Constructors

Graph()

Constructs a Graph object.

Graph(SerializationInfo, StreamingContext)

Special constructor that is used for deserialization only.

Properties

AllGroups

Every group in the graph regardless of visibility or nesting

AllSchemas

Return a list of all unique known schemas.

Categories

Return all categories. Never returns null.

(Inherited from GraphObject)
CategoryCount

Return number of categories in the object.

(Inherited from GraphObject)
CommonPaths

A dictionary of the common paths that are replaced during serialization.

DescriptiveCategoryLabel

Creates a delimited list of all category labels for this graph object.

(Inherited from GraphObject)
DocumentSchema

Get The document schema of the Graph which contains all properties and categories discovered by serializer that were not already defined in a schema registered via AddSchema. Does not return null.

Groups

Get the collection of all top level groups

IsGroup

Get whether this object is is a group. It looks for the GraphCommonSchema.Group property on the object.

(Inherited from GraphObject)
IsPseudo

Get whether this object is Pseudo. It looks for the GraphProperties.IsPseudo

(Inherited from GraphObject)
Item[GraphProperty]

Property that gets or sets a property value.

(Inherited from GraphObject)
Links

Get the collection of links

Nodes

Get the collection of all nodes in the graph, including nodes that are groups.

OrphanNodes

Get all nodes that are not children of any GraphGroup

Owner

Get the Graph object that this object belongs to.

(Inherited from GraphObject)
Paths

CommonPaths found by the serializer during load which we will also use during save.

Properties

Property that returns an enumeration of all annotations. The order of the enumeration is random.

(Inherited from GraphObject)
PropertyCount

Property that returns an number of of all annotations.

(Inherited from GraphObject)
PropertyKeys

Property that returns an enumeration of all annotation keys. The order of the enumeration is random.

(Inherited from GraphObject)
PropertyValues

Property that returns an enumeration of all annotation values. The order of the enumeration is random.

(Inherited from GraphObject)
Styles

Get the collection of styles

Visibility

Helper property to get/set visibility property of a GraphObject

(Inherited from GraphObject)
VisibleLinks

Return the visible links (link.IsVisible == true) and whose source and target nodes are also visible and not inside any collapsed groups

VisibleNodes

Return the visible nodes (node.IsVisible == true)

VisibleOrphanNodes

Get all visible nodes that are not children of any GraphGroup

VisibleTopLevelGroups

Return the visible top level groups (node.IsVisible == true).

Methods

AddCategory(GraphCategory)

Add a category to the object

(Inherited from GraphObject)
AddSchema(GraphSchema)

Add a new schema to the Graph - once it's added, it cannot be removed again as nodes or links might be using categories or properties from the schema.

AsNode()

Converts the GraphObject to a GraphNode. If this is a GraphGroup, the inner node is returned. For types other than GraphNode/Group, null is returned.

(Inherited from GraphObject)
BeginUpdate(Object, String, UndoOption, Boolean)

Start a batch mode update on the Graph (which is more efficient). You must call the Complete() method on the returned GraphTransactionScope otherwise your changes will be rolled back. The usual pattern is to use this in a using block so that if an exception is thrown the changes are automatically rolled back.

BeginUpdate(Object, String, UndoOption)

Start a batch mode update on the Graph (which is more efficient). You must call the Complete() method on the returned GraphTransactionScope otherwise your changes will be rolled back.
