public ref class Constraint abstract : NativeActivity

NameDescription
System_CAPS_protpropertyCacheId

Gets the identifier of the cache that is unique within the scope of the workflow definition.(Inherited from Activity.)

System_CAPS_protpropertyCanInduceIdle

Gets or sets a value that indicates whether the activity can cause the workflow to become idle.(Inherited from NativeActivity.)

System_CAPS_protpropertyConstraints

Gets a collection of Constraint activities that can be configured to provide validation for the Activity.(Inherited from Activity.)

System_CAPS_pubpropertyDisplayName

Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking.(Inherited from Activity.)

System_CAPS_pubpropertyId

Gets an identifier that is unique in the scope of the workflow definition.(Inherited from Activity.)

System_CAPS_protpropertyImplementation

The execution logic of the activity.(Inherited from NativeActivity.)

System_CAPS_protpropertyImplementationVersion

Gets or sets the implementation version of the activity.(Inherited from NativeActivity.)

NameDescription
System_CAPS_protmethodAbort(NativeActivityAbortContext^)

When implemented in a derived class, takes actions in response to the activity being aborted.(Inherited from NativeActivity.)

System_CAPS_pubmethodSystem_CAPS_staticAddValidationError(NativeActivityContext^, ValidationError^)

Adds a validation error to a list of run-time validation errors that are attached to the execution context.

System_CAPS_protmethodCacheMetadata(ActivityMetadata)

Not implemented. Use the CacheMetadata method instead.(Inherited from NativeActivity.)

System_CAPS_protmethodCacheMetadata(NativeActivityMetadata)

Creates a NativeActivityMetadata object that contains runtime arguments for the workflow validation process.(Overrides NativeActivity::CacheMetadata(NativeActivityMetadata).)

System_CAPS_protmethodCancel(NativeActivityContext^)

When implemented in a derived class, runs logic to cause graceful early completion of the activity.(Inherited from NativeActivity.)

System_CAPS_pubmethodEquals(Object^)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodExecute(NativeActivityContext^)

Invokes the process that validates an activity.(Overrides NativeActivity::Execute(NativeActivityContext^).)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_protmethodOnCreateDynamicUpdateMap(NativeActivityUpdateMapMetadata^, Activity^)

Raises an event when creating a map for the dynamic update.(Inherited from NativeActivity.)

System_CAPS_protmethodOnCreateDynamicUpdateMap(UpdateMapMetadata^, Activity^)

Raises an event when creating a map for the dynamic update.(Inherited from NativeActivity.)

System_CAPS_protmethodOnExecute(NativeActivityContext^, Object^, ValidationContext^)

When implemented by a derived class, validates the specified object using the specified native activity and validation contexts.

System_CAPS_pubmethodShouldSerializeDisplayName()

Indicates whether the DisplayName property should be serialized.(Inherited from Activity.)

System_CAPS_pubmethodToString()

Returns a String that contains the Id and DisplayName of the Activity.(Inherited from Activity.)

System_CAPS_protmethodUpdateInstance(NativeActivityUpdateContext^)

Updates the instance of NativeActivity.(Inherited from NativeActivity.)

NameDescription
System_CAPS_pubfieldSystem_CAPS_staticValidationErrorListPropertyName

The name for an activity constraint property that is a list of workflow run-time validation errors.
