IMutableKey Interface

Definition

Namespace:

Microsoft.EntityFrameworkCore.Metadata

Assembly:

Microsoft.EntityFrameworkCore.dll

Package:

Microsoft.EntityFrameworkCore v9.0.0

Source:

IMutableKey.cs

Represents a primary or alternate key on an entity.

public interface IMutableKey : Microsoft.EntityFrameworkCore.Metadata.IMutableAnnotatable, Microsoft.EntityFrameworkCore.Metadata.IReadOnlyKey

type IMutableKey = interface
    interface IReadOnlyKey
    interface IReadOnlyAnnotatable
    interface IMutableAnnotatable

Public Interface IMutableKey
Implements IMutableAnnotatable, IReadOnlyKey

Implements

IMutableAnnotatable IReadOnlyAnnotatable IReadOnlyKey

Remarks

This interface is used during model creation and allows the metadata to be modified. Once the model is built, IKey represents a read-only view of the same metadata.

See Modeling entity types and relationships for more information and examples.

Properties

DeclaringEntityType	Gets the entity type the key is defined on. This may be different from the type that Properties are defined on when the key is defined a derived type in an inheritance hierarchy (since the properties may be defined on a base type).
Item[String]	Gets the value of the annotation with the given name, returning null if it does not exist. (Inherited from IReadOnlyAnnotatable)
Properties	Gets the properties that make up the key.

Methods

AddAnnotation(String, Object)	Adds an annotation to this object. Throws if an annotation with the specified name already exists. (Inherited from IMutableAnnotatable)
AddAnnotations(IEnumerable<IAnnotation>)	Adds annotations to an object. (Inherited from IMutableAnnotatable)
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)
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)
GetReferencingForeignKeys()	Gets all foreign keys that target a given primary or alternate key.
IsPrimaryKey()	Returns a value indicating whether the key is the primary key. (Inherited from IReadOnlyKey)
RemoveAnnotation(String)	Removes the given annotation from this object. (Inherited from IMutableAnnotatable)
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 IMutableAnnotatable)
SetOrRemoveAnnotation(String, Object)	Sets the annotation stored under the given name. Overwrites the existing annotation if an annotation with the specified name already exists. Removes the existing annotation if null is supplied. (Inherited from IMutableAnnotatable)
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. (Inherited from IReadOnlyKey)

Extension Methods

FindSharedObjectRootKey(IMutableKey, StoreObjectIdentifier)	Finds the first IMutableKey that is mapped to the same constraint in a shared table-like object. This method is typically used by database providers (and other extensions). It is generally not used in application code.
FindSharedObjectRootKey(IReadOnlyKey, StoreObjectIdentifier)	Finds the first IKey that is mapped to the same constraint in a shared table-like object. This method is typically used by database providers (and other extensions). It is generally not used in application code.
GetDefaultName(IReadOnlyKey, StoreObjectIdentifier)	Returns the default key constraint name that would be used for this key for a particular table.
GetDefaultName(IReadOnlyKey)	Returns the default key constraint name that would be used for this key.
GetName(IReadOnlyKey, StoreObjectIdentifier)	Returns the key constraint name for this key for a particular table.
GetName(IReadOnlyKey)	Returns the key constraint name for this key.
SetName(IMutableKey, String)	Sets the key constraint name for this key.
GetFillFactor(IReadOnlyKey, StoreObjectIdentifier)	Returns the fill factor that the key uses.
GetFillFactor(IReadOnlyKey)	Returns the fill factor that the key uses.
IsClustered(IReadOnlyKey, StoreObjectIdentifier)	Returns a value indicating whether the key is clustered.
IsClustered(IReadOnlyKey)	Returns a value indicating whether the key is clustered.
SetFillFactor(IMutableKey, Nullable<Int32>)	Sets a value for fill factor the key uses.
SetIsClustered(IMutableKey, Nullable<Boolean>)	Sets a value indicating whether the key is clustered.
