Method Detail

process

public void process(Resource resource,
                    Reader reader,
                    Writer writer)
             throws IOException
Process a content supplied by a reader and perform some sort of processing. It is important to know that you should use reader for processing instead of trying to access the resource original content using Resource, because this way you can ignore the other preProcessors from the chain.
It is not require to explicitly handle exception. When the processing fails, the following can happen:
It is not required to close the reader and writers, because these will be closed for you.

Specified by:
process in interface ResourcePreProcessor
Overrides:
process in class ProcessorDecorator
Parameters:
resource - the original resource as it found in the model.
reader - Reader used to read processed resource content.
writer - Writer where used to write processed results.
Throws:
IOException - when an exception occurs. The future version will change the exception type to Exception, because any exception may occur during processing. The processing failure will be handled based on value of WroConfiguration.isIgnoreFailingProcessor() configuration flag.
