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.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 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
