Methods

FindSharedObjectRootIndex(IConventionIndex, in StoreObjectIdentifier)

Finds the first Microsoft.EntityFrameworkCore.Metadata.IConventionIndex that is mapped to the same index 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.

public static IConventionIndex FindSharedObjectRootIndex(this IConventionIndex index, in StoreObjectIdentifier storeObject)

Parameters

index IConventionIndex

The index.

storeObject StoreObjectIdentifier

The identifier of the containing store object.

Returns

IConventionIndex

The index found, or null if none was found.

FindSharedObjectRootIndex(IIndex, in StoreObjectIdentifier)

Finds the first Microsoft.EntityFrameworkCore.Metadata.IIndex that is mapped to the same index 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.

public static IIndex FindSharedObjectRootIndex(this IIndex index, in StoreObjectIdentifier storeObject)

Parameters

index IIndex

The index.

storeObject StoreObjectIdentifier

The identifier of the containing store object.

Returns

IIndex

The index found, or null if none was found.

FindSharedObjectRootIndex(IMutableIndex, in StoreObjectIdentifier)

Finds the first Microsoft.EntityFrameworkCore.Metadata.IMutableIndex that is mapped to the same index 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.

public static IMutableIndex FindSharedObjectRootIndex(this IMutableIndex index, in StoreObjectIdentifier storeObject)

Parameters

index IMutableIndex

The index.

storeObject StoreObjectIdentifier

The identifier of the containing store object.
