Methods

AreIndexedBy(IReadOnlyList<IConventionProperty>, Boolean, IReadOnlyList<IConventionProperty>, Boolean)	Returns a value indicating whether the given properties are already covered by an existing index.
CreateIndex(IReadOnlyList<IConventionProperty>, Boolean, IConventionEntityTypeBuilder)	Creates an IConventionIndex.
ProcessEntityTypeBaseTypeChanged(IConventionEntityTypeBuilder, IConventionEntityType, IConventionEntityType, IConventionContext<IConventionEntityType>)	Called after the base type of an entity type changes.
ProcessForeignKeyAdded(IConventionForeignKeyBuilder, IConventionContext<IConventionForeignKeyBuilder>)	Called after a foreign key is added to the entity type.
ProcessForeignKeyAdded(IConventionRelationshipBuilder, IConventionContext<IConventionRelationshipBuilder>)	Called after a foreign key is added to the entity type.
ProcessForeignKeyPropertiesChanged(IConventionForeignKeyBuilder, IReadOnlyList<IConventionProperty>, IConventionKey, IConventionContext<IReadOnlyList<IConventionProperty>>)	Called after the foreign key properties or principal key are changed.
ProcessForeignKeyPropertiesChanged(IConventionRelationshipBuilder, IReadOnlyList<IConventionProperty>, IConventionKey, IConventionContext<IConventionRelationshipBuilder>)	Called after the foreign key properties or principal key are changed.
ProcessForeignKeyRemoved(IConventionEntityTypeBuilder, IConventionForeignKey, IConventionContext<IConventionForeignKey>)	Called after a foreign key is removed.
ProcessForeignKeyUniquenessChanged(IConventionForeignKeyBuilder, IConventionContext<Nullable<Boolean>>)	Called after the uniqueness for a foreign key is changed.
ProcessForeignKeyUniquenessChanged(IConventionRelationshipBuilder, IConventionContext<IConventionRelationshipBuilder>)	Called after the uniqueness for a foreign key is changed.
ProcessIndexAdded(IConventionIndexBuilder, IConventionContext<IConventionIndexBuilder>)	Called after an index is added to the entity type.
ProcessIndexRemoved(IConventionEntityTypeBuilder, IConventionIndex, IConventionContext<IConventionIndex>)	Called after an index is removed.
ProcessIndexUniquenessChanged(IConventionIndexBuilder, IConventionContext<IConventionIndexBuilder>)	Called after the uniqueness for an index is changed.
ProcessIndexUniquenessChanged(IConventionIndexBuilder, IConventionContext<Nullable<Boolean>>)	Called after the uniqueness for an index is changed.
ProcessKeyAdded(IConventionKeyBuilder, IConventionContext<IConventionKeyBuilder>)	Called after a key is added to the entity type.
ProcessKeyRemoved(IConventionEntityTypeBuilder, IConventionKey, IConventionContext<IConventionKey>)	Called after a key is removed from the entity type.
ProcessModelFinalized(IConventionModelBuilder, IConventionContext<IConventionModelBuilder>)	Called after a model is finalized.
ProcessModelFinalizing(IConventionModelBuilder, IConventionContext<IConventionModelBuilder>)	Called when a model is being finalized.
