Class DeclarationWalker

java.lang.Object

org.mule.runtime.extension.api.introspection.declaration.fluent.util.DeclarationWalker

public abstract class DeclarationWalker
extends Object

Navigates a ExtensionDeclaration 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(WithOperationsDeclaration, OperationDeclaration) 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(ParameterizedInterceptableDeclaration, ParameterDeclaration), etc.
