Methods

	Name	Description
	Equals	(Inherited from Object.)
	Finalize	(Inherited from Object.)
	GetAnnotationValue	Retrieves an annotation value for an EDM element. Returns null if no annotation with the given name exists for the given element.
	GetAnnotationValues	Retrieves a set of annotation values. For each requested value, returns null if no annotation with the given name exists for the given element.
	GetAttachedAnnotations	Retrieves the annotations that are directly attached to an element.
	GetDirectValueAnnotations	Gets annotations associated with an element.
	GetHashCode	(Inherited from Object.)
	GetType	(Inherited from Object.)
	MemberwiseClone	(Inherited from Object.)
	SetAnnotationValue	Sets an annotation value for an EDM element. If the value is null, no annotation is added and an existing annotation with the same name is removed.
	SetAnnotationValues	Sets a set of annotation values. If a supplied value is null, no annotation is added and an existing annotation with the same name is removed.
	ToString	(Inherited from Object.)

Remarks

An object representing transient annotations is in one of these states: 1) Null, if the element has no transient annotations. 2) An EdmAnnotation, if the element has exactly one annotation. 3) A list of EdmAnnotation, if the element has more than one annotation. If the speed of annotation lookup for elements with many annotations becomes a concern, another option including a dictionary is possible.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
