public sealed class PrecedenceConstraint : DtsObject, IDTSName, 
	IDTSPersist, IComponent, IDisposable

NameDescription
System_CAPS_pubpropertyConstrainedExecutable

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

System_CAPS_pubpropertyCreationName

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.

System_CAPS_pubpropertyDescription

Gets or sets a description for the constraint.

System_CAPS_pubpropertyEvalOp

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

System_CAPS_pubpropertyEvaluatesTrue

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

System_CAPS_pubpropertyExpression

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

System_CAPS_pubpropertyID

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

System_CAPS_pubpropertyLogicalAnd

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

System_CAPS_pubpropertyName

Gets or sets the unique name of the precedence constraint.

System_CAPS_pubpropertyParent

Gets the parent container of the PrecedenceConstraint.

System_CAPS_pubpropertyPrecedenceExecutable

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

System_CAPS_pubpropertySite

This API supports the product infrastructure and is not intended to be used directly from your code. Gets or sets the site of the precedence constraint.

System_CAPS_pubpropertyValue

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

NameDescription
System_CAPS_pubmethodDispose()

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

System_CAPS_pubmethodEquals(Object)

Determines whether two object instances are equal.(Inherited from DtsObject.)

System_CAPS_pubmethodGetHashCode()

Returns the hash code for this instance.(Inherited from DtsObject.)

System_CAPS_pubmethodGetType()

(Inherited from Object.)

System_CAPS_pubmethodLoadFromXML(XmlNode, IDTSEvents)

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

System_CAPS_pubmethodSaveToXML(XmlDocument, XmlNode, IDTSEvents)

This method is not callable by your application code. Saves a package as .xml, use the Application.SaveToXml method.

System_CAPS_pubmethodToString()

(Inherited from Object.)

NameDescription
System_CAPS_pubeventDisposed

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.
