ResourceTransformer (Tapestry API - 5.7.0)

```
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.
