaySpaceConfig()

Description copied from interface: DisplaySpace

Gets the configuration delegate for this display space.

Specified by:

getDisplaySpaceConfig in interface DisplaySpace

Returns:

Reference to the delegate. Never null.

getDisplaySpaceRoot

public GraphicSpaceRoot getDisplaySpaceRoot()

Description copied from interface: DisplaySpace

Gets the display space tree root.

Specified by:

getDisplaySpaceRoot in interface DisplaySpace

Returns:

Reference to the node. Never null.

getGraphic

public java.lang.Object getGraphic()

Default implementation: Returns this object (non-native direct implementation).

Specified by:

getGraphic in interface Graphic

Returns:

The target graphic object. Possibly this object (self-proxy, direct implementation), but never null.
