RelationshipEdge Class

Class which represents a relationship between two entities in the entity graph. The RelationshipType defines how the startVertex is related to the endVertex. It also implies how the endVertex is related to the startVertex, as the relationship has no direction: it's a relationship between the startVertex and the endVertex.

The RelationshipEdge type exposes the following members.

Constructors

	Name	Description
	RelationshipEdge(EntityDefinition, EntityDefinition)	Initializes a new instance of the RelationshipEdge class.
	RelationshipEdge(EntityDefinition, EntityDefinition, EntityRelationshipType)	Initializes a new instance of the RelationshipEdge class.
	RelationshipEdge(EntityDefinition, EntityDefinition, EntityRelationshipType, String, String)	Initializes a new instance of the RelationshipEdge class.

Properties

	Name	Description
	EndEntityNavigator	Gets / sets the field name mapped onto this relationship in the endEntity.
	EndEntityNavigatorValidator	Gets the end entity navigator validator.
	EndNavigatorIsHidden	Returns true if the end navigator is empty/hidden
	EndVertex	Gets the end vertex of the edge. (Inherited from EdgeTVertex.)
	Error	Gets an error message indicating what is wrong with this object.
	FullDescription	Gets the full description of this relationship, to be used in textual representations of the relationhip in for example trees.
	FullDescriptionReverse	Gets the full reverse description, so if FullDescription returns startentity 1:n endentity, this property returns endentity m:1 startentity
	IsDirected	Gets a value indicating whether this edge is directed. If true, the edge is directed from startVertex to endVertex and is seen as an edge only between startVertex and endVertex, not between endVertex and startVertex. If false, this edge isn't considered a directed edge and is seen as an edge between startVertex and endVertex and also between endVertex and startVertex. (Inherited from EdgeTVertex.)
	Item	Gets the String with the specified column name.
	ModelOnly	Gets or sets a value indicating whether this relationship is a 'model only' (true) relationship or a full relationship (false). Full relationships require a foreign key constraint in the relational model data.
	RelationshipType	Gets / sets the type of the relationship.
	StartEntityNavigator	Gets / sets the field name mapped onto this relationship in the startEntity.
	StartEntityNavigatorValidator	Gets the start entity navigator validator.
	StartNavigatorIsHidden	Returns true if the start navigator is empty/hidden
	StartVertex	Gets the start vertex of the edge. (Inherited from EdgeTVertex.)
	UniqueAssociationName	Returns a unique association name. The name can be used using code generation if the whole model is consumed in 1 go to refer to associations. Format: StartvertexFullName_EndVertexFullName_StartNavigator_EndNavigator. If both navigators are empty, Guid(N) is used instead of navigatornames, and the format becomes StartvertexFullName_EndVertexFullName_Guid.

Methods

	Name	Description
	_member_ValueChangedTValue	Handles the ValueChanged event of a member variable which is a commandifiedmember.
	CompareTo	Compares the current instance with another object of the same type and returns an integer that indicates whether the current instance precedes, follows, or occurs in the same position in the sort order as the other object.
	DetermineIfEntityIsEqualToEndPoints	Determines if the entity specified is equal to or a subtype of the start entity and end entity.
	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.)
	GetCollectionNavigators	Gets the collection navigators (0, 1 or 2) contained by this relationship, if applicable. A 1:1 relationship has 0 collection navigators, a 1:n relationship 1 and a m:n relationship 2. Navigators which are empty are ignored, as they're not there.
	GetEndNavigatorAsObject	Gets the end navigator string as Navigator object.
	GetFullDescription	Gets the full description of this relationship.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetSingleElementNavigators	Gets the single element navigators (0, 1 or 2) contained by this relationship, if applicable. A 1:1 relationship has 2 single element navigators, a 1:n relationship 1 and a m:n relationship 0. Navigators which are empty are ignored, as they're not there.
	GetStartNavigatorAsObject	Gets the start navigator string as Navigator object.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MarkElementAsChanged	Marks the element as changed.
	MarkElementAsRemoved	Marks this field as removed. This routine will raise INotifyAsRemoved.ElementRemoved
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnRelationshipTypeChanged	Called when the relationtype was changed. Called from command.
	OnStartEntityIsPkSideChanged	Called when the StartEntityIsPkSide flag changed.
	SerializeOutputSettingValues	Serializes the output setting values for the start and end navigator
	SerializeToWriter	Serializes the data in this class to the serializer passed in
	ToggleModelOnlyFlag	Toggles the model only flag on this, if the relationship is a normal relationship as the model-only-ness of an indirect relationship is readonly (as it's determined based on the modelonly flag of the contained relationships in the indirect relationship).
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	ToStringReverse	As ToString() but now the description is from the point of view of the end entity.
	Validate	Validates this instance.

Events

	Name	Description
	HasBeenChanged	Raised when the implementing element has been changed
	HasBeenRemoved	Raised when the implementing element has been removed from its container
	RelationEdgeChanged	Event which is raised when the definition of this relationship edge has been changed. What has changed is enclosed inside the event args.
