RuleWriteAttribute 类

定义

指示由应用此属性 (attribute) 的方法或属性 (property) 写入属性 (property) 或字段。Indicates that a property or field is written by the method or property that this attribute is applied to. 规则引擎使用此信息确定规则之间的依赖性。This information is used by the rules engine to determine dependencies between rules. 此类不能被继承。This class cannot be inherited.

属性

注解

此属性用于支持正向链接模型,该模型将导致基于对字段和属性的更改而重新计算规则。This attribute is used to support a forward chaining model that causes the re-evaluation of rules based on changes to fields and properties. RuleReadAttributeRuleWriteAttribute 指示由应用属性 (Attribute) 的属性 (Property) 或方法读取或写入的属性 (Property)。The RuleReadAttribute and RuleWriteAttribute indicate the properties read or written by the property or method the attribute is applied to. RuleInvokeAttributes用于指示此属性或方法使用其他方法, 这些方法还必须检查依赖关系。RuleInvokeAttributes are used to indicate that this property or method uses other methods, which must also be checked for dependencies.

构造函数

属性

Path

获取到属性的目标的路径。Gets the path to the target of the attribute.

(继承自 RuleReadWriteAttribute)
Target

获取确定如何使用路径查找目标的 RuleAttributeTarget 枚举值。Gets the RuleAttributeTarget enumeration value that determines how to use path to find target.

(继承自 RuleReadWriteAttribute)
TypeId

在派生类中实现时,获取此 Attribute 的唯一标识符。When implemented in a derived class, gets a unique identifier for this Attribute.

(继承自 Attribute)

方法

Equals(Object)

返回一个值,该值指示此实例是否与指定的对象相等。Returns a value that indicates whether this instance is equal to a specified object.

(继承自 Attribute)
GetHashCode()

返回此实例的哈希代码。Returns the hash code for this instance.

(继承自 Attribute)
GetType()

获取当前实例的 TypeGets the Type of the current instance.

(继承自 Object)
IsDefaultAttribute()

在派生类中重写时,指示此实例的值是否是派生类的默认值。When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(继承自 Attribute)
Match(Object)

当在派生类中重写时,返回一个指示此实例是否等于指定对象的值。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(继承自 Attribute)
MemberwiseClone()

创建当前 Object 的浅表副本。Creates a shallow copy of the current Object.

(继承自 Object)
ToString()

返回一个表示当前对象的 string。Returns a string that represents the current object.

(继承自 Object)

显式接口实现

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

将一组名称映射为对应的一组调度标识符。Maps a set of names to a corresponding set of dispatch identifiers.

(继承自 Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

检索对象的类型信息,然后可以使用该信息获取接口的类型信息。Retrieves the type information for an object, which can be used to get the type information for an interface.

(继承自 Attribute)
_Attribute.GetTypeInfoCount(UInt32)

检索对象提供的类型信息接口的数量(0 或 1)。Retrieves the number of type information interfaces that an object provides (either 0 or 1).

(继承自 Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)
