Remarks

This attribute is used to support a forward chaining model that causes the re-evaluation of rules based on state change. The RuleReadAttribute, RuleInvokeAttribute, and RuleWriteAttribute classes each indicate the properties used to read a condition, write an action, and invoke a method. These attributes enable the workflow to only reevaluate rules that change the final output.

Constructors

RuleReadAttribute(String, RuleAttributeTarget)	Initializes a new instance of the RuleReadAttribute class.
RuleReadAttribute(String)	Initializes a new instance of the RuleReadAttribute class.

Properties

Path	Gets the path to the target of the attribute. (Inherited from RuleReadWriteAttribute)
Target	Gets the RuleAttributeTarget enumeration value that determines how to use path to find target. (Inherited from RuleReadWriteAttribute)
TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)

Methods

Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute)
GetHashCode()	Returns the hash code for this instance. (Inherited from Attribute)
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(Object)	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)

Explicit Interface Implementations

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)	Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute)
_Attribute.GetTypeInfoCount(UInt32)	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)	Provides access to properties and methods exposed by an object. (Inherited from Attribute)
