Methods

  Name Description
Public method Equals (Inherited from Object.)
Protected method Finalize (Inherited from Object.)
Public method GetAnnotationValue Retrieves an annotation value for an EDM element. Returns null if no annotation with the given name exists for the given element.
Public method 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.
Protected method GetAttachedAnnotations Retrieves the annotations that are directly attached to an element.
Public method GetDirectValueAnnotations Gets annotations associated with an element.
Public method GetHashCode (Inherited from Object.)
Public method GetType (Inherited from Object.)
Protected method MemberwiseClone (Inherited from Object.)
Public method 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.
Public method 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.
Public method 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.
