Northwoods.Go.Layout Namespace

In This Topic

The GoLayout for .NET class library is a set of classes built to interface with the GoDiagram for .NET class library and provide support for automatically laying out graphs (node & arc diagrams) by positioning the nodes and routing the links.

Although the classes in the GoLayout class library are not subclasses of classes in the Go class library, many aspects of the layout routines take advantage of the fact that Go objects are targets of the layout.

GoLayout currently supports three general auto-layout routines: a force-directed auto-layout routine, a layered-digraph auto-layout routine, and a tree auto-layout routine. The force-directed auto-layout routine is intended for use with all types of graph – undirected graphs as well as directed graphs. The layered-digraph and tree auto-layout routines are intended specifically for use with directed graphs, including trees and hierarchies.

Classes

	Class	Description
	GoLayout	GoLayout provides a common super-class for auto-layout algorithms. The key aspects of an auto-layout algorithm are an input Northwoods.Go.GoDocument and a PerformLayout method.
	GoLayoutForceDirected	GoLayoutForceDirected provides an auto-layout algorithm for graphs which utilizes a force-directed method.
	GoLayoutForceDirectedLink	Holds auto-layout specific link data.
	GoLayoutForceDirectedNetwork	This provides an abstract view of a Northwoods.Go.IGoCollection as a network (graph) of nodes and directed links. These nodes and links correspond to Northwoods.Go.GoObjects provided in the Northwoods.Go.IGoCollection. This class provides a framework for manipulating the state of nodes and links without modifying the structure of the original document.
	GoLayoutForceDirectedNode	Holds auto-layout specific node data.
	GoLayoutGenericNetwork<N,L,Y>	This provides an abstract view of a Northwoods.Go.IGoCollection as a network (graph) of nodes and directed links. These nodes and links correspond to Northwoods.Go.GoObjects provided in the Northwoods.Go.IGoCollection. This class provides a framework for manipulating the state of nodes and links without modifying the structure of the original document.
	GoLayoutGenericNetwork.Link<N,L,Y>	Holds auto-layout specific link data.
	GoLayoutGenericNetwork.Node<N,L,Y>	Holds auto-layout specific node data.
	GoLayoutLayeredDigraph	GoLayoutLayeredDigraph provides an auto-layout for layered drawings of directed graphs.
	GoLayoutLayeredDigraphLink	Holds auto-layout specific link data.
	GoLayoutLayeredDigraphNetwork	This provides an abstract view of a Northwoods.Go.IGoCollection as a network (graph) of nodes and directed links. These nodes and links correspond to Northwoods.Go.GoObjects provided in the Northwoods.Go.IGoCollection. This class provides a framework for manipulating the state of nodes and links without modifying the structure of the original document.
	GoLayoutLayeredDigraphNode	Holds auto-layout specific node data.
	GoLayoutNetwork	This provides an abstract view of a Northwoods.Go.IGoCollection as a network (graph) of nodes and directed links. These nodes and links correspond to Northwoods.Go.GoObjects provided in the Northwoods.Go.IGoCollection. This class provides a framework for manipulating the state of nodes and links without modifying the structure of the original document.
	GoLayoutNetworkLink	Holds auto-layout specific link data.
	GoLayoutNetworkNode	Holds auto-layout specific node data.
	GoLayoutProgressEventArgs	Holds information for the GoLayout.Progress event.
	GoLayoutRandom	GoLayoutRandom provides an auto-layout algorithm which randomly positions nodes in the document.
	GoLayoutTree	Position nodes in a tree-like arrangement.
	GoLayoutTreeLink	Holds auto-layout specific link data.
	GoLayoutTreeNetwork	This provides an abstract view of a Northwoods.Go.IGoCollection as a network (graph) of nodes and directed links. These nodes and links correspond to Northwoods.Go.GoObjects provided in the Northwoods.Go.IGoCollection. This class provides a framework for manipulating the state of nodes and links without modifying the structure of the original document.
	GoLayoutTreeNode	Holds auto-layout specific node data.

Interfaces

	Interface	Description
	IGoLayoutNetworkLink	Each kind of GoLayoutGenericNetwork<N,L,Y> will have links that implement this interface.
	IGoLayoutNetworkNode	Each kind of GoLayoutGenericNetwork<N,L,Y> will have nodes that implement this interface.

Structures

	Structure	Description
	GoLayoutGenericNetwork.Enumerator<N,L,Y,T>	Enumerator implements both `IEnumerator` and `IEnumerable`.

Delegates

	Delegate	Description
	GoLayoutProgressEventHandler	Represents methods that handle GoLayoutProgressEventArgs.

Enumerations

	Enumeration	Description
	GoLayoutDirection	This enumeration specifies the general direction in which the automatic layout algorithm will position nodes.
	GoLayoutLayeredDigraphAggressive	This enumeration controls how much effort GoLayoutLayeredDigraph.ReduceCrossings puts into trying to look for link crossings.
	GoLayoutLayeredDigraphCycleRemove	This enumeration controls how GoLayoutLayeredDigraph.RemoveCycles changes the graph to make sure it contains no cycles or loops.
	GoLayoutLayeredDigraphInitIndices	This enumeration controls how GoLayoutLayeredDigraph.InitializeIndices determines the array of indices for each layer.
	GoLayoutLayeredDigraphLayering	This enumeration controls how GoLayoutLayeredDigraph.AssignLayers assigns each node of the graph to a layer.
	GoLayoutLayeredDigraphPack	These enumerated values can be bitwise combined as values for the GoLayoutLayeredDigraph.PackOption property, which controls how much and what kinds of effort GoLayoutLayeredDigraph.StraightenAndPack makes.
	GoLayoutTreeAlignment	This enumeration specifies how to position a parent GoLayoutTreeNode relative to its children.
	GoLayoutTreeArrangement	This enumeration specifies how to position the resulting trees in the document.
	GoLayoutTreeCompaction	This enumeration specifies how closely packed the children of a node should be.
	GoLayoutTreePath	This enumeration specifies how to build a tree from the GoLayoutTreeNetwork.
	GoLayoutTreeSorting	This enumeration specifies whether to sort the children of a node, and in what order to position them.
	GoLayoutTreeStyle	This enumeration identifies the general style in which the nodes are laid out.
