Gets the debug string for all annotations declared on the object. (Inherited from IReadOnlyAnnotatable) |
FindAnnotation(String) |
Gets the annotation with the given name, returning |
FindRuntimeAnnotation(String) |
Gets the runtime annotation with the given name, returning |
FindRuntimeAnnotationValue(String) |
Gets the value of the runtime annotation with the given name, returning |
GetAnnotation(String) |
Gets the annotation with the given name, throwing if it does not exist. (Inherited from IReadOnlyAnnotatable) |
GetAnnotations() |
Gets all annotations on the current object. (Inherited from IReadOnlyAnnotatable) |
GetOrAddRuntimeAnnotationValue<TValue,TArg>(String, Func<TArg,TValue>, TArg) |
Gets the value of the runtime annotation with the given name, adding it if one does not exist. (Inherited from IAnnotatable) |
GetRuntimeAnnotations() |
Gets all the runtime annotations on the current object. (Inherited from IAnnotatable) |
RemoveRuntimeAnnotation(String) |
Removes the given runtime annotation from this object. (Inherited from IAnnotatable) |
SetRuntimeAnnotation(String, Object) |
Sets the runtime annotation stored under the given key. Overwrites the existing annotation if an annotation with the specified name already exists. (Inherited from IAnnotatable) |
ToDebugString(MetadataDebugStringOptions, Int32) |
Creates a human-readable representation of the given metadata. Warning: Do not rely on the format of the returned string. It is designed for debugging only and may change arbitrarily between releases. |
