Constructor Detail

AbstractViewSpace

public AbstractViewSpace()

Creates an instance. Master constructor.

Method Detail

newViewConfigDelegate

protected ViewSpaceConfig newViewConfigDelegate()

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

Returns:

New uninitialized delegate. Never null.

newViewRootDelegate

protected GraphicSpaceRoot newViewRootDelegate()

Called during initialization as the factory method for the view 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.

getViewSpaceConfig

public ViewSpaceConfig getViewSpaceConfig()

Description copied from interface: ViewSpace

Gets the configuration delegate for this view space.

Specified by:

getViewSpaceConfig in interface ViewSpace

Returns:

Reference to the delegate. Never null.

getViewSpaceRoot

public GraphicSpaceRoot getViewSpaceRoot()

Description copied from interface: ViewSpace

Gets the view space tree root.

Specified by:

getViewSpaceRoot in interface ViewSpace

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.
