PrecedenceConstraint PrecedenceConstraint PrecedenceConstraint PrecedenceConstraint Class

Definition

Specifies the properties for configuring a precedence constraint between two containers. This class cannot be inherited.

Remarks

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.

Properties

ConstrainedExecutable ConstrainedExecutable ConstrainedExecutable ConstrainedExecutable

Gets the name of a constrained container. This property is read-only.

CreationName CreationName CreationName CreationName

Gets 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 Description Description Description

Gets or sets a description for the constraint.

EvalOp EvalOp EvalOp EvalOp

Gets or sets the evaluation operations used by the precedence constraint.

EvaluatesTrue EvaluatesTrue EvaluatesTrue EvaluatesTrue

Gets a value that indicates whether the specified Value property evaluates to true. This property is read-only.

Expression Expression Expression Expression

Gets or sets the expression that the precedence constraint uses if EvalOp is set to Expression, ExpressionAndConstraint, or ExpressionOrConstraint.

ID ID ID ID

Gets the GUID of the precedence constraint. This property is read-only.

LogicalAnd LogicalAnd LogicalAnd LogicalAnd

Gets or sets a Boolean value that indicates whether multiple constraints work together.

Name Name Name Name

Gets or sets the unique name of the precedence constraint.

Parent Parent Parent Parent

Gets the parent container of the PrecedenceConstraint.

PrecedenceExecutable PrecedenceExecutable PrecedenceExecutable PrecedenceExecutable

Gets the name of the precedence executable. This property is read-only.

Site Site Site Site

Gets or sets the site of the precedence constraint.

Value Value Value Value

Gets or sets the constraint type of Success, Failure, or Completion.

Methods

Dispose() Dispose() Dispose() Dispose()

This method is inherited from the IDisposable.Dispose method, which is a generic mechanism to explicitly tell an object to perform cleanup.

Equals(Object) Equals(Object) Equals(Object) Equals(Object)

Determines whether two object instances are equal.

(Inherited from DtsObject)
GetHashCode() GetHashCode() GetHashCode() GetHashCode()

Returns the hash code for this instance.

(Inherited from DtsObject)
LoadFromXML(XmlNode, IDTSEvents) LoadFromXML(XmlNode, IDTSEvents) LoadFromXML(XmlNode, IDTSEvents) LoadFromXML(XmlNode, IDTSEvents)

This method is not callable by your application code. Loads a package containing precedence constraints that are saved as .xml, use the LoadPackage(String, IDTSEvents) method.

SaveToXML(XmlDocument, XmlNode, IDTSEvents) SaveToXML(XmlDocument, XmlNode, IDTSEvents) SaveToXML(XmlDocument, XmlNode, IDTSEvents) SaveToXML(XmlDocument, XmlNode, IDTSEvents)

This method is not callable by your application code. Saves a package as .xml, use the SaveToXml(String, Package, IDTSEvents) method.

Events

Disposed Disposed Disposed Disposed

Adds an event handler to listen to the Disposed event on the precedence constraint.
