org.mule.runtime.extension.api.IdempotentExtensionWalker

public abstract class IdempotentExtensionWalker
extends ExtensionWalker

A ExtensionWalker which assures that each component is visited only once, making it easy to handle the fact that some components such as OperationModel, SourceModel, ConnectionProviderModel, etc, implement the flyweight pattern, which means that the same instance might be present at different levels.

The use of this walker makes it unnecessary to manually control if a given component has already been seen.
