Properties

	Name	Description
	Categories	Returns all categories. Never returns null.
	CategoryCount	Returns the number of categories in the object.
	DescriptiveCategoryLabel	Creates a delimited list of all category labels for this graph object.
	DocumentSchema	Gets the document-local schema from the owner of this graph.
	IsGroup	Gets whether this object is IsGroup. It looks for the GraphProperties.StyleForGroup.
	IsPseudo	Gets whether this object is Pseudo. It looks for the GraphProperties.IsPseudo.
	Item	Property that gets or sets a property value.
	Owner	Gets the Graph object that this object belongs to.
	Properties	Property that returns an enumeration of all annotations. The order of the enumeration is random.
	PropertyCount	Property that returns a number of all annotations.
	PropertyKeys	Property that returns an enumeration of all annotation keys. The order of the enumeration is random.
	PropertyValues	Property that returns an enumeration of all annotation values. The order of the enumeration is random.
	Visibility	Helper property to get/set visibility property of a GraphObject.

Methods

	Name	Description
	AddCategory	Adds a category to the object.
	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.
	ClearCategories	Remove all categories from this object.
	ClearValue(GraphProperty)	Removes the value of the specified property.
	ClearValue<T>(GraphProperty)	Clears the value of the specified property.
	CopyCategories	Copies any new categories from the given object, keeping existing categories.
	CopyProperties	Copies any new properties from the given object, keeping existing property values unchanged.
	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.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetMetaObject
	GetSchemaValue	Gets the schema-specific value of the property, if one exists.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetValue(String)	Gets the value of the specified property.
	GetValue(GraphProperty)	Gets the value of the specified annotation.
	GetValue<T>(String)	Gets the value of the specified property.
	GetValue<T>(GraphProperty)	Gets the value of the specified property.
	GetValue<T>(GraphProperty, Graph)	Gets the value of the specified property.
	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.
	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.
	GetValueAsString	Returns the given property as a string that uses the given culture.
	HasCategory(String)	Returns true if the object has the given category.
	HasCategory(GraphCategory)	Returns true if the object has the given category.
	HasCategory(IEnumerable<GraphCategory>)	Returns true if the object has any of the given categories.
	HasCategoryInSet	Determines whether the given set of categories applies to this object.
	HasLocalValue	Returns true if the specified property exists on this object with no category inheritance check.
	HasValue(String)	Find out whether the object has a value for the specified property.
	HasValue(GraphProperty)	Returns true if the specified annotation exists.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnCategoryChanged
	OnPropertyChanged(String)	Raises a PropertyChangd event for the named property.
	OnPropertyChanged(GraphProperty)	Raises a PropertyChangd event for the given GraphProperty.
	RemoveCategory	Removes the category of this object.
	SetValue(String, Object)	Adds an annotation, using the given key, type, and value.
	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.
	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.
