GraphLink Class

Return all categories. Never returns null.

Return number of categories in the object.

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

Get the document local schema from the Owner of this graph.

Get the optional Index of this link. Default is zero. This index can be specified when you create a link, providing different index values makes it possible to create multiple links between the same source and target nodes. To get multilinks the index only needs to be unique for the same source and target nodes.

Return true if the source of the link is a group and the target of this link is a child of that group and this link has IsContainment=true.

Get whether this link is a Containment link or not (has the property IsContainment=true).

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

A link is "visible" when it is visible and its source and target nodes are visible as well.

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

Property that gets or sets a property value.

Displayable label for the link

Get the Graph object that this object belongs to.

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

Property that returns an number of of all annotations.

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

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

The Link source

The Link target

Helper property to get/set visibility property of a GraphObject

Add a category to the object

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.

Remove all categories from this object.

Removes the value of the specified property

Clear the value of the specified property.

Copy any new categories from the given object, keeping existing categories.

Copy any new properties from the given object, keeping existing property values unchanged.

Finds the links that match the acceptLink predicate. They are found by doing a breadth first search along links matching the traverseLink predicate, in the Source or Target direction designated by the searchDirection.

Return first matching leaf category that has the given category in its heirarchy.

Return first matching leaf category that has the given category in its heirarchy.

Gets the schema specific value of the property if one exists.

Gets the value of the specified annotation.

Gets the value of the specified property.

Gets the value of the specified property.

Gets the value of the specified property.

Gets the value of the specified property, and also return the category that this property value was inherited from if any.

Gets the value of the specified annotation. if property is not set we reutnr the default value that the caller pass to this method

Gets the value of the specified property.

Returns the given property as a string using the given culture.

Return true if the object has the given category.

Return true if the object has any of the given categories.

Return true if the object has the given category.

Determines if the given set of categories applies to this object.

Return true if the specified property exists on this object with no cateogry inheritance check.

Return true if the specified annotation exists.

Find out if the object has a value for the specified property.

Override that notifies the GraphGroupCollection any time a GraphCategory has changed on this link Notify the GraphGroupCollection any time a GraphCategory has changed on this link because this may affect the IsContainment behavior of this link which affects the structure of the GraphGroup hierarchy.

Raise a PropertyChangd event for the given GraphProperty

Raise a PropertyChangd event for the named property

Remove this link from the graph

Remove the category of this object

Add an annotation using the given key, type and value

Sets the value of the given property. If the proeprty already exists, its value is overwritten unless the annotation flags prevent otherwise.

A more human friendly default string representation of a Link object

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.

Returns the label of an object or the id if the label is null. Should be used for tracing Microsoft.VisualStudio.Diagnostics.PerformanceProvider.DebugTrace.IDebugTracer
