Description copied from interface: ContentResolverService

This method will accept a URL and then return a handle to stream the resource from the StorageProvider.

If the content is requested with certain effects applied, the method will search for a cached copy of the content with those effects applied. If no cached copy is found, then the base content is retrieved, the effects are applied to it, the modified version is cached in the storage provider, and then returned. Of course, if the base content is not found, this method will simply return an Optional.empty().

Specified by:

readResourceWithMetadata in interface ContentResolverService

Parameters:

url - the URL of the digital content to fetch

imageEffectsTags - the image effects tags to apply to the content; a map of effects to their values.

contextInfo - context information surrounding sandboxing and multitenant state

Returns:

an Optional containing the ResourceWithMetadata, or Optional.empty() if not found
