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
- 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.
onException
protected void onException(WroRuntimeException e)
- Invoked when a processing exception occurs.
newEngine
protected JsonHPack newEngine()
- Returns:
- the
JsonHPack
engine implementation. Override it to provide a different version of the
json.hpack.js library. Useful for upgrading the processor outside the wro4j release.
process
public void process(Reader reader,
Writer writer)
throws IOException
- Perform actual resource processing. The content to be processed is read
from source Reader and is written to destination Writer. It is the client
responsibility to close both: Reader and writer.
- Specified by:
process
in interface ResourcePostProcessor
- Parameters:
reader
- source stream.writer
- destination stream.
- Throws:
IOException
