public final class MediaTypes extends Object
Media type detection based on a resource.

The media type detection uses the following algorithm:

  • Queries MediaTypeDetector services in priority order
  • Checks all META-INF/media-types.properties files on classpath for a mapping (suffix=media type)
  • Checks built-in mapping provided by Helidon (with the usual the web relevant media types)
