Constructors
| ValueExpressionAttributeBase | Creates a new ValueExpressionAttributeBase |
Properties
| Cached | Gets or sets value that determines if value should be cached after first evaluation. Defaults to false. |
| EvaluationOrder | Gets or sets the numeric evaluation order for this expression. Defaults to zero. |
| Expression | Gets C# expression that will evaluate to the desired value. |
| TypeId | When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute) |
| TypeRegistry | Gets or sets any TypeRegistry to use if the attribute Expression needs to be pre-parsed. |
Methods
| Equals | Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetExpressionUpdateValue | Gets the modeled property based value used to update the Expression. |
| GetHashCode | Returns the hash code for this instance. (Inherited from Attribute) |
| GetPropertyUpdateValue | Gets the Expression based value used to update a modeled property. |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| IsDefaultAttribute | When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute) |
| Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
