public sealed class AggregatableAttribute : InstanceLevelAspect, ITypeLevelAspect, ITypeLevelAspectBuildSemantics, IAspectBuildSemantics, IValidableAnnotation, ICloneAwareAspect, IInstanceScopedAspect, IAttachable, IAggregatable, IAdviceProvider, IAspectProvider, IAspect, IService
Remarks

This aspect implements the IAggregatable interface, which exposes members such as VisitChildren(ChildVisitor, ChildVisitorOptions, Object) and Parent.

The AggregatableAttribute aspect is implicitly used by several other aspects, including all threading models.

When a class has the AggregatableAttribute aspect, its reference-type fields and automatic properties must be annotated with one of the following attributes: ChildAttribute, ReferenceAttribute or ParentAttribute.

Target classes can customize the AggregatableAttribute aspect by implementing one or many of the members documented in the AggregatableAttributeTargetClass class.
