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 (i.e they should be replaced by database generated values when the entity is saved) or are permanent (i.e. the generated values should be saved to the database). (Inherited from ValueGenerator) |
