Property	Gets the mapped property. (Inherited from IColumnMappingBase)
TableMapping	Gets the containing table mapping.
TypeMapping	Gets the type mapping for the column-like object. (Inherited from IColumnMappingBase)

Methods

AddRuntimeAnnotation(String, Object)	Adds a runtime annotation to this object. Throws if an annotation with the specified name already exists. (Inherited from IAnnotatable)
AnnotationsToDebugString(Int32)	Gets the debug string for all annotations declared on the object. (Inherited from IReadOnlyAnnotatable)
FindAnnotation(String)	Gets the annotation with the given name, returning null if it does not exist. (Inherited from IReadOnlyAnnotatable)
FindRuntimeAnnotation(String)	Gets the runtime annotation with the given name, returning null if it does not exist. (Inherited from IAnnotatable)
FindRuntimeAnnotationValue(String)	Gets the value of the runtime annotation with the given name, returning null if it does not exist. (Inherited from IAnnotatable)
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.
