The PrecedenceConstraint type exposes the following members.
|ConstrainedExecutable||Returns the name of a constrained container. This property is read-only.|
|CreationName||Returns the string used by the Integration Services runtime to create an instance of the PrecedenceConstraint object and add the object to the PrecedenceConstraints collection. This property is read-only.|
|Description||Gets or sets a description for the constraint.|
|EvalOp||Gets or sets the evaluation operations used by the precedence constraint.|
|EvaluatesTrue||Returns the Boolean value of the Value property. This property is read-only.|
|Expression||Gets or sets the expression that the precedence constraint uses if EvalOp is set to Expression, ExpressionAndConstraint, or ExpressionOrConstraint.|
|ID||Returns the GUID of the precedence constraint. This property is read-only.|
|LogicalAnd||Gets or sets a Boolean that indicates whether multiple constraints work together.|
|Name||Gets or sets the unique name of the precedence constraint.|
|PrecedenceExecutable||Returns the name of the precedence executable. This property is read-only.|
|Value||Gets or sets the constraint type of Success, Failure, or Completion.|
|Dispose||This method is inherited from the IDisposable.Dispose method, which is a generic mechanism to explicitly tell an object to perform cleanup.|
|Equals||Determines whether two object instances are equal. (Inherited from DtsObject.)|
|Finalize||(Inherited from Object.)|
|GetHashCode||Returns the hash code for this instance. (Inherited from DtsObject.)|
|GetType||(Inherited from Object.)|
|LoadFromXML||This method is not callable by your application code. To load a package containing precedence constraints that are saved as .xml, use the Application.LoadPackage method.|
|MemberwiseClone||(Inherited from Object.)|
|SaveToXML||This method is not callable by your application code. To save a package as .xml, use the Application.SaveToXml method.|
|ToString||(Inherited from Object.)|
|Disposed||Adds an event handler to listen to the Disposed event on the precedence constraint.|
You can specify the precedence and constrained executables that the precedence constraint connects, the expression and constraint that determine whether the constrained executable runs, and whether the precedence constraint works in concert with other precedence constraints.
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
