Class ExtensionWalker

java.lang.Object

org.mule.runtime.extension.api.ExtensionWalker

Direct Known Subclasses:

IdempotentExtensionWalker

public abstract class ExtensionWalker
extends Object

Navigates a ExtensionModel and invokes methods when important model components are found.

This is useful to centralize the logic of how to iterate through a model's structure without coupling to it. For example, the onOperation(HasOperationModels, OperationModel) method allows handling operations without requiring to know that they can exist at global or configuration level. Something similar can be said about the onParameter(ParameterizedModel, ParameterModel), etc.
