Represents the addition of a RuleCondition to a workflow during dynamic update. This class cannot be inherited.

Represents the addition of a RuleSet during dynamic update. This class cannot be inherited.

Represents the removal of a RuleCondition from a workflow during dynamic update. This class cannot be inherited.

Represents the removal of a RuleSet during dynamic update. This class cannot be inherited.

Defines a condition with an associated set of actions to perform.

Represents an abstract class that defines an action to be executed if the associated Condition evaluates to true, for ThenActions, or false, for ElseActions. This class must be inherited.

Contains the name, instance ID, and condition result of a rule that has been evaluated.

Stores the fields and properties read by a condition or written to by an action.

Represents the base class for custom Rule attributes.

Base type for RuleExpressionCondition and any custom conditions created by users.

Represents an abstract base class from which all dynamic update notifications of changes to RuleConditions must be derived.

Contains a collection of RuleCondition classes defined on the workflow. This class cannot be inherited.

Represents a RuleCondition in the conditions collection and enables you to programmatically evaluate the condition.

Represents the root of the .rules files and contains all the RuleSets and RuleConditions associated with a workflow. This class cannot be inherited.

Used to perform RuleSet evaluation.

Represents the base class for all exceptions caused by rule evaluation issues.

The exception that is thrown when attempting to apply an operator to incompatible operands when you evaluate a rule.

Represents the base class for all exceptions caused by evaluation or validation of rules.

Stores state information while executing RuleCondition or RuleAction classes.

Defines the condition definition behind a RuleConditionReference. This class cannot be inherited.

An instance of this class is returned by the Validate(RuleValidation, Boolean) method of an IRuleExpression expression.

Abstract class that is the base for classes representing the result of custom expressions based on the IRuleExpression interface.

Propagates the current behavior in the expression to child nodes. This class cannot be inherited.

Causes the RuleSet to stop executing and returns control back to the calling method.

Indicates that a method is invoked by a condition. This class cannot be inherited.

Represents the literal result of a custom expression written using IRuleExpression.

Builds the path of a field or property.

Indicates that a property is read by a Rule. This class cannot be inherited.

Represents the base class for the RuleReadAttribute and RuleWriteAttribute classes.

Contains a collection of Rule classes along with the semantics for forward-chaining execution of those rules. A RuleSet can be executed directly in code or using the PolicyActivity activity.

Represents an abstract base class from which all dynamic update notifications of changes to a RuleSet must be derived. This class cannot be inherited.

Contains a collection of RuleSet classes defined in a workflow.

Holds the name of a RuleSet in the RuleSetCollection on the workflow. This class cannot be inherited.

Represents the exception thrown when processing cannot continue because a rule set cannot be validated.

Specifies a property or field to update or a method to run using the CodeDom types.

Indicates that a rule is updating a variable, in order to cause reevaluation of affected rules.

Validates expression conditions.

Indicates that a property or field is written by the method or property that this attribute is applied to. This information is used by the rules engine to determine dependencies between rules. This class cannot be inherited.

Represents the change to a RuleSet for dynamic updates. This class cannot be inherited.

Represents the change to a RuleSet for dynamic updates. This class cannot be inherited.

Represents the base class from which custom expression writers must derive to write custom expressions.

Specifies whether the path in a RuleReadAttribute or RuleWriteAttribute is for a method parameter, or this.

Specifies the forward chaining behavior of the RuleSet.

Specifies whether a Rule can be reevaluated.
