Public Overridable Function GetOrAdd (property As IProperty, entityType As IEntityType, factory As Func(Of IProperty, IEntityType, ValueGenerator)) As ValueGenerator

参数

property: IProperty

要为其获取值生成器的属性。

entityType: IEntityType

值生成器将用于的实体类型。对派生实体类型上的继承属性调用时，此实体类型可能与声明的实体类型不同 property

factory: Func<IProperty,IEntityType,ValueGenerator>

如果缓存中不存在值生成器，则用于创建新值生成器的工厂。

ValueGenerator

现有或新创建的值生成器。
