All Implemented Interfaces:

Callable<IFileProcessorFutureResult>

public class RecursiveParserWrapperFSConsumer
extends AbstractFSConsumer

Basic FileResourceConsumer that reads files from an input directory and writes content to the output directory.

This tries to catch most of the common exceptions, log them and store them in the metadata list output.

Method Detail

processFileResource

public boolean processFileResource(FileResource fileResource)

Description copied from class: FileResourceConsumer

Main piece of code that needs to be implemented. Clients are responsible for closing streams and handling the exceptions that they'd like to handle.

Unchecked throwables can be thrown past this, of course. When an unchecked throwable is thrown, this logs the error, and then rethrows the exception. Clients/subclasses should make sure to catch and handle everything they can.

The design goal is that the whole process should close up and shutdown soon after an unchecked exception or error is thrown.

Make sure to call FileResourceConsumer.incrementHandledExceptions() appropriately in your implementation of this method.

Specified by:

processFileResource in class FileResourceConsumer

Parameters:

fileResource - resource to process

Returns:

whether or not a file was successfully processed

getOutputEncoding

public String getOutputEncoding()

setOutputEncoding

public void setOutputEncoding(String outputEncoding)
