Need clarification on topic https://sling.apache.org/documentation/tutorials-how-tos/getting-resources-and-properties-in-sling.html

Question

Hi All,It is mentioned here that Note: resource.adaptTo(Node.class) may return null if the resource is not backed by a JCR node. This is particularly the case for NonExistingResource resources or resource provided by a non-JCR resource provider.1] But isn't it something like every resource[probably a node] always has a jcr:content associated with it.Can you please let me know on this.

Not in all cases, you can create a so called SyntheticResource

https://docs.adobe.com/docs/en/cq/5-6-1/javadoc/org/apache/sling/api/resource/SyntheticResource.html

I would always go for resource.getValueMap(), this is much easier way to access properties.

Hi Feike,Thank you for your reply.I was not aware that something like this exists. But what exactly would be the purpose of SyntheticResource. If you can provide any example, it would be helpful.
