ro.isdc.wro.model.resource.processor.ResourcePreProcessor
Perform actual processing of the resource content from the {@link Reader} and writes the processed content to the{@link Writer}. The processor should focus only on transformation. If a processing fails, it is preferred to propagate the exception, because wro4j can allow custom behavior for this situation. It is possible to treat the exceptions by leaving the processed output unchanged, but in this case you may not benefit of global configuration. @author Alex Objelean @created Created on Nov 19, 2008
