Properties

GeneratesStableValues

Gets a value indicating whether the values generated are stable. That is, the value will always be the same for a given property in a given entity, and does not depend on what other values may have been generated previously. For example, discriminator values generated for a TPH hierarchy are stable. Stable values will never be marked as unknown.

(Inherited from ValueGenerator)
GeneratesTemporaryValues

Gets a value indicating whether the values generated are temporary or permanent. This implementation always returns false, meaning the generated values will be saved to the database.
