Interface ResourceTransformer


  • public interface ResourceTransformer
    A transformer is used to read a Resource and pass it through a transformation stage, to get a stream that can be used on the client side. Examples of this are languages that "compile" to JavaScript, or any of a few higher-level versions of CSS that are compiled to standard CSS. ResourceTransformers are contributed to the StreamableResourceSource service.
