Properties

  Name Description
Public property Categories Returns all categories. Never returns null. (Inherited from GraphObject.)
Public property CategoryCount Returns the number of categories in the object. (Inherited from GraphObject.)
Public property Container The object that this metadata describes.
Public property DefaultValue Default value
Public property Description Description of this GraphProperty
Public property DescriptiveCategoryLabel Creates a delimited list of all category labels for this graph object. (Inherited from GraphObject.)
Public property DocumentSchema Gets the document-local schema from the owner of this graph. (Inherited from GraphObject.)
Public property Group For grouping this Property in a Property Grid.
Public property IsBrowsable Return true if the property is browsable
Public property IsGroup Gets whether this object is IsGroup. It looks for the GraphProperties.StyleForGroup. (Inherited from GraphObject.)
Public property IsPseudo Gets whether this object is Pseudo. It looks for the GraphProperties.IsPseudo. (Inherited from GraphObject.)
Public property IsRemovable Return true if the property is removable.
Public property IsSerializable Return true if the property is serializable
Public property IsSharable Return true if the property is sharable
Public property IsSubstitutable Return true if the property is serializable and Aliasing is allowed
Public property IsUndoable Return true if the property is undoable.
Public property IsWriteOnce Return true if the property is write once
Public property Item Property that gets or sets a property value. (Inherited from GraphObject.)
Public property Label Displayable label of this GraphProperty
Public property Options Flags that control how annotations of this metadata behaves.
Public property Owner Gets the Graph object that this object belongs to. (Inherited from GraphObject.)
Public property Properties Property that returns an enumeration of all annotations. The order of the enumeration is random. (Inherited from GraphObject.)
Public property PropertyCount Property that returns a number of all annotations. (Inherited from GraphObject.)
Public property PropertyKeys Property that returns an enumeration of all annotation keys. The order of the enumeration is random. (Inherited from GraphObject.)
Public property PropertyValues Property that returns an enumeration of all annotation values. The order of the enumeration is random. (Inherited from GraphObject.)
Public property Visibility Helper property to get/set visibility property of a GraphObject. (Inherited from GraphObject.)

Methods

  Name Description
Public method AddCategory Adds a category to the object. (Inherited from GraphObject.)
Public method 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.)
Public method ClearCategories Remove all categories from this object. (Inherited from GraphObject.)
Public method ClearValue(GraphProperty) Removes the value of the specified property. (Inherited from GraphObject.)
Public method Copy Make a copy of the graph metadata.
Public method CopyCategories Copies any new categories from the given object, keeping existing categories. (Inherited from GraphObject.)
Public method CopyProperties Copies any new properties from the given object, keeping existing property values unchanged. (Inherited from GraphObject.)
Public method Equals Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetMetaObject (Inherited from GraphObject.)
Protected method GetSchemaValue (Overrides GraphObject.GetSchemaValue(GraphProperty).)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method GetValue(String) Gets the value of the specified property. (Inherited from GraphObject.)
Public method GetValue(GraphProperty) Gets the value of the specified annotation. (Inherited from GraphObject.)
Public method GetValue<T>(GraphProperty, Graph) Gets the value of the specified property. (Inherited from GraphObject.)
Public method 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.)
Public 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. (Inherited from GraphObject.)
Public method GetValueAsString Returns the given property as a string that uses the given culture. (Inherited from GraphObject.)
Public method HasCategory(String) Returns true if the object has the given category. (Inherited from GraphObject.)
Public method HasCategory(GraphCategory) Returns true if the object has the given category. (Inherited from GraphObject.)
Public method HasCategory(IEnumerable<GraphCategory>) Returns true if the object has any of the given categories. (Inherited from GraphObject.)
Public method HasCategoryInSet Determines whether the given set of categories applies to this object. (Inherited from GraphObject.)
Public method HasLocalValue Returns true if the specified property exists on this object with no category inheritance check. (Inherited from GraphObject.)
Public method HasValue(String) Find out whether the object has a value for the specified property. (Inherited from GraphObject.)
Public method HasValue(GraphProperty) Returns true if the specified annotation exists. (Inherited from GraphObject.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Protected method OnCategoryChanged (Inherited from GraphObject.)
Public method OnPropertyChanged(String) Raises a PropertyChangd event for the named property. (Inherited from GraphObject.)
Public method OnPropertyChanged(GraphProperty) Raises a PropertyChangd event for the given GraphProperty. (Inherited from GraphObject.)
Public method RemoveCategory Removes the category of this object. (Inherited from GraphObject.)
Public method SetValue(String, Object) Adds an annotation, using the given key, type, and value. (Inherited from GraphObject.)
Public method 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.)
Public method ToString Returns a string that represents the current object. (Inherited from Object.)
Protected method 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.)
