ImplementsILayoutAlgorithm

This is an implementation of an Inverted Self Organizing Map (ISOM) layout.


Public Properties
 PropertyDefined by
 InheritedanimInProgress : Boolean
Indicator if currently an animation sequence is still in progress.
BaseLayouter
 InheritedautoFitEnabled : Boolean
BaseLayouter
 InheriteddisableAnimation : Boolean
If set to true, animation is disabled and direct node location setting occurs (instantaneously).
BaseLayouter
 Inheritedgraph : IGraph
Assign a Graph datastructure object to the layouter, every layouter will need one to work and some may allow to set it in their constructor
BaseLayouter
 InheritedlayoutChanged : Boolean
BaseLayouter
 InheritedlinkLength : Number
This is a NOP in the BaseLayouter class.
BaseLayouter
 Inheritedvgraph : IVisualGraph
Assign a VisualGraph object to the layouter, every layouter will need one to work, some may also offer to set it in their constructor.
BaseLayouter
Protected Properties
 PropertyDefined by
 Inherited_autoFitEnabled : Boolean = false
The indicator if AutoFit should currently be used or not.
BaseLayouter
 InheritedcurrentDrawing : BaseLayoutDrawing
Allow to set the reference to the drawing object from derived classes.
BaseLayouter
 Inherited_disableAnimation : Boolean = false
If set to true, animation is disabled and direct node location setting occurs (instantaneously).
BaseLayouter
 Inherited_dragNode : IVisualNode = null
IterativeBaseLayouter
 Inherited_graph : IGraph = null
All layouters need access to the Graph.
BaseLayouter
 Inherited_layoutChanged : Boolean = false
This keeps track if the layout has changed and can be accessed by any derived layouter.
BaseLayouter
 Inherited_root : INode
The current root node of the layout.
BaseLayouter
 Inherited_stree : IGTree
A spanning tree of the graph, since probably every layout will work on a spanning tree, we keep this one in this base class.
BaseLayouter
 Inherited_vgraph : IVisualGraph = null
All layouters need access to the VisualGraph.
BaseLayouter
