A wrapper on nodes that have IsGroup=true. They do not have a separate identity; they use the identity of the node that they wrap.

The GraphGroup type exposes the following members.

Properties

	Name	Description
	Categories	Returns all categories. Never returns null. (Inherited from GraphObject.)
	CategoryCount	Returns the number of categories in the object. (Inherited from GraphObject.)
	ChildGroups	A collection of child GraphGroups. A child group is one that is linked to a parent group via an IsContainment link. This collection is automatically maintained as nodes are added and removed from the graph and as IsGroup properties are changed and as containment links are added or removed.
	ChildNodes	A collection of child nodes (excluding nodes that have IsGroup set to true). A child node is one that is linked to a parent group via an IsContainment link. This collection is automatically maintained as nodes are added and removed from the graph and as IsGroup properties are changed and as containment links are added or removed.
	ContainmentLinks	The containment links that are contained within this group.
	ContentVisibility	Get whether the content inside this node is visible or not.
	DescriptiveCategoryLabel	Creates a delimited list of all category labels for this graph object. (Inherited from GraphObject.)
	DocumentSchema	Gets the document-local schema from the owner of this graph. (Inherited from GraphObject.)
	GroupNode
	Id
	IsEmpty	Find out whether the group contains any child nodes or groups.
	IsExpanded	Get whether this node is expanded.
	IsGroup	Gets whether this object is IsGroup. It looks for the GraphProperties.StyleForGroup. (Inherited from GraphObject.)
	IsPseudo	Gets whether this object is Pseudo. It looks for the GraphProperties.IsPseudo. (Inherited from GraphObject.)
	Item	Property that gets or sets a property value. (Inherited from GraphObject.)
	Label
	Owner	Gets the Graph object that this object belongs to. (Inherited from GraphObject.)
	Parents	The parents of this group.
	Properties	Property that returns an enumeration of all annotations. The order of the enumeration is random. (Inherited from GraphObject.)
	PropertyCount	Property that returns a number 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.)
	Visibility	Helper property to get/set visibility property of a GraphObject. (Inherited from GraphObject.)

Methods

	Name	Description
	AddCategory	Adds a category to the object. (Inherited from GraphObject.)
	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.)
	ClearCategories	Remove all categories from this object. (Inherited from GraphObject.)
	ClearValue(GraphProperty)	Removes the value of the specified property. (Inherited from GraphObject.)
	CopyCategories	Copies any new categories from the given object, keeping existing categories. (Inherited from GraphObject.)
	CopyProperties	Copies any new properties from the given object, keeping existing property values unchanged. (Inherited from GraphObject.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetAncestors	Returns all the parent ancestors of this group, excluding this group.
	GetDescendantGroups	Returns all descendant groups that are contained by this group hierarchy, including this group.
	GetDescendants	Returns all descendant nodes that are contained by this group hierarchy.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetMetaObject	(Inherited from GraphObject.)
	GetSchemaValue	Gets the schema-specific value of the property, if one exists. (Inherited from GraphObject.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetValue(String)	Gets the value of the specified property. (Inherited from GraphObject.)
	GetValue(GraphProperty)	Gets the value of the specified annotation. (Inherited from GraphObject.)
	GetValue<T>(GraphProperty, Graph)	Gets the value of the specified property. (Inherited from GraphObject.)
	GetValue<T>(GraphProperty, T)	Gets the value of the specified annotation. If property is not set, we return the default value that the caller passed to this method. (Inherited from GraphObject.)
	GetValue<T>(GraphProperty, Graph, GraphCategory%)	Gets the value of the specified property, and also returns the category that this property value was inherited from, if any. (Inherited from GraphObject.)
	GetValueAsString	Returns the given property as a string that uses the given culture. (Inherited from GraphObject.)
	HasCategory(String)	Returns true if the object has the given category. (Inherited from GraphObject.)
	HasCategory(GraphCategory)	Returns true if the object has the given category. (Inherited from GraphObject.)
	HasCategory(IEnumerable<GraphCategory>)	Returns true if the object has any of the given categories. (Inherited from GraphObject.)
	HasCategoryInSet	Determines whether the given set of categories applies to this object. (Inherited from GraphObject.)
	HasLocalValue	Returns true if the specified property exists on this object with no category inheritance check. (Inherited from GraphObject.)
	HasValue(String)	Find out whether the object has a value for the specified property. (Inherited from GraphObject.)
	HasValue(GraphProperty)	Returns true if the specified annotation exists. (Inherited from GraphObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnCategoryChanged	Raises the property changed events for both the node and the group. (Overrides GraphObject.OnCategoryChanged(GraphCategory, GraphCategoryChangeType).)
	OnPropertyChanged(String)	Raises the property changed events for both the node and the group. (Overrides GraphObject.OnPropertyChanged(String).)
	OnPropertyChanged(GraphProperty)	Raises a PropertyChangd event for the given GraphProperty. (Inherited from GraphObject.)
	RemoveCategory	Removes the category of this object. (Inherited from GraphObject.)
	SetValue(String, Object)	Adds an annotation, using the given key, type, and value. (Inherited from GraphObject.)
	SetValue<T>(GraphProperty, T)	Sets the value of the given property. If the property already exists, its value is overwritten unless the annotation flags prevent otherwise. (Inherited from GraphObject.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	WrapGraphObject	Modifies the current graph object to share the same property and categories as the given graph object. The wrapper and wrappee graph objects will always have identical sets of properties and categories. (Inherited from GraphObject.)
