Inheritance – AEM by Kiran Vedantam
Abstract
There are many ways inheritance is implemented in AEM. For today’s topic, we would be discussing a couple of use-cases on how to access the properties from either ancestral pages or components Use case1: Accessing a page property that is authored on the home page into its child pages using java code. Solution: HierarchyNodeInheritanceValueMap An InheritanceValueMap for a given page resource that will inherit values from ancestral pages. On my /content/allaem/us/en page, I have added a property A new object is created for HierarchyNodeInheritanceValueMap and current page content resource is passed into it as a parameter. Here, the InheritanceValueMap checks for “jcr:description” in /content/allaem/us/en/home/jcr:content /content/allaem/us/en/jcr:content /content/allaem/us/jcr:content /content/allaem/jcr:content If the property is found nowhere, null is returned. This model is now referenced in the text component’s htl in the below way
${text @ context = textModel.isRichText ? 'html' : 'text'}
Inheritance Property is: ${inheritance.description}
