Class ExtensionModelHelper

java.lang.Object

org.mule.runtime.ast.internal.model.ExtensionModelHelper

public class ExtensionModelHelper
extends Object

Helper class to work with a set of ExtensionModels

Contains a cache for searches within the extension models so we avoid processing each extension model twice.

It's recommended that the application only has one instance of this class to avoid processing the extension models several times.
