Properties

Columns	The ordered list of columns that make up the primary key.
IsReadOnly	Indicates whether the current object is read-only. (Inherited from AnnotatableBase)
Item[String]	Gets the value annotation with the given name, returning null if it does not exist. (Inherited from Annotatable)
Name	The name of the primary key.
Table	The table on which the primary key is defined.

Methods

AddAnnotation(String, Annotation)	Adds an annotation to this object. Throws if an annotation with the specified name already exists. (Inherited from Annotatable)
AddAnnotation(String, Object)	Adds an annotation to this object. Throws if an annotation with the specified name already exists. (Inherited from Annotatable)
AddAnnotations(IEnumerable<IAnnotation>)	Adds annotations to this object. (Inherited from AnnotatableBase)
AddAnnotations(IReadOnlyDictionary<String,Object>)	Adds annotations to this object. (Inherited from AnnotatableBase)
AddRuntimeAnnotation(String, Annotation)	Adds a runtime annotation to this object. Throws if an annotation with the specified name already exists. (Inherited from AnnotatableBase)
AddRuntimeAnnotation(String, Object)	Adds a runtime annotation to this object. Throws if an annotation with the specified name already exists. (Inherited from AnnotatableBase)
AddRuntimeAnnotations(IEnumerable<Annotation>)	Adds runtime annotations to this object. (Inherited from AnnotatableBase)
AddRuntimeAnnotations(IReadOnlyDictionary<String,Object>)	Adds runtime annotations to this object. (Inherited from AnnotatableBase)
CreateAnnotation(String, Object)	Creates a new annotation. (Inherited from Annotatable)
CreateRuntimeAnnotation(String, Object)	Creates a new runtime annotation. (Inherited from AnnotatableBase)
EnsureMutable()	Throws if the model is read-only. (Inherited from Annotatable)
EnsureReadOnly()	Throws if the model is not read-only. (Inherited from Annotatable)
FindAnnotation(String)	Gets the annotation with the given name, returning null if it does not exist. (Inherited from Annotatable)
FindRuntimeAnnotation(String)	Gets the runtime annotation with the given name, returning null if it does not exist. (Inherited from AnnotatableBase)
GetAnnotation(String)	Gets the annotation with the given name, throwing if it does not exist. (Inherited from AnnotatableBase)
GetAnnotations()	Gets all annotations on the current object. (Inherited from Annotatable)
GetOrAddAnnotation(String, Object)	Adds an annotation to this object or returns the existing annotation if one with the specified name already exists. (Inherited from Annotatable)
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 AnnotatableBase)
GetRuntimeAnnotations()	Gets all runtime annotations on the current object. (Inherited from AnnotatableBase)
OnAnnotationSet(String, Annotation, Annotation)	Called when an annotation was set or removed. (Inherited from Annotatable)
RemoveAnnotation(String)	Removes the given annotation from this object. (Inherited from Annotatable)
RemoveRuntimeAnnotation(String)	Removes the given runtime annotation from this object. (Inherited from AnnotatableBase)
SetAnnotation(String, Annotation, Annotation)	Sets the annotation stored under the given key. Overwrites the existing annotation if an annotation with the specified name already exists. (Inherited from Annotatable)
SetAnnotation(String, Annotation)	Sets the annotation stored under the given key. Overwrites the existing annotation if an annotation with the specified name already exists. (Inherited from Annotatable)
SetAnnotation(String, Object)	Sets the annotation stored under the given key. Overwrites the existing annotation if an annotation with the specified name already exists. (Inherited from Annotatable)
SetRuntimeAnnotation(String, Annotation, Annotation)	Sets the runtime annotation stored under the given key. Overwrites the existing annotation if an annotation with the specified name already exists. (Inherited from AnnotatableBase)
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 AnnotatableBase)
ToString()	Returns a string that represents the current object.

Explicit Interface Implementations
